Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Inorganic Chemistry called Luminescent Platinum(II) Complexes of N^N-^N Amido Ligands with Benzannulated N-Heterocyclic Donor Arms: Quinolines Offer Unexpectedly Deeper Red Phosphorescence than Phenanthridines, Author is Mandapati, Pavan; Braun, Jason D.; Killeen, Charles; Davis, Rebecca L.; Williams, J.

A platform for investigating the impact of π-extension in benzannulated, anionic pincer-type N^N-^N-coordinating amido ligands and their Pt(II) complexes is presented. Based on bis(8-quinolinyl)amine, sym. and asym. proligands bearing quinoline or π-extended phenanthridine (3,4-benzoquinoline) units are reported, along with their red-emitting, phosphorescent Pt(II) complexes of the form (N^N-^N)PtCl. Comparing the photophys. properties of complexes of (quinolinyl)amido ligands with those of π-extended (phenanthridinyl)amido analogs revealed a counterintuitive impact of site-selective benzannulation. Contrary to conventional assumptions regarding π-extension, and in contrast to isoenergetic lowest energy absorption bands and a red shift in fluorescence from the organic proligands, a blue shift of nearly 40 nm in the emission wavelength is observed for Pt(II) complexes with more extended bis(phenanthridinyl) ligand π-systems. Comparing the ground state and triplet excited state structures optimized from d. functional theory (DFT) and time-dependent-DFT calculations, we trace this effect to a greater rigidity of the benzannulated complexes, resulting in a higher energy emissive triplet state, rather than to a significant perturbation of orbital energies caused by π-extension. A counterintuitive impact of π-extension on luminescence from deep red emitting Pt(II) complexes of benzannulated, anionic pincer-type N^N-^N-coordinating amido ligands is reported. Contrary to conventional assumptions, isoenergetic lowest energy absorption bands and a red shift in fluorescence from the organic proligands, a blue shift in the emission wavelength is observed for Pt(II) complexes with more extended bis(phenanthridinyl) π-systems, traced to a greater rigidity of the benzannulated complexes and a higher energy triplet state.

Synthetic Route of C8H12Cl2Pt. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Platinum ω-Alkenyl Compounds as Chemical Vapor Deposition Precursors. Mechanistic Studies of the Thermolysis of Pt[CH2CMe2CH2CH=CH2]2 in Solution and the Origin of Rapid Nucleation. Author is Liu, Sumeng; Zhang, Zhejun; Abelson, John R.; Girolami, Gregory S..

Cis-bis(η1,η2-2,2-dimethylpent-4-en-1-yl)platinum, Pt[CH2CMe2CH2CH=CH2]2 (3), is a recently discovered CVD precursor for the deposition of highly smooth Pt thin films without nucleation delays on a variety of substrates. This paper describes detailed mechanistic studies of the pathway by which 3 reacts upon being heated in solution In various solvents between 90 and 130°, 3 decomposes to generate ~1 equiv of 4,4-dimethylpentenes by addition of a H atom to the pentenyl ligands in 3. The extra H atoms arise by dehydrogenation of other pentenyl ligands; some of these dehydrogenated ligands are released as Me-substituted methylenecyclobutanes and cyclobutenes. A combination of isotope labeling and kinetic studies suggests that 3 decomposes by C-H activation of both allylic and olefinic C-H bonds to give transient Pt hydride intermediates, followed by reductive elimination steps to form the pentene products, but that the exact mechanism is solvent-dependent. In C6F6, solvent association occurs before C-H bond activation, and the rate-determining step for thermolysis is most likely the formation of a Pt σ complex. In hydrocarbon solvents, the solvent is little involved before C-H bond activation, and the rate-determining step is most likely the formation of a Pt σ complex only for γ-C-H and ε-C-H bond activation, but cleavage or formation of a C-H bond for δ-C-H bond activation. A comparison of the thermolysis reactions under CVD conditions and in solution suggests that the high smoothness of the CVD-grown films is due in part to rapid nucleation (which is a consequence of the availability of low-barrier C=C bond dissociation pathways) and in part to the formation of C-containing species that passivate the Pt surface.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Roles played by carbene substituents during ligand transfer reactions between tungsten fischer carbene complexes and [Pt(COD)Cl2], published in 2021-12-01, which mentions a compound: 12080-32-9, mainly applied to tungsten Fischer carbene ligand transfer reaction platinum chloride; platinum biscarbene triscarbene carbene complex preparation crystal structure; mol structure platinum biscarbene triscarbene carbene complex, Formula: C8H12Cl2Pt.

Fischer carbene ligand transfer reactions from [W{C(X)(C6H4-4-R)}(CO)5] (X = OEt: a series; X = NMe2: b series), containing remote tertiary amino substituents R = R’2N at the Ph ring, to Pt(II) of [Pt(COD)Cl2] precursors, were studied. The number of carbene ligands transferred per Pt ion in these cases are determined by the electronic and steric properties of the heteroatoms of the carbene ligand. Thus, neutral bis(carbene) complexes, [Pt{C(X)(C6H4-4-R)}2Cl2], (R = H (1a); R = NR’2 and R’ = Me (2a), Ph (3a), or 4-BrC6H4 (4a)), are formed from the ethoxycarbene precursors (X = OEt), while cationic tris(carbene) complexes [Pt{C(X)(C6H4-4-R)}3Cl]+ Z-, (R = H (1b) and R = NR’2 and R’ = Me (2b), Ph (3b), or 4-BrC6H4 (4b)) were obtained from the aminocarbene precursors (X = NMe2), the latter with different counterions Z- = Cl-, [W(CO)5Cl]- or PF-6. Electro- and spectroelectrochem. studies indicate consecutive oxidations of the individual carbene ligands, but also a lack of electronic interactions across the (X)C:Pt:C(X) linkages.

Application of 12080-32-9. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Understanding Doping Effects on Electronic Structures of Gold Superatoms: A Case Study of Diphosphine-Protected M@Au12 (M = Au, Pt, Ir). Author is Hirai, Haru; Takano, Shinjiro; Nakamura, Toshikazu; Tsukuda, Tatsuya.

Dopants into ligand-protected Au superatoms have been hitherto limited to group X-XII elements (Pt, Pd, Ag, Cu, Hg, and Cd). To expand the scope of the dopants to the group IX elements, the authors synthesized unprecedented [IrAu12(dppe)5Cl2]+ [IrAu12; dppe = 1,2-bis(diphenylphosphino)ethane] and [PtAu12(dppe)5Cl2]2+ (PtAu12) and compared their electronic structures with that of [Au13(dppe)5Cl2]3+ (Au13). Single-crystal x-ray diffractometry, 31P{1H} NMR, and Ir L3-edge extended X-ray absorption fine structure anal. of IrAu12 revealed that the single Ir atom is located at the center of the icosahedral IrAu12 core. Electrochem. anal. demonstrated that the energy levels of the highest occupied MOs are upshifted in the order of Au13 < PtAu12 < IrAu12. This trend was qual. explained in such a manner that the jellium core potential at the central position becomes shallower by replacing Au+ with Pt0 and further with Ir-. IrAu12 underwent reversible redox reactions between the charge states of 1+ and 2+. The gradual increase of the energy gap between the HOMO and LUMO in the order of Au13 < PtAu12 < IrAu12 was observed by electrochem. measurement and optical spectroscopy. This study provides a simple guiding principle to tune the electronic structures of heterometal-doped superatoms. The orbital energies of [IrAu12(dppe)5Cl2]+ (IrAu12) and [PtAu12(dppe)5Cl2]2+ (PtAu12) were compared with those of [Au13(dppe)5Cl2]3+ (Au13) by electrochem. anal. The superat. orbitals were shifted up in the order of IrAu12 > PtAu12 > Au13. The result was explained by the upshift of the bottom of the effective potential due to different formal charge states of the dopants. Whereas Au was incorporated as Au+, Ir and Pt were incorporated as Ir- and Pt0, resp.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Dichloro(1,5-cyclooctadiene)platinum(II)( cas:12080-32-9 ) is researched.Category: alcohols-buliding-blocks.Gholivand, Khodayar; Maghsoud, Yazdan; Kahnouji, Mohammad; Hosseini, Mahdieh; Satari, Mohammad; Abdolmaleki, Parviz; Roe, Stephen Mark published the article 《Platinum(II) complexes containing hydrazide-based aminophosphine ligands: Synthesis, molecular structures, computational investigation and evaluation as antitumour agents》 about this compound( cas:12080-32-9 ) in Applied Organometallic Chemistry. Keywords: DFT FMO platinum chloride diphenylphosphinoamino complex; antitumor activity platinum chloride diphenylphosphinoamino complex; crystal structure platinum chloride diphenylphosphinoamino complex preparation. Let’s learn more about this compound (cas:12080-32-9).

Four new N,N-bis(diphenylphosphino)amine ligands (amine = 1-amino-4-methylpiperazine (L1), N-aminophthalimide (L2), 4-aminomorpholine (L3) and hydrazine dihydrochloride (L4)) and their Pt(II) complexes C1, C2, C3 and C4 were synthesized and characterized using IR and NMR spectroscopies. The crystal structures of C1, C2 and C3 were determined using single-crystal x-ray diffraction techniques. The antitumor activities of the synthesized complexes determined using MTT assay on MDA-MB-231 cell line revealed that the studied complexes, especially C2, significantly suppressed the proliferation of these cancer cells in a dose- and time-dependent manner (e.g. at a complex concentration of 100 μg ml-1, in 24 h, the reduction of the cell viability was 88.00, 38.89, 83.35 and 64.28% for C1-C4, resp.). Theor. approaches were also used to investigate the energy and the nature of metal-ligand and metal-chlorine interactions in the complexes, which could explain their biol. activities. The interaction between ligand and Pt is stronger in C2, while the Pt-Cl interaction is weaker in this complex in comparison with the other complexes.

As far as I know, this compound(12080-32-9)Category: alcohols-buliding-blocks can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.

A Journal, Article, Chemistry – A European Journal called Bright Luminescent Platinum(II)-Biaryl Emitters Synthesized Without Air-Sensitive Reagents, Author is Wakasugi, Chuei; Yoshida, Masaki; Sameera, W. M. C.; Shigeta, Yasuhiro; Kobayashi, Atsushi; Kato, Masako, which mentions a compound: 12080-32-9, SMILESS is C1=CCC/C=CCC/1.[Pt+2].[Cl-].[Cl-], Molecular C8H12Cl2Pt, HPLC of Formula: 12080-32-9.

Transition-metal complexes bearing biaryl-2,2′-diyl ligands tend to show intense luminescence. However, difficulties in synthesis have prevented their further functionalization and practical applications. Herein, a series of platinum(II) complexes bearing biaryl-2,2′-diyl ligands, which have never been prepared in air, were synthesized through transmetalation and successive cyclometalation of biarylboronic acids. This approach does not require any air- or moisture-sensitive reagents and features a simple synthesis even in air. The resulting (Et4N)2[Pt(m,n-F2bph)(CN)2] (m,n-F2bph=m,n-difluorobiphenyl-2,2′-diyl) complexes exhibit intense green emissions with high quantum efficiencies of up to 0.80 at 298 K. The emission spectral fitting and variable-temperature emission lifetime measurements indicate that the high quantum efficiency was achieved because of the tight packing structure and strong σ-donating ability of bph.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Ditopic dithiocarbamate ligands for the production of trinuclear species, published in 2020-01-31, which mentions a compound: 12080-32-9, Name is Dichloro(1,5-cyclooctadiene)platinum(II), Molecular C8H12Cl2Pt, Related Products of 12080-32-9.

Reactions of group 10 transition metals with the ditopic ligand dipicolyldithiocarbamate (DPDTC) were performed. Thus, 1:2 reactions of [Ni(CH3COO)2], [Pd(COD)Cl2] or [Pt(COD)Cl2] with DPDTC produced monomeric complexes of the type [M(κ2-SCS-DPDTC)2, M = Ni (1), Pd (2) or Pt (3)] with the dithiocarbamate ligand (DTC) coordinated in a typical chelate κ2-SCS fashion. Interestingly, the reaction of [NiCl2] with DPDTC, under similar conditions, afforded the organic compound 2-(pyridin-2-ylmethyl)imidazo[1,5-a]pyri-dine-3(2 H)-thione (4) as unique product. In order to prove the ditopic nature of the ligand DPDTC, complex [Pd(κ2-SCS-DPDTC)2] (2) was further reacted with [ZnCl2] in a 1:2 M ratio to yield the trinuclear complex [Cl2Zn(κ2-NN-DPDTC-SCS-κ2)Pd(κ2-SCS-DPDTC-NN-κ2)ZnCl2] (5). The mol. structures of all compounds were determinate by typical anal. techniques including the unequivocal determination of all structures by single crystal x-ray diffraction anal. As expected, complexes 1-3 are isostructural, and the metal centers exhibiting slightly distorted square-planar geometries. While in 5, the trinuclear nature of the complex in confirmed exhibiting a nice combination of tetrahedral-square planar-tetrahedral geometries for the Zn-Pd-Zn centers resp.

Keywords: platinum heterocyclic carbene synthesis anticancer asparagine synthetase proteome; N-heterocyclic carbenes; antitumor agents; asparagine synthetase; platinum complexes; thermal proteome profiling.They researched the compound: Dichloro(1,5-cyclooctadiene)platinum(II)( cas:12080-32-9 ).Name: Dichloro(1,5-cyclooctadiene)platinum(II). Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:12080-32-9) here.

New anticancer platinum(II) compounds with distinctive modes of action are appealing alternatives to combat the drug resistance and improve the efficacy of clin. used platinum chemotherapy. Herein, we describe a rare example of an antitumor PtII complex targeting a tumor-associated protein, rather than DNA, under cellular conditions. Complex [(bis-NHC)Pt(bt)]PF6 (1a; Hbt=1-(3-hydroxybenzo[b]thiophen-2-yl)ethanone) overcomes cisplatin resistance in cancer cells and displays significant tumor growth inhibition in mice with higher tolerable doses compared to cisplatin. The cellular Pt species shows little association with DNA, and localizes in the cytoplasm as revealed by nanoscale secondary ion mass spectrometry. An unbiased thermal proteome profiling experiment identified asparagine synthetase (ASNS) as a mol. target of 1a. Accordingly, 1a treatment reduced the cellular asparagine levels and inhibited cancer cell proliferation, which could be reversed by asparagine supplementation. A bis-NHC-ligated Pt species generated from the hydrolysis of 1 a forms adducts with thiols and appears to target an active-site cysteine of ASNS.

Application In Synthesis of Dichloro(1,5-cyclooctadiene)platinum(II). The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Room-Temperature Phosphorescent Platinum(II) Alkynyls with Microsecond Lifetimes Bearing a Strong-Field Pincer Ligand. Author is Liska, Tadeas; Swetz, Anna; Lai, Po-Ni; Zeller, Matthias; Teets, Thomas S.; Gray, Thomas G..

The use of organometallic triplet emitters in organic light emitting diodes (OLEDs) is motivated by the premise of efficient intersystem crossing leading to unit internal quantum efficiencies. However, since most devices are based on solid-state components, an inherent limitation to square-planar Pt(II) phosphors is their tendency toward aggregation-based quenching. Here, a new class of emissive, four-coordinate Pt(II) species based on the bisimidazolyl carbazolide (BIMCA) ligand is introduced, which displays highly efficient, long-lived solid-state phosphorescence at room temperature A set of four BIMCAPt Ph acetylides were synthesized that emit in the green (λmax=507-540 nm) with >60% quantum yield and millisecond lifetimes. The structures of the resulting species reveal a nonplanar structure imposed by steric clashes between BIMCA and the iodo or alkynyl co-ligand. Ground-state and photophys. characterization are presented. D. functional theory calculations indicate that the BIMCA ligand dominates the frontier orbitals along with the 1st Franck-Condon singlet and triplet excited states.
