Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 12080-32-9, is researched, SMILESS is C1=CCC/C=CCC/1.[Pt+2].[Cl-].[Cl-], Molecular C8H12Cl2PtJournal, Synlett called Confining the Inner Space of Strained Carbon Nanorings, Author is Grabicki, Niklas; Dumele, Oliver, the main research direction is cyclopyrenylene macrocycle confining inner space strained carbon nanoring preparation; crystal mol structure cyclopyrenylene macrocycle carbon nanoring.Synthetic Route of C8H12Cl2Pt.

Strained aromatic macrocycles based on cycloparaphenylenes (CPPs) are the shortest repeating units of armchair single-walled carbon nanotubes. Since the development of several new synthetic methodologies for accessing these structures, their properties have been extensively studied. Besides the fundamental interest in these novel mol. scaffolds, their application in the field of materials science is an ongoing topic of research. Most of the reported CPP-type macrocycles display strong binding toward fullerenes, due to the perfect match between the convex and concave π-surfaces of fullerenes and CPPs, resp. Highly functionalized CPP derivatives capable of supramol. binding with other mols. are rarely reported. The synthesis of highly functionalized [ n]cyclo-2,7-pyrenylenes leads to CPP-type macrocycles with a defined cavity capable of binding non-fullerene guests with high association constants

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 12080-32-9, is researched, Molecular C8H12Cl2Pt, about Ditopic dithiocarbamate ligands for the production of trinuclear species, the main research direction is ditopicdipicolyl dithiocarbamate nickel palladium platinum zinc preparation crystal structure; crystal mol structure dipicolyldithiocarbamate nickel palladium platinum zinc complex.Recommanded Product: Dichloro(1,5-cyclooctadiene)platinum(II).

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.

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 Mustards-Derived Terpyridine-Platinum Complexes as Anticancer Agents: DNA Alkylation vs. Coordination, published in 2021-02-15, which mentions a compound: 12080-32-9, Name is Dichloro(1,5-cyclooctadiene)platinum(II), Molecular C8H12Cl2Pt, Name: Dichloro(1,5-cyclooctadiene)platinum(II).

The development of bifunctional platinum complexes with the ability to interact with DNA via different binding modes is of interest in anticancer metallodrug research. Therefore, we report platinum(II) terpyridine complexes to target DNA by coordination and/or through a tethered alkylating moiety. The platinum complexes were evaluated for their in vitro antiproliferative properties against the human cancer cell lines HCT116 (colorectal), SW480 (colon), NCI-H460 (non-small cell lung), and SiHa (cervix) and generally exhibited potent antiproliferative activity although lower than their resp. terpyridine ligands. 1H NMR spectroscopy and/or ESI-MS studies on the aqueous stability and reactivity with various small biomols., acting as protein and DNA model compounds, were used to establish potential modes of action for these complexes. These investigations indicated rapid binding of complex PtL3 to the biomols. through coordination to the Pt center, while PtL4 in addition alkylated 9-ethylguanine. PtL3 was investigated for its reactivity to the model protein hen egg white lysozyme (HEWL) by protein crystallog. which allowed identification of the Nδ1 atom of His15 as the binding site.

Name: Dichloro(1,5-cyclooctadiene)platinum(II). The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. 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.

The new ferrocene based bisphosphine [Fe{C5H4P(CCPh)2}2] (1) was synthesized in 82% yield by the treatment of bis(dichlorophosphino)ferrocene [Fe(C5H4PCl2)2] with four equivalent of lithium phenylacetylide. The reactions of 1 with aqueous H2O2, elemental sulfur or selenium afforded bis(chalcogenide) derivatives, [Fe{C5H4P(E)(CCPh)2}2] (2 E = O, 3 E = S, 4 E = Se). The reaction of 1 with [M(NC5H11)2(CO)4] (M = Mo, W), [RuCp(PPh3)2Cl] and [M(COD)Cl2] (M = Pd, Pt) resulted in the formation of the resp. chelate complexes, [Fe{C5H4P(CCPh)2}2{M(CO)4}] (5 M = Mo, 6 M = W), [Fe{C5H4P(CCPh)2}2{RuCp(Cl)}] (8) and [Fe{C5H4P(CCPh)2}2{MCl2}] (9 M = Pd, 10 M = Pt), whereas the reaction of 1 with [Ru(η6-p-cymene)Cl2]2 and [AuCl(SMe2)] yielded the corresponding bimetallic complexes [Fe{C5H4P(CCPh)2}2{RuCl2(η6-p-cymene)}2] (7) and [Fe{C5H4P(CCPh)2}2{AuCl}2] (15). The reactions between 1 and CuX in equimolar ratios also yielded binuclear complexes, [Fe{C5H4P(CCPh)2}2{CuX}2] (11 X = Cl, 12 X = Br, 13 X = I), whereas [Cu(CH3CN)4]BF4 yielded the cationic complex [(Fe{C5H4P(CCPh)2}2)2Cu]BF4 (14). All the compounds were characterized by spectroscopic methods and the structures of complexes 1, 5, 6, 8, 10, 13 and 14 were confirmed by single crystal x-ray diffraction studies.

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 Flexible Platinum(0) Coordination to a Ditungsten Ethanediylidyne, published in 2019, which mentions a compound: 12080-32-9, mainly applied to crystal structure platinum coordinate ditungsten ethanediylidyne complex; mol structure platinum coordinate ditungsten ethanediylidyne complex; platinum NMR coordinate ditungsten ethanediylidyne complex; bis(carbyne)s; carbido ligands; carbynes; dicarbido ligands; polymetallic compounds, Category: alcohols-buliding-blocks.

The lithiocarbyne [W(CLi)(CO)2(Tp*)] (Tp*=hydrotris(3,5-dimethylpyrazol-1-yl)borate) reacts with [PtCl2(L2)] (L2 = 1,5-cyclo-octadiene, norbornadiene) to furnish ditungsten ethanediylidyne complexes, [W2{μ-C2Pt(L2)}(CO)4(Tp*)2], wherein a trigonal platinum(0) center unsym. ligates one W C bond in the solid state but rapidly shimmies between the two W C bonds in solution The η4-dienes are displaced by monodentate CO or isocyanide ligands to provide derivatives where both W C bonds coordinate to a single Pt0 center, attended by significant distortion of the WCCW spine.

Safety of Dichloro(1,5-cyclooctadiene)platinum(II). Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Roles played by carbene substituents during ligand transfer reactions between tungsten fischer carbene complexes and [Pt(COD)Cl2]. Author is Weststrate, Nora-ann; Hassenruck, Christopher; Liles, David C.; Lotz, Simon; Gorls, Helmar; Winter, Rainer F..

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.

Related Products of 12080-32-9. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Bidentate Disilicate Framework for Bis-Grafted Surface Species.

Recent advances in surface organometallic chem. have enabled the detailed characterization of the surface species in single-site heterogeneous catalysts. However, the selective formation of bis-grafted surface species remains challenging because of the heterogeneity of the supporting surface. Herein, the authors introduce a metal complex bearing bidentate disilicate ligands, -OSi(OtBu)2OSi(OtBu)2O-, as a mol. precursor, which has a silicate framework adjacent to the metal (Pt) center. The grafting of the precursors on SiO2 supports (MCM-41 and CARiACT Q10) proceeded through a substitution reaction on the Si atoms of the disilicate ligand, which was verified by the detection of isobutene and tBuOH as the elimination products, to selectively yield bis-grafted surface species. The chem. structure of the surface species was characterized by solid-state NMR, and the chem. shift values of the ancillary ligands and 195Pt nuclei suggested that the bidentate coordination sphere was maintained following grafting.
