The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Dichloro(1,5-cyclooctadiene)platinum(II)(SMILESS: C1=CCC/C=CCC/1.[Pt+2].[Cl-].[Cl-],cas:12080-32-9) is researched.SDS of cas: 1798-99-8. The article 《Understanding Doping Effects on Electronic Structures of Gold Superatoms: A Case Study of Diphosphine-Protected M@Au12 (M = Au, Pt, Ir)》 in relation to this compound, is published in Inorganic Chemistry. Let’s take a look at the latest research on this compound (cas:12080-32-9).

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.

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 Dynamics of the efficient cyclometalation of the undercoordinated organoplatinum complex [Pt(COD)(neoPh)]+ (neoPh = 2-methyl-2-phenylpropyl), the main research direction is platinum metallacycle cyclooctadiene complex preparation CH activation neophyl ligand; crystal structure platinum metallacycle cyclooctadiene complex; mol structure platinum metallacycle cyclooctadiene complex; cyclometalation mechanism platinum neophyl cyclooctadiene complex potential energy surface.Product Details of 12080-32-9.

Reaction of the organoplatinum complex [Pt(COD)(neoPh)Cl] (neoPh = (2-methyl-2-phenylpropyl)) with Ag(PF6) leads to the undercoordinated cationic complex [Pt(COD)(neoPh)]+ which rapidly and quant. rearranges to the complex [Pt(COD)(κ2-neoPh)] through intramol. cyclometalation. Detailed NMR spectroscopy and single crystal XRD reveal a doubly metalated neoPh ligand. In line with exptl. observations, ab initio mol. dynamics simulations confirm that the cyclometalation reaction is exothermic and has a relatively low free energy barrier. In addition, the simulations provide detailed insight into the reaction mechanism, showing that an intermediate species exists in which the newly formed Pt-C bond coexists with a covalent Pt-H bond involving the leaving proton. The latter is found to eventually transfer onto an acetone solvent mol.

Recommanded Product: 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 Encapsulation of FePt and FePt3 alloys inside carbon-foam materials. Author is Boi, Filippo S.; Wang, Jiayu; He, Yi; Wen, Jiqiu; Wang, Shanling; Zhang, Xi; Yu, Tian; Shi, Lin; Ma, Qiuyan; Lan, Mu; Lei, Li; Xiang, Gang.

We demonstrate an advanced chem. vapor deposition (CVD) approach in which the addition of Pt-containing hydrocarbons to ferrocene allows the nucleation of a novel carbon-foam material completely filled with elemental Fe and Pt crystal-phases. These phases are then found to alloy into tetragonal FePt and cubic FePt3 in specific annealing conditions. A dependence of the FePt nucleation on the Ar/H2 flow rate is reported. In addition, high pressure (5 GPa) experiments are found to favor the formation of a single FePt3 encapsulated phase together with the nucleation of C-O rich carbon layers in the foam surface.

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 Synthesis and structure of thienyl Fischer carbene complexes of PtII for application in alkyne hydrosilylation, published in 2021, which mentions a compound: 12080-32-9, Name is Dichloro(1,5-cyclooctadiene)platinum(II), Molecular C8H12Cl2Pt, Application of 12080-32-9.

Transmetalation of Group 6 thienylene Fischer carbene complexes to Pt(II) precursors yielded new examples of neutral Pt(II) bisethoxycarbene complexes with either 2-thienyl (T) or 5-thieno[2,3-b]thienylene (TT) carbene substituents. The use of analogous aminocarbene group 6 precursors proceeded to give isomeric Pt(II) product mixtures where the resultant bisaminocarbene ligands displayed different orientations due to restricted rotation around the Pt-aminocarbene bond caused by the sterically demanding TT substituents. The well-defined Pt(II) ethoxycarbene complexes were screened as catalyst precursors in the benchmark hydrosilylation reaction employing phenylacetylene and triethylsilane substrates. Marked selectivity for the β-E isomer (E)-triethyl(styryl)silane was observed, and the (pre)catalysts proved recyclable, active in solvent-free reactions, and displaying a high alkyne functional group tolerance.

Through the article, more information about this compound (cas:12080-32-9) is conveyed.

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.

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.Application In Synthesis of Dichloro(1,5-cyclooctadiene)platinum(II).Moon, Sangjoon; Horiuchi, Shinnosuke; Sakuda, Eri; Ito, Akitaka; Arikawa, Yasuhiro; Umakoshi, Keisuke published the article 《Synthesis and photophysical properties of butterfly-shaped dinuclear Pt(II) complex having NHC-based chelate ligands》 about this compound( cas:12080-32-9 ) in Inorganica Chimica Acta. Keywords: dinuclear platinum pyridylimidazole pyrazole complex preparation crystal structure luminescence; DFT calculation dinuclear platinum pyridylimidazole pyrazole complex. Let’s learn more about this compound (cas:12080-32-9).

A butterfly-shaped dinuclear Pt(II) complex having pyridyl-NHC chelate ligands and bridging Me2pz ligands was synthesized. The crystal structure of the Pt2 complex showed short intramol. Pt···Pt distance (3.129 Å) and unique packing structure containing 1-dimensional infinite pore that was filled with solvent mols. The absorbance was proportional to the concentration of Pt2 complex and no significant bands appeared even in high concentration (up to 100 μM). The Pt2 complex showed bluish-green emission (λmax = 459 nm) in the solid state at 298 K (λex = 330 nm). TD-DFT calculation revealed that the lowest-energy absorption bands are mainly assigned to the combination of metal-to-ligand charge transfer (MLCT) and ligand-to-ligand charge transfer (LLCT) transitions.

Author is Mastrocinque, Francesco; Anderson, Craig M.; Elkafas, Adel M.; Ballard, Isabel V.; Tanski, Joseph M..

Cyclometalated platinum complexes I (R = Me, 3-thienylmethyl; X1, X2 = H, benzo) were prepared by a two-step, one-pot procedure and characterized; the complexes showed photoluminescence at 450-550 nm. Thiophene and benzothiophene ligands containing N-heterocyclic carbene (NHC) moieties were used to synthesize five and six-membered Pt(II) metallacycles. Ligand scaffolding was synthesized using two methods. The ligands were synthesized using a coupling reaction, utilizing Cu2O as the catalyst or were synthesized using a nucleophilic substitution reaction. The ligands were then metalated by chelate-assisted C-H activation. The synthesis, characterization, reactivity, and photophys. properties of these NHC-functionalized, cyclometalated products are reported.
