Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about Microcalorimetric studies of the thermal decomposition of ammonia-halide and amine-halide complexes of platinum(II), [Pt(NH2R)2X2]. Author is Al Takhin, Ghassan; Skinner, Henry A.; Zaki, Ahmed A..

The standard heats of formation of the crystalline compounds [PtL2X2] [L = NH2R (R = H, Me, CHMe2, Bu, Et, Pr, CH2CHMe2), en, pyridine; X = Cl, Br, I] were derived from the enthalpies of thermal decomposition of their cis isomers at elevated temperatures The enthalpy of sublimation (ΔHsub) of [PtL2Cl2] (L = pyridine) is estimated as 170 kJ/mol, which gives an average pyridine-Pt bond-dissociation enthalpy of 122 kJ/mol in the gas phase. For other amine ligands, the bond-dissociation enthalpy is less than for the pyridine complex, falling to a min. of 97 kJ/mol for NH3. These imply sublimation heats of 270-300 kJ/mol in the Cl complexes.

Electric Literature of C10H10Cl2N2Pt. 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: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about The effect of complexation with platinum in polyfluorene derivatives: A photo- and electro-luminescence study. Author is Assaka, Andressa M.; Hu, Bin; Mays, Jimmy; Iamazaki, Eduardo T.; Atvars, Teresa D. Z.; Akcelrud, Leni.

The synthesis and characterization of a polymeric structure containing fluorene units statistically linked to 3-cyclohexyl-thiophene and bipyridine PFOTBipy-poly[(4-hexylthiophene-2,5-diyl)(9,9-dihexyl-fluoren-2,7-diyl)-co-(bipyridine-5.5′-diyl)(9,9-dihexyl-fluoren-2,7-diyl)], is reported. The complexation with platinum was possible through the bipyridil units present in 10%, 50% and 100% content. The structure has a fluorenyl moiety between each bipyridine and thiophene groups resulting in a stable and efficient light-emitting polymeric material combining the well known emissive properties of fluorene, the charge mobility generated by thiophene and the electron-transfer properties of a metal complex as well. All the polymers were photo and electroluminescent materials, and showed phosphorescence at low temperatures Photoluminescence properties were studied by steady state and time resolved spectroscopy and showed changes of both emission peak and relative intensity of the emission bands depending on the relative amount of the platinum complex. The electroluminescence followed the trends found for photoluminescence. The blue emission of the copolymer without platinum is due to the fluorenyl segments and for higher complex contents the emission is characteristic of the aggregates involving the bipyridinyl moieties. Therefore, emission color can be tuned by the complex content. The turn-on voltage was strongly reduced from 22 to 8 V for the 100% complexed copolymer, as compared to the device made with the non complexed one, but the luminance decreased, due to quenching or trapping effects.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: cis-Dichlorobis(pyridine)platinum(II)( cas:15227-42-6 ) is researched.Application In Synthesis of cis-Dichlorobis(pyridine)platinum(II).Mattern, I. E.; Cocchiarella, L.; Van Kralingen, C. G.; Lohman, P. H. M. published the article 《Prophage induction and mutagenicity of a series of antitumor platinum(II) and platinum(IV) coordination complexes》 about this compound( cas:15227-42-6 ) in Mutation Research. Keywords: antitumor platinum compound mutagenesis; prophage induction antitumor platinum compound. Let’s learn more about this compound (cas:15227-42-6).

Eleven Pt compounds with N donor ligands (aminocyclopentane, aminocyclohexane, pyridine, etc.), previously tested for antitumor activity, were studied for induction of prophage λ and for mutagenicity in the Ames assay, with various strains of Salmonella. The compounds included cis and trans isomers of Pt(II) and Pt(IV) complexes and were tested with and without metabolic activation. All the cis compounds elicited prophage induction, whereas the trans compounds were inactive. Mutagenicity was found only in strains containing the R factor, indicating that SOS-type repair processes are required for the conversion of initial DNA lesions into mutations. Mutation induction was also influenced by the excision-repair process. The 2 trans compounds were not, or only slightly, mutagenic; all other compounds were mutagenic in at least one strain, exhibited a 2-20-fold increase over the spontaneous background level. Addition of liver homogenate had no significant effect on the number of mutants. One compound induced exclusively frameshift mutations. The other mutagenic compounds induced frameshift mutations as well as base-pair substitutions. Seven compounds were more mutagenic for the repair-proficient than for the repair-deficient strains; only one showed the opposite effect. Apparently, for mutagenicity testing of Pt compounds, repair-proficient strains are more sensitive indicators. The differences in response of the various strains toward the compounds suggest the formation of different DNA lesions and(or) a selective action of repair processes on these lesions. In general, a good qual. correlation was observed between prophage-inducing capacity, mutagenicity in bacterial and mammalian cells and antitumor activity.
