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.Name: cis-Dichlorobis(pyridine)platinum(II).Lasitsa, N. A.; Skvortsov, N. K.; Lobadyuk, V. I.; Spevak, V. N.; Esina, G. A.; Abramova, I. P.; Lazarev, S. Ya. published the article 《Platinum(II) complexes in the catalytic hydrosilylation of acetophenone. Kinetics of the reaction and the effect of ligands》 about this compound( cas:15227-42-6 ) in Zhurnal Obshchei Khimii. Keywords: acetophenone hydrosilylation platinum catalyst kinetics; ligand effect platinum catalyst hydrosilylation. Let’s learn more about this compound (cas:15227-42-6).
A kinetic study of hydrosilylation of MeCOPh with MeSiHCl2 or MeSiPhH2 in the presence of LL1PtX2 (X = Cl, Br; L = L1 = Me2SO, Et2SO, py, Et3P, MeSOC6H4Me-4; L = C2H4, L1 = Me2SO, Et2SO; L = py, L1 = Et2SO; L = MeSOC6H4Me-4, L1 = Bu3P) catalysts showed a relationship between the ligand type and catalytic activity. In contrast with bis(phosphine) and bis(olefin) complexes, bis(sulfoxide) complexes and all complexes with mixed ligands, one of which is sulfoxide, show high catalytic activity. For the reaction with MeSiHCl2, the order of reactivity is olefin > SO > P(III) > py, close to an analogous relationship for the hydrosilylation of olefins.
