Photochemical Reactions of Bis(aryl-subsituted Group 14 Element)platinum Complex

摘要

Bis(silyl)- and bis(germyl)platinum(II) complexes are important intermediates in Pt-catalyzed synthetic reactions such as the bis-silylation and bis-germylation of C-C triple and double bonds and dehydrocoupling of group 14 element compounds. These complexes also act as useful starting materials for group 14 element-containing compounds. As a part of our continuous study on group 14 element-transition metal bond, we have studied photochemical reactions of bis(triaryl-substituted group 14 element)platinum(II) complexes, Pt(Ar3E)2(PMe2Ph)2; E = Si, Ar = Ph; E = Ge, Ar = Ph, p-C6H4SiMe3, p-C6H4C(CH3)3; E = Sn, Ar = Ph) by laser flash photolysis and chemical trapping experiments.
