A series of cis-alkynyl(silyl)platinum(II) complexes, cis-Pt(C≡CAr)(SiAr′3)(PMe2Ph)2 (2: Ar = Ph, 4-MeOC6H4, 4-MeC6H4, 4-ClC6H4, 4-BrC6H4, 4-NCC 6H4; Ar′ = Ph, 4-MeOC6H4, 4-MeC6H4, 4-CF3C6H4), have been prepared, and their thermolysis reactions in solution have been examined. Complexes 2 smoothly undergo C-Si reductive elimination in benzene-d6 at around 35 °C to give the corresponding platinum(O) complexes coordinated with silylacetylenes, Pt(ArC≡CSiAr′ 3)(PMe2Ph)2 (3). Kinetic examinations suggest a concerted reaction process that is operative directly from the four-coordinate complexes. The more electron-donating substituents on the Ar and Ar′ groups provide higher reductive elimination rates.
