The complexes cis-Pt(CH=CH2)(SiR3)(PMe 2Ph)2 (SiR3 = SiPh3 (3a), Si(C 6H4Me-p)3 (3b), Si(C6H 4OMe-p)3 (3c), SiMePh2 (3d), SiFPh2 (3e)) have been prepared by the reactions of trans-PtCl(SiR3) (PMe2Ph)2 with Mg(CH=CH2)2 in THF, followed by trans-cis isomerization of the resulting trans-alkenyl(silyl) complexes in solution promoted by CO. Complexes 3a-e undergo C-Si reductive elimination in toluene-d8 to give platinum(0) complexes coordinated with vinylsilanes. Kinetic data have suggested a direct reaction path without dissociation of the phosphine ligand.
