Hydrosilylation chemistry and catalysis with cis-PtCl/sub 2/(PhCH=CH/sub 2/)/sub 2/
The precursor cis-PtCl/sub 2/(PhCH=CH/sub 2/)/sub 2/ is shown to catalyze (i) the hydrosilylation of various terminal olefins and acetylenes, (ii) the reduction of carbonyl functions with silanes in the presence of pyridine or aniline as cocatalyst, and (iii) the formation of R/sup 1//sub 3/SiOR/sup 2/ from R/sup 1//sub 3/SiH and R/sup 2/OH. The hydrosilylation of styrene is shown to proceed via reduction of PtCl/sub 2/(PhCH=CH)/sub 2/ to Pt(PhCH=CH/sub 2/)/sub 3/ with concomitant formation of 2 equiv of R/sub 3/SiCl and 1 equiv of PhCH/sub 2/CH/sub 3/. Extensive /sup 195/Pt measurements together with /sup 13/C studies on complexed styrene selectively enriched at the ..beta..-carbon support the formation of the Pt(O) complex. The precursor cis-PtCl/sub 2/(PhCH=CH/sub 2/)/sub 2/ is suggested to arise from the trans isomer which is identified by /sup 195/Pt NMR and its reaction chemistry.
