When dimethyl(phenyl)silanol is subjected to an electron-deficient olefin in the presence of a stoichiometric amount of Pd(OAc)2, substitution of the C-H bond of the olefin by a phenyl group on the silanol occurs in 52- 86% yields. The reactions of several aryl- and alkenylsilanols with several olefins are also found to proceed in the system of 10 mol% of Pa(OAc)2, Cu(OAc)2 (3 mol), LiOAc (2 mol) to give the corresponding products in up to 69% yield.
