Abstract
Hydrosilation of alpha,beta-unsaturated carbonyl compounds catalyzed b y hydridotetrakis(triphenylphosphine)rhodium(I) (1) was found to be hi ghly regioselective, depending on the silanes used. Diphenylsilane was found to give 1,2-hydrosilation, whereas dimethylphenylsilane and oth er monohydrosilanes gave 1,4-addition. The kinetic isotope effect of t he hydrosilation reaction was examined, and a mechanism was proposed t o account for the regioselection and the kinetic isotope effect.
