Addition of excess diethylsulfide to the Karstedt catalyst prevents agglomeration of Pt and results in higher reaction rates for hydrosilylation of olefins. The beneficial effects were very pronounced in the hydrosilylation of trimethylsilyl-4-pentenoate with tetrakis(dimethylsilylethyl)silane, where 57% yield was obtained compared with 10% without diethylsulfide. Enhanced activity was also observed in the hydrosilylation of tetravinylsilane, vinyltrimethylsilane, and 1-hexene with chlorodimethylsilane.
