摘要：

The catalytic substitution at silicon occurs in the reaction of toluene and diethylsilane in the presence of KNH2 loaded on alumina, the yield of benzyldiethylsilane being 85% in 40 h at 329 K. Benzene also reacted with diethylsilane in the presence of the catalyst to afford a 7.5% yield of benzyldiethysilane in 20 h at 329 K.
