Using Fe3(CO)12 as the catalyst, the reaction of styrenes (C6H5CHCH2, p-CH3C6H4CHCH2, p- ClC6H4CHCH2, and p-CH3OC6H4CHCH2) with triethyisilane gave (E)-β-(triethylsilyl)styrenes (2a, (E)-C6H5CHCHSiEt3; 2b, (E)-p-CH3C6H4CHCHSiEt3; 2c, (E)-p-ClC 6H4CHCHSiEt3; 2d, (E)-p-CH3OC6H4CHCHSiEt3) in 66-89% yields with complete selectivity. Similarly, Fe2(CO)9 also catalyzed dehydrogenative silylation again, with complete selectivity but in low yields. The reaction of styrene with treithylsilane, catalysed by OS3(CO)12, gave a mixture of the corresponding vinylsilane (dehydrogenative silylation product) and alkylsilane (hydrosilylation product).
