Dehydrogenative silylation of olefins, such as styrenes, methyl acrylate, a
nd vinyl ether, using allyltriethoxysilane as the source of the silyl group
can be catalyzed by RuHCl(CO)(PPh3)(3) to give the corresponding vinylsila
nes in good to excellent yields. The ruthenium complex also catalyzed the s
elf-dehydrogenative silylation of allylsilanes, yielding 1,3-bis(triorganos
ilyl)propenes.
