5-6-η-Cyclooctadiene)(1-6-η-cyclooctatriene)ruthenium catalyzes the silylation of olefins at 60–140 °C to give allylsilanes with good selectivity in high yields. The reactions of trialkylsilane with 2-methyl-1-butene, 2-methyl-2-butene, and 3-methyl-1-butene give the same product, 3-methyl-1-trialkylsilyl-2-butene. Silylation of ethyl (E)-2-butenoate gives ethyl (E)-4-trialkylsilyl-2-butenoate in high yield.
