Abstract

The treatment of 4-benzyloxy-1-butyne with PhMe<sub>2</sub>SiMgMe in the presence of a catalytic amount of MnCl<sub>2</sub> gave a monosilylated product, (<i>E</i>)-PhCH<sub>2</sub>OCH<sub>2</sub>CH<sub>2</sub>CH=CHSiMe<sub>2</sub>Ph, selectively after an aqueous workup. Meanwhile, the reaction of isoprene with PhMe<sub>2</sub>SiMgMe under manganese catalysis and the subsequent addition of iodomethane afforded 4-dimethylphenylsilyl-2,3-dimethyl-1-butene in good yield.
