Terminal epoxides react with 2-(trialkylsilyl)allyl organometallics (Sn, Si, Li, Cu) with varying degrees of efficiency depending upon the nature of the epoxide. The combination of [2-(trimethylsilyl)allyl]tributylstannane (4) and EtAlCl(2) is optimum and provides 1-substituted 4-(trimethylsilyl)-4-penten-1-ol products in good yield.
