2-Trimethylsilylalk-2-enylstannanes undergo tin(IV) chloride promoted reactions with aldehydes to give homoallylic alcohols with retention of the 2-trimethylsilyl group. 4-Alkoxy-2-trimethylsilylalk-2-enyl(tributyl)stannane 31 reacts with aldehydes under these conditions with excellent stereoselectivity in favour of the 1,5-syn-(E)-products 32 – 35. Preliminary studies into the chemistry of these vinylsilanes
