A simple, new preparation of α,α-dimethylallyltrimethylsilane: a useful prenylation reagent

Abstract

Starting from 3-methylbut-1-yn-3-ol, a short synthesis of αα-dimethylallyltrimethylsilane (a selective prenylation reagent) has been achieved in 47% overall yield; several other unsaturated organosilicon intermediates of wide potential utility in organic synthesis are also prepared.
