Abstract
Various acetals or alcohols react with allyl(trimethyl)silane or 1-phenyl-2-(trimethylsilyl)acetylene in the presence of a catalytic amount of the Brønsted acid o-benzenedisulfonimide under mild conditions to give good yields of the allylated products. The catalyst can be easily recovered and purified for use in further reactions.
