lene in the presence of a catalytic amount of the Brønstedacido-benzenedisulfonimide under mild conditions to give good yields of the corresponding products. The catalyst can be easily recovered and purified for use in further reactions, which has economic and ecological advantages. homogeneous catalysis - Brønstedacid - Hosomi-Sakurai reaction - acetals - alcohols
