O-Benzenedisulfonimide as a reusable broonsted acid catalyst for hosomi-sakurai reactions

Article abstract of DOI:10.1055/s-0029-1217093

Various acetals or alcohols react with allyl(trimethyl)silane or 1-phenyl-2-(trimethylsilyl)acetylene in the presence of a catalytic amount of the Bronsted acid o-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. Georg Thieme Verlag Stuttgart.
