Abstract: Lithium and bis (triphenylphosphorany1idene) ammonium salts of bis (1, 2- benzenediolato) allylsilicates, which were prepared via the reactions of allyl-, prenyl-, and (E)-and (2)-crotyltrichlorosilanes with dilithium catecholate, were found to react with aromatic aldehydes chemoselectively to give the corresponding homoallyl alcohols in a regiospecific and highly diastereoselective manner in high yields. The unique reaction modes including ...
