Abstract

Abstract The transylidation reactions of PhSeBr with two equivalents of an alkylidene- triphenylphosphorane give selenophosphoranes, Ph 3 P CRSePh. These also can be obtained by treating the corresponding selenophosphonium salts, prepared by quarternization of triphenylphosphine with PhSeCHRBr, with n-BuLi. The selenophosphoranes react with aldehydes in situ (Wittig reaction) to give the expected ...
