Reductive debromination of a-bromo carbonyl compounds with di-Bu telluride is described. Debromination was greatly enhanced by organic bases such as Et3N, or pyridine and the reaction in acetonitrile might occur even at room temperature Thus, reaction of RCOCH2Br(R = Ph, p-BrC6H4, 2-furyl, 2-thienyl, Me) with Bu2Te in presence of Et3N gave 86-92% RCOMe.
