Abstract

Mixed homocuprates [(MeSOCHzCuR) Li] and [(MeSOCH, CuR) Li (LiCN)] in which the anion of dimethyl sulfoxide acts as a nontransferable ligand are readily prepared from MeSOCH2Li, alkyl-or aryllithium reagents, and Cu (I) salts. These novel cuprates are useful in the conversions of acid chlorides to ketones, conjugate additions to a, &unsaturated ketones, h2'reactions with allylic or propargylic acetates and epoxides, and coupling ...
