A simple and efficient method for the synthesis of substituted sulfoxonium ylides from diazocompounds in dimethyl sulfoxide was developed. It is notable that the reaction employs cheap and harmless copper(I) bromide as catalyst. Moreover, the mild reaction system and a wide range of substrates with high yields make the protocol very practical.

Key words: CuBr, diazocompounds, dimethyl sulfoxide, sulfoxonium ylides
