Abstract

Experimental and structural details are presented for the addition of bis-methoxycarbonyl carbene to a number of olefins employing homogeneous and heterogeneous catalyzed decompositions of dimethyl diazomalonate by copper and silver salts. The cyclopropanations are stereospecific and are accompanied by appreciable amounts of allylic CH insertion products which could formally be derived from allylic radical or ionic ...
