Metal Salt Catalyzed Carbenoids-XV. The Synthetic And Structural Aspects Of Copper Salt Catalyzed Additions Of Bis-methoxycarbonyl Carbene To Olefins
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 C-H insertion products which could formally be derived from allylic radical or ionic intermediates. Cyclopropanation with cis 2-heptene proceeds 5.20 times as fast as with the trans isomer and cyclohexene reacts 4.90 times faster than 1-methyl cyclohexene when the catalyst is iodo(trimethyl phosphite)copper(I). © 1976.
