carbocyanation of non-polarized trisubstituted olefins 1 has been achieved by employing chlorinated cyanides 2 as starting materials. The present reaction gives the carbocyanated product 3 through radical-based 1,3-transfer of CN. Consequently, two different carbon units, cyano and chlorocyanomethyl groups, are introduced into the highly substituted olefins, generating consecutive quaternary and tertiary
