The 1-magnesia- and 1-lithia-zincaalkenes of and give a trans-metallation reaction with copper cynide to the corresponding 1-zinca-cyanocurprates and . These new organometallics reacts with various alkylating or allylating agents to give gen-bis-alkylated or gem-bis-allylated compounds in good to excellent yields. By reaction with the acyl chlorides the reagents and allow a new regiospecific synthesis
