The mixed copper, zincbenzylicorganometallics 1a–1c react efficiently with various electrophiles. By the reaction with acyl chlorides, highly functionalized 2-substituted indoles are produced. The treatment of 1a with allylic bromides, 3-iodo-cyclohexenone and ethyl propiolate furnishes polyfunctionalized anilines. Several of them could be converted into five- or seven-membered heterocycles.
