Abstract

Nickel-catalyzed intermolecular benzylation and heterobenzylation of unactivated alkenes with benzyl chlorides provides functionalized allylbenzene derivatives. In contrast to analogous palladium-catalyzed processes, all reactions described herein employ electronically unbiased aliphatic olefins (including ethylene), proceed at room temperature, and provide 1,1-disubstituted olefins with very high selectivity.
