[CNN]-pincer nickel(ii) complexes of N-heterocyclic carbene (NHC): synthesis and catalysis of the Kumada reaction of unactivated C–Cl bonds†
Abstract
Three novel [CNN]-pincer nickel(II) complexes with NHC-amine arms were synthesized in three steps. Complex 5b was proven to be an efficient catalyst for the Kumada coupling of aryl chlorides or aryl dichlorides under mild conditions.
