A new arylamination protocol for mild amination of aryl chloride has been developed by using polymer supported N-heterocyclic carbene(NHC)-Ni(0) complex. Poly(1-methylimidazoliummethyl styrene)-surface grafted-poly(styrene) resin was prepared by suspension polymerization for the first time as a polymer supported NHC precursor, and used for Ni(0) ligand. To prepare this polymer-supported NHC, 1-methyl-3-(4-vinylbenzyl)imidazolium hexafluorophosphate, [MVBIM][PF6-], was synthesized as a comonomer and copolymerized with styrene and DVB in water. Using this catalyst, aryl and heteroaryl chlorides react with secondary amines and anilines was attained within hours with high efficiency. |
