Monovalent Nickel Complex Bearing a Bulky N-Heterocyclic Carbene Catalyzes Buchwald–Hartwig Amination of Aryl Halides under Mild Conditions

Abstract Monovalent nickel complex bearing a bulky N-heterocyclic carbene (NHC) and triphenylphosphine was synthesized and demonstrated to catalyze the Buchwald–Hartwig amination of aryl halides with diarylamines to form triarylamines under mild conditions.
