a one-pot procedure under mild conditions. The structure of 3a was unambiguously confirmed by X-ray single crystal diffraction and it was an active catalyst in the Buchwald-Hartwig amination and α-arylation of ketones even at very lowcatalystloadings (0.01 mol%).

An easily available NHC-Pd(II)-Im (NHC = N-heterocyclic carbene, Im = 1-methylimidazole) complex was found to be an efficient catalyst for the α-arylation reaction between ketones and aryl chlorides. Under the optimal conditions, all reactions proceeded smoothly to give the desired products in good to high yields within hours.

synthesized and unambiguously confirmed by X-ray single crystal diffraction. It was found to be an efficient and air-stable catalyst for the α-arylation of ketones. The reaction could be operated in air without any negative effect. Non-activated aryl and heteroaryl chlorides have been successfully applied in the reaction with only 0.5 mol% catalyst loadings under air atmosphere. Excellent to good product yields
