Lu, Hui-Yang published the artcileN-heterocyclic carbene-palladium-imine complex catalyzed α-arylation of ketones with aryl and heteroaryl chlorides under air atmosphere, Recommanded Product: 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride, the publication is Tetrahedron Letters (2020), 61(29), 152124, database is CAplus.
A new structure of saturated ring skeleton monoligated NHC-Pd-imine complex was easily 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 was operated in air without any neg. effect. Non-activated aryl and heteroaryl chlorides were successfully applied in the reaction with only 0.5 mol% catalyst loadings under air atm. Excellent to good product yields were afforded.
