Hypervalent Iodine in SYnthesis XXXIII: Palladium-Catalyzed Cross-Coupling Reaction of Potassium Aryltrifluoroborates with Diaryliodonium Salts and Hydroxy(tosyloxy)iodobenzene

摘要

Potassium aryltrifluoroborates react smoothly with diaryliodonium salts and hydroxy(tosyloxy)iodobenzene, PhI(OH)OTs, under mild conditions in the presence of a palladium catalyst and without added base to afford biaryls in excellent yields.
