Palladium-Catalyzed Regioselective C-H Bond Acetoxylation-Alkoxylation of Azoxybenzenes

Efficient strategies for the regioselective ortho acetoxylation/alkoxylation of C-H bond of azoxybenzenes in the presence of palladium catalysts were developed using PhI(OAc)(2) as the teminal oxidant. Under the very similar conditions established, both reactions proceeded smoothly and were tolerated by a variety of functional groups.
