Palladium(II)-Catalyzed othro-C-H-Benzoxylation of 2-Arylpyridines by Oxidative Coupling with Aryl Acylperoxides

A palladium(II)-catalyzed ortho-benzoxylation of 2-arylpyridines with aryl acylperoxides was developed. With pyridyl as directing group, the benzoxylation reaction exhibits remarkable regioselectivity and excellent functional group tolerance, providing the products in up to 87% yield.
