A flexible metal-free cascade reactioninvolving aerobic C(sp3)–H hydroxylation and decarbonylation with high regioselectivity and functional group tolerance has been established. Moreover, this indirect hydroxylation approach of N-aryl amides could enable the construction of a wide range of valuable secondary alcohols at α-position of N-aryl amides. It provides a supplementary strategy for direct
