secondary C-Hbonds, which are adjacent to an oxygen or nitrogen atom on one side, and benzylic or adjacent to a carbonyl group on the other side. A variety of valuable fused heterocycles were obtained from easily accessible ortho-bromophenol and aniline precursors. The second C-H bond cleavage was successfully replaced with carbonyl insertion to generate other types of C(sp3 )-C(sp3 ) bonds.
