Rhodium-Catalyzed ortho-Benzoxylation of sp2 C−H Bond
摘要:
A rhodium-catalyzed ortho-benzoxylation of the sp(2) C-H bond by carboxylic acids Is described. The procedure tolerates carbomethoxy, formyl, bromo, chloro, and nitro groups, providing the benzoxylated products in moderate to good yields. Importantly, no external oxidant was required for the transformation.
