Rhodium(III)-Catalyzed Selective C-H Acetoxylation and Hydroxylation Reactions.

An efficient Cp*Rh(III)-catalyzed, chelation-assisted C(sp2)-H acetoxylation and hydroxylation reaction has been developed for the first time. The reaction proceeds under mild conditions and allows for selective preparation of C-H acetoxylation and hydroxylation products, thus providing a good complement to previous C-H oxygenation reactions and expanding the field of Cp*Rh(III)-catalyzed C-H functionalizations.
