Rhodium(III)-Catalyzed Acylation of C(sp3)–H Bonds with Cyclopropenones

Rhodium(III)-Catalyzed Acylation of C(sp3)–H Bonds with Cyclopropenones

Rh(III)-catalyzed activation and acylation of sp3 C–H bonds has been realized with diarylcyclopropenone as an acylating reagent. Both benzylic C–H in 8-methylquinolines and unactivated C–H in 2-alkylpyridines are applicable in this C–H acylation reaction, providing enones in good yields under redox-neutral conditions.
