A rhodium-catalyzed redox-neutral reaction of arylhydrazines with sulfoxonium ylides to construct 2-arylindole derivatives in one pot has been developed. The transformation proceeds efficiently under mild conditions and involves tandem C-H activation and an intramolecular dehydration annulation sequence, providing a straightforward pathway to access pharmaceutically and biologically valuable 1-aminoindole

An efficient Rh(III)-catalyzed synthesis of 2-arylindole derivatives via intermolecular C–H annulation of arylhydrazines with sulfoxonium ylides was accomplished. A variety of 2-acetyl-1-arylhydrazines with sulfoxonium ylides were converted into 2-arylindoles in satisfactory yields. Excellent selectivity and good functional group tolerance of this transformation were also observed.
