Rhodium(III)-catalyzed azacycle-directed intermolecular insertion of arene C-H bonds into α-diazocarbonyl compounds.

Cp*Rh(III)-catalyzed intermolecular C-C couplings between activated α-diazocarbonyl compounds and arenes bearing a range of azacyclic directing groups have been achieved. This catalytic alkylation reaction operates under mild conditions with good functional group tolerance.
