Abstract Cp*Co(III)-catalyzed direct C H amidation of azines has been developed. This conversion could proceed smoothly in the absence of external oxidants, acids or bases, with excellent regioselectivity and broad functional group tolerance. CO2 was released as the sole byproduct, thus providing an environmentally benign amidation process. The products obtained are important intermediates in organic

Rh(III)-catalyzed synthesis of vicinal diamides has been realized via elaboration of an authenticated Rh–C(sp3) species generated via initial intramolecular amidorhodation of olefins. The second amidation was achieved using both electrophilic and nucleophilic amidating reagents. The reactions proceeded under mild conditions with good yield, broad substrate scope, and excellent functional-group tolerance
RhIII‐catalyzedC−H functionalization reaction yielding isoindolinones from arylhydroxamates and ortho‐substituted styrenes is reported. The reaction proceeds smoothly under mild conditions at room temperature, and tolerates a range of functional groups. Experimental and computational investigations support that the high regioselectivity observed for these substrates results from the presence of an
