  3-diiminoindolines in good to high yields with short reaction times. Cu-catalyzed electrophilic addition and ring-opening/rearrangement steps were proposed as being involved in this donor-acceptor metallo carbenoid formation reaction with benzo[c]isoxazoles. Furthermore, under Pd-catalyzed hydrogenation conditions, the resulting products could be transformed into 2,3-diaminoindoles in moderate to high yields

  towards construction of amide C–N bonds under mild conditions through rhodium(III) catalysis has been explored. Previous waste-free amidations were generally limited to the condensation of carboxylic acids and amines. In this report, we directly applied amination of the aldehyde C(sp2)–H bond to extend the scope of amidation reactions. The amination shows a wide substrates scope, and several important
