A novel vanadium-catalyzed one-pot domino reaction of 1,2-diketones with amidines has been identified that enables their transformation into imides and amides. The reaction proceeds by dual acylation of amidines via oxidative C(CO)-C(CO) bond cleavage of 1,2-diketones to afford N,N′-diaroyl-N-arylbenzamidine intermediates. In the reaction, these intermediates are easily hydrolyzed into imides and amides through vanadium catalysis. This method provides a practical, simple, and mild synthetic approach to access a variety of imides as well as amides in high yields. Moreover, one-step construction of imide and amide bonds with a long-chain alkyl group is an attractive feature of this protocol.

An efficient approach to imides has been developed. With tert-butyl hydroperoxide (TBHP) as the oxidant, CuBr (20 mol-%) as the catalyst, and PhI(OAc)2 (50 mol-%) as the additive, aldehydes or alcohols reacted with amine hydrochloride salts to provide imides in moderate to good yields. A possible reaction pathway for the formation of the products is also discussed in this paper.
