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

The direct oxidative N-acylation reaction of primary amides with aryl/α,β-unsaturated aldehydes was achieved in the presence of azolium salt C3 and an inorganic base using 3,3′,5,5′-tetra-tert-butyldiphenoquinone as the oxidant, thus providing an efficient approach for the synthesis of three types of imide compounds including N-sulfonylcarboxamides, N-sulfinylcarboxamides, and dicarboxyimides in good
A novel and efficient palladium-catalyzed aminocarbonylation of aryliodides with amides and N-alkyl anilines has been developed. The reaction tolerates a wide range of functional groups and is a reliable method for the rapid synthesis of a variety of valuable imides and tertiary benzanilides under an atmospheric pressure of CO.
