A Co-catalyzed effective synthesis of N-sulfonylcarboxamides from the reaction of carboxylic acids and organic azides in the presence of isocyanide has been developed. The protocol has the advantages of short time, low temperature, and being oxidant-free, which provides a new and simple approach for the synthesis of N-sulfonylcarboxamides in good to excellent yields with a broad substrate scope.

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 yield.
