The invention provides a synthetic method for N-substituted imide. According to the method, aromatic ketone and amine are used as substrates, air or oxygen is used as an oxygen source, and cyclic imide is produced under liquid phase conditions under the action of a catalyst. The method is mild in conditions, high in oxidation efficiency and high in product yield; and since the method uses air or oxygen as the oxygen source, the method is economic and environment-friendly and has good application prospect.

Selective oxidative cleavage of a C-C bond offers a straightforward method to functionalize organic skeletons. Reported herein is the oxidative C-C bond cleavage of ketone for C-N bond formation over a cuprous oxide catalyst with molecular oxygen as the oxidant. A wide range of ketones and amines are converted into cyclic imides with moderate to excellent yields. In-depth studies show that both α-C-H and β-C-H bonds adjacent to the carbonyl groups are indispensable for the C-C bond cleavage. DFT calculations indicate the reaction is initiated with the oxidation of the α-C-H bond. Amines lower the activation energy of the C-C bond cleavage, and thus promote the reaction. New insight into the C-C bond cleavage mechanism is presented.
