We present a metal-free method for the synthesis of imides by the direct coupling of NH-amides with methylarenes under iodine/aqueous TBHP conditions. The optimized conditions worked very well with benzaldehydes and benzyl alcohol and furnished the corresponding imides in good to excellent yields. A series of control and radical scavenger experiments were also performed, which suggested the involvement

A new protocol for the synthesis of imides has been developed. In the presence of copper catalyst, N‐benzylamides were oxidized to the corresponding imides by TBHP/TEMPO system in moderate to good yields.
Photooxidation of several mesoionic compounds gave ring cleavage products, some of which were apparently formed via the endoperoxides of the mesoionicrings. Photooxidation of a Δ2-oxazolin-4-one and a Δ2-thiazolin-4-one gave the corresponding 4,4′-bisoxa- and bisthiazolinone in dichloromethane, whereas the former gave benzamide in dimethylformamide.

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 aminehydrochloridesalts to provide imides in moderate to good yields. A possible reaction pathway for the formation of the products is also discussed in this paper.
