Imides are prepared conveniently by visible-light-driven oxidations of various N -alkylamides under mild conditions. The majority of the reactions proceed efficiently by using Oxone as the oxidant in the presence of a catalytic amount of KBr in H 2 O/CH 2 Cl 2 under irradiation by an 8 W white LED at room temperature. Experimental studies suggest that an imine, obtained from the substrate amide via a radical process, is the key intermediate.
N-Butylammonium carboxylates/Tf2O: Ionic liquid based systems for the synthesis of unsymmetrical imides via a Ritter-type reaction

experimental part, p. 2881 - 2884 (2012/07/28)
We have developed a new method for the preparation of unsymmetrical imides using liquid carboxylate salts via a Ritter-type process. The reactions were carried out with nitriles and n-butylammonium carboxylates as ionic liquids in the presence of triflic anhydride (Tf2O) as the promoter. Mild reaction conditions, simplicity of the procedure, and proton-free conditions are the main advantages of this procedure.
Highly efficient copper-catalyzed amidation of aldehydes by C-H activation

experimental part, p. 10722 - 10726 (2009/12/03)
We have developed a highly efficient method for the copper-catalyzed amidation of aldehydes in the presence of N-bromosuccinimide (NBS). This method is simple, economical, and has practical advantages for synthesis of imides.
