Synthesis of imides
A direct coupling of NH-amides with methylarenes under iodine/aqueous TBHP conditions enables a metal-free synthesis of imides. The optimized conditions worked also very well with benzaldehydes and benzyl alcohol and furnished the corresponding imides in good to excellent yields.
