nBu4NI-Catalyzed oxidative imidation of ketones and imides for the synthesis of alpha-amino ketones were realized for the first time. The methodology is characterized by its wide substrate scope even for acetone with readily available phthalimide, saccharin and succinimide, which opens a new pathway for direct imidation of ketones.
oxidative C–H bond amidation of anilides with dibenzenesulfonimides mediated by PhI(OAc)2 under metal-free conditions provided para-amidated anilides with high selectivity and moderate to good yields. The reaction proceeded under mild or neutral conditions and it has good air and moisture tolerance. The method represents a novel and facile strategy for the synthesis of arylamines.
