The facile one-pot synthesis of N-imidoylbenzotriazoles via a Beckmann rearrangement of ketoximes

Abstract N -Imidoylbenzotriazoles 2a – m were obtained in good to excellent yields (up to 97%) by the reaction of ketoximes 1a – m with MsCl and subsequently with benzotriazole as a one-pot process in Toluene/CH 3 CN at reflux temperature via a Beckmann rearrangement.
