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

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/CH3CN at reflux temperature via a Beckmann rearrangement.
