Abstract
Silica-supported dichlorophosphate had been proved to be an efficient, recoverable and reusable catalyst for Beckmann rearrangement of a variety of ketoximes and dehydration of various aldoximes in THF under microwave irradiation. This protocol has advantages of high conversion, high selectivity, short reaction time, no environmental pollution and simple work-up procedure.
Keywords: Beckmann rearrangement, dehydration, silica-supported dichlorophosphate, oxime
