The reaction of ketoximes with hypervalent iodine reagents was investigated. A combination of PhI(OAc) 2 and BF3·Et2O promoted the Beckmann rearrangement of ketoximes, thus yielding the corresponding amides. From a detailed investigation of the reaction, it was determined that the Beckmann rearrangement is preceded by acetylation of the hydroxy group of the ketoxime in situ, accelerating the Beckmann rearrangement. The acetylated ketoxime undergoes the Beckmann rearrangement with BF3·Et2O was confirmed. The reaction of ketoximes with Koser’s reagent [PhI(OH)OTs] in the presence of THF results in hydrolysis, affording the corresponding ketones in high yields at room temperature
