摘要
报道不同路易斯酸性催化剂作用下二苯甲酮肟的Beckmann重排反应的结果,即分别以PC l5、H2SO4、HC l-Ac2O、H2SO4-Ac2O、H3PO4-Ac2O、PPA、HC l-Ac2O-AcOH为催化剂进行比较实验.发现H3PO4-Ac2O是二苯甲酮肟进行Beckmann重排反应的理想催化剂之一.
The Beckmann rearrangement reactions of diphenyl -methanone oxime in the presence of different Lewis acid catalyst such as PCl5 , H2SO4 , HCl - Ac2O, H2SO4 - Ac2O, H3PO4 - Ac2O, PPA and HCl -Ac2O -AcOH were studied. The result suggested that HBPO4 -Ac2O was an effective and suitable catalyst of the Beckmann rearrangement reaction of diphenyl-methanone oxime.
