β-环糊精选择性催化合成邻羟基苯乙酮
Synthesis of 2-Hydroxy-acetophenone by β-Cyclodextrin Selective Catalysis
【摘要】 利用β-环糊精对底物的包络作用,经由Fries重排反应选择性合成了邻羟基苯乙酮。实验结果表明,加入β-环糊精能够提高重排反应的选择性,使邻羟基苯乙酮收率达到44.6%。
【Abstract】 Using the inclusion action of β-Cyclodextrin with phenyl acetate,2-Hydroxy-acetophenone was Synthesized via Fries rearrangement reaction.The results indicated that it could improve the selectivity of Fries rearrangement reaction by adding β-Cyclodextrin.The yield of the ortho-product reached 44.6%.
