使用四种路易斯酸在 17 种不同的离子液体中进行五种酮肟的贝克曼重排。比较和讨论了离子液体中阳离子类型和阴离子类型对重排反应速率和产物组成的影响。研究了离子液体的疏水性和氢键能力对酮肟重排的影响以及路易斯酸的催化活性。
The Beckmann rearrangement of five ketoximes was done in 17 different ionic liquids by using four Lewis acids. The effect of the type of cation and the type of anion in the ionic liquid on the rate of the rearrangement reaction and product composition is compared and discussed. The effects of the hydrophobicity and the hydrogen bonding ability of ionic liquids on the rearrangement of ketoximes were investigated, as well as the catalytical activity of the Lewis acids.
