开发了固定在 Dowex 树脂上的 β-环糊精作为高效固-液相转移催化剂的催化活性，用于在水中合成烷基硫氰酸酯和苯甲酰衍生物。亲核取代反应在温和的反应条件下进行，并以优异的产率得到产物。此外，催化剂可以通过轻松分离进行回收，而不会损失任何活性。
The catalytic activity of beta-cyclodextrin immobilized on Dowex resin as an efficient solid-liquid phase transfer catalyst was developed for the synthesis of alkyl thiocyanates and phenacyl derivatives in water. The nucleophilic substitution reactions were performed under mild reaction condition and gave the products in excellent yields. Furthermore, the catalyst could be recycled by facile separation without any loss of activity.
