Abstract:The catalytic activity of β‐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.
Keywords:heterogeneous catalyst  β  ‐cyclodextrin  immobilization  nucleophilic substitution  alkyl thiocyanate  phenacyl derivatives
