Abstract

Abstract: Polymer-supported crown ethers 1 and 2 were prepared by reaction of 1% cross- linked chloromethylated polystyrene, with (hydroxymethy1)-and (w-hydroxynony1)-18-crown- 6, respectively. Their phase-transfer catalytic activity was tested in anion-promoted nucleophilic aliphatic substitutions and compared with that of structurally similar soluble crown ethers and of polymer-supported and soluble phosphonium salts. Catalytic ...
