Summa'ry. Oligoether residues with terminal 8-quinolyl donor groups have been loaded virtually quantitatively onto polystyrene resin supports and function more effectively than dibenzo-18-crown-6 as solid/liquid phase transfer catalysts in Williamson ether syntheses. Oligoethylene oxide species are

Spacer-modified polymer supports have been synthesized through the polymeric Grignard reagent method. Phosphonium-active sites were then introduced into these supports and the polymer-supported phosphonium salts were used as phase transfer catalysts for the nucleophilic substitution reactions. lnflu
