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
