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
Soluble polymeric phase transfer catalysts (PTCs) containing benzyltributylphosphonium chloride moieties and polar N,N-dialkyl-acrylamide with long alkyl groups such as N,Ndipropylacrylamide, N,N-dibutylacrylamide, N,N-dihexylacrylamide, and N,N-dioctylacrylamide were prepared via two-step reactions
Poly[N-(2-aminoethyl )acrylamido]trimethyl ammonium chloride resin was developed as a new polymeric phase-transfer catalyst. This quaternized polyacrylamide-catalyzed the regioselective ring opening of epoxides by azide ion to give azidohydrins in high yield under mild conditions.
