Abstract

Abstract : The Friedel–Crafts alkylation strategy was used to prepare a hypercrosslinked polymer catalyst, which showed superior performance towards the cycloaddition reaction of CO2 with epoxides. Abstract : Quaternary phosphine type hypercrosslinked polymer catalysts were successfully prepared using the Friedel–Crafts alkylation reactions, which benefit from the synergistic effects between the Brønsted acidity of the hydroxyl group and nucleophilicity of the Br − group as well as the CO2 capture of the ionic liquids. The as-obtained metal-free catalysts facilitate the cycloaddition and synthesis of high value-added fine chemicals.
