Synthesis of Polyacrylonitrile Fiber-Supported Poly(ammonium methanesulfonate)s as Active and Recyclable Heterogeneous Brønsted Acid Catalysts

A new polyacrylonitrile fiber‐supported Brønsted acid catalyst has been developed and verified to efficiently (high yield, 10 cycles) mediate Biginelli reactions in ethanol, Pechmann condensations in toluene, Friedel–Crafts alkylations of indoles in water and conversion of fructose in dimethyl sulfo...

Description
Summary:A new polyacrylonitrile fiber‐supported Brønsted acid catalyst has been developed and verified to efficiently (high yield, 10 cycles) mediate Biginelli reactions in ethanol, Pechmann condensations in toluene, Friedel–Crafts alkylations of indoles in water and conversion of fructose in dimethyl sulfoxide (DMSO) and mixed‐aqueous system.
