Immobilized N-alkylaminopyridinium salts on divinylbenzene crosslinked polystyrene gel was reusable at least 8 times on the reaction of 4-chloronitrobenzene with anhydrous potassium fluoride in tetrahydrothiophene 1,1-dioxide to give 4-fluoronitrobenzene in high yield.The immobilized catalyst was also successfully used for a synthesis of several aryl fluorides in good yields.
