The present invention provides a solid acid catalyst thatnis excellent from the point of toxicity, environment and others,nwherein reaction can be progressed effectively with Bronstednacid or Lewis acid catalyst. For example, the benzoylationnreaction of alcohol can also be progressed easily, and further,nthe catalyst can be recovered and recycled easily. The paranposition of arylbis(perfluoroalkylsulfonyl)methanenrepresented by the general formula [1] (wherein R 1 shows ansubstituted or unsubstituted aryl group, Rf 1 and Rf 2 arenindependent to each other and show a perfluoroalkyl group), anpentafluorophenylbis(perfluoroalkylsulfonyl)methane, fornexample, is supported on a polystyrene resin, and anpolystyrene-supported narylbis(perfluoroalkylsulfonyl)methane represented by thengeneral formula [3] (wherein R 3 shows a substituted ornunsubstituted arylene group, Rf 1 and Rf 2 are the same as describednabove) is obtained. n(Chemical formula 1)n n(Chemical formula 2) |
