The reaction which proceeds with Bronsted acid or a Lewis acid catalyst efficiently, for example, the benzoylation reaction of alcohol is also made easy, and also the point of toxicity, environment, etc. which makes recovery and reuse of a catalyst easy. It is to provide an excellent solid acid catalyst. Arylbis (perfluoroalkylsulphur) represented by general formula [1] (In formula [1], R < 1> represents a substituted or unsubstituted aryl group, Rf < 1> and Rf < 2> represents a perfluoroalkyl group independently from each other.). Phenyl) methane, for example, the para position of pentafluorophenylbis (perfluoroalkylsulfonyl) methane is supported on a polystyrene resin, and in general formula [3] (in formula [3], R 3 is substituted or unsubstituted). The arylene group of the ring, Rf 1 and Rf 2 are the same as above). Polystyrene supported arylbis (perfluoroalkylsulfonyl) methane is obtained.n n n n n n n n n n n n n Arylbis (perfluoroalkylsulfonyl) methane |
