摘要：
The present invention provides a solid acid catalyst that is excellent from the point of toxicity, environment and others, wherein reaction can be progressed effectively with Bronsted acid or Lewis acid catalyst. For example, the benzoylation reaction of alcohol can also be progressed easily, and further, the catalyst can be recovered and recycled easily. The para position of arylbis(perfluoroalkylsulfonyl)methane represented by the general formula null1null (wherein R1 shows a substituted or unsubstituted aryl group, Rf1 and Rf2 are independent to each other and show a perfluoroalkyl group), a pentafluorophenylbis(perfluoroalkylsulfonyl)methane, for example, is supported on a polystyrene resin, and a polystyrene-supported arylbis(perfluoroalkylsulfonyl)methane represented by the general formula null3null (wherein R3 shows a substituted or unsubstituted arylene group, Rf1 and Rf2 are the same as described above) is obtained. 1 2
摘要（中）：
本发明提供从毒性，环境等方面优异的固体酸催化剂，其中可以使用布朗斯台德酸或路易斯酸催化剂有效地进行反应。 例如，醇的苯甲酰化反应也可以容易地进行，此外，可以容易地回收和回收催化剂。 由通式[1]表示的芳基双（全氟烷基磺酰基）甲烷的对位（其中R 1表示取代或未取代的芳基，Rf 1和Rf 2彼此独立，表示全氟烷基 ），五氟苯基双（全氟烷基磺酰基）甲烷例如负载在聚苯乙烯树脂上，由通式[3]表示的聚苯乙烯担载的芳基双（全氟烷基磺酰基）甲烷（其中R 3表示取代或未取代的亚芳基 ，Rf 1和Rf 2与上述相同）。
