The present invention provides a method for producing various types of arylbis(perfluoroalkylsulfonyl)methane having a bulky aryl group and an electron-accepting aryl group in which synthesis was conventionally considered to be difficult, at high efficiency; a novel arylbis(perfluoroalkylsulfonyl)methane that can be widely applied to asymmertric catalyst, various types of functional materials and the like; and a metallic salt thereof. In addition, excellent catalysts are also provided. An aryl halomethane is reacted with a sodium trifluoromethane sulfinate, the arylmethyl triflone produced thereby is reacted with a t-BuLi and the like, the lithium salt of the arylmethyl triflone obtained is reacted with a trifluoromethane sulfonic acid anhydride, and an arylbis(trifluoromethylsulfony)methane such as pentafluorophenylbis(triflyl)methane, 4-(pentafluorophenyl)-2,3,5,6-tetrafluorophenyl}bis(triflyl)methane and the like are obtained at a high yield.
本发明提供了一种高效生产各种类型芳基双(全氟烷基磺酰基)甲烷的方法,这些甲烷具有传统上被认为难以合成的大块芳基和电子接受芳基;提供了一种新型芳基双(全氟烷基磺酰基)甲烷,可广泛应用于异氰酸酯催化剂、各种功能材料等;还提供了其金属盐。此外,还提供了优良的催化剂。芳基卤代甲烷与三氟甲烷亚磺酸钠反应,由此生成的芳基甲基三氟丙烯与 t-BuLi 等反应,得到的芳基甲基三氟丙烯的锂盐与三氟甲烷磺酸酐反应、高产率地获得芳基双(三氟甲基磺酰基)甲烷,如五氟苯基双(三氟甲基)甲烷、4-(五氟苯基)-2,3,5,6-四氟苯基}双(三氟甲基)甲烷等。
