发明名称 ARYLBIS (PERFLUOROALKYLSULFONYL) METHANE, METAL SALT OF THE SAME, AND PROCESSES FOR PRODUCING THESE
摘要 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, ä4-(pentafluorophenyl)-2,3,5,6-tetrafluorophenylübis(triflyl)methane and the like are obtained at a high yield.
