Splitting patterns use s, d, t, q, m, and br to denote singlet, doublet, triplet, quartet, multiplet, and broad, respectively. 13 The C NMR spectrum was measured with a Varian Gemini-300 (125MHz) nuclear magnetic resonance device, used as an internal standard (77.0ppm of CDCl 3 ) expressed in ppm of solvent used. 19 The FNMR spectrum was measured with a Varian Gemini-300 (282MHz) nuclear magnetic resonance device, used as an internal standard (-64.0ppm CF 3 C 6 h 5 ) expressed in ppm of solvent used. High performance liquid chromatography (HPLC) analysis was performed using a Shimadzu LC-10AD instrument and SPD-M10A UV detector with a chiral column (Daicel AS or OD-H).

Abstract

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.
