    • 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 asymmetric 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 sulfinic 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.

    • The present invention provides a method for preparing ester or thioester that can conduct catalytic esterification reaction with an equimolar amount of carboxylic acid and alcohol, or catalytic thioesterification reaction with carboxylic acid and an equimolar amount or small amount of thiol, and can be expected as an industrial method that needs an enormous amount of synthesis in the light of green chemistry. By using hafnium chloride (IV), especially tetravalent hafnium compounds represented by hafnium chloride (IV)·(THF)2 or hafnium (IV)t-butoxide as a (poly) condensation catalyst, direct condensation reaction is conducted from carboxylic acid and an equimolar amount of alcohol or a little smaller amount of thiol, in the nonpolar solvent such as toluene and the like, in a deoxidization atmosphere and under heating reflux, and the reaction synthesizes ester monomer or thioester monomer, polyester or polythioester. When heating reflux is conducted by using a nonpolar solvent, it is preferable to remove azeotropic water from the reaction system.
