A new version of Umemoto's reagents: A three-step one-pot preparation of 2,3,7,8-tetrafluoro-S-(trifluoromethyl)dibenzothiophenium triflate

A new one-pot method was developed for the practical preparation of powerful electrophilic trifluoromethylating agent, 2,3,7,8-tetrafluoro-S-(trifluoromethyl)dibenzothiophenium triflate 2. This method comprised of three steps; (1) in situ generation of trifluoromethanesulfinyl trifluoroacetate 7, (2) treatment of 3,3′,4,4′-tetrafluorobiphenyl with 7 in the presence of trifluoromethanesulfonic acid and trifluoroacetic anhydride, and (3) treatment of the resulting mixture with hydrogen peroxide. By means of this effective three-step one-pot method, 2 was prepared in a good isolated yield by simple water-washing method. It is thus expected that easy access to 2 may lead to its wider or new applications to many areas, because tetrafluoro reagent 2 is much more powerful than 2,8-difluoro-S-(trifluoromethyl)dibenzothiophenium triflate 1.

A novel method for preparing S-(perfluoroalkyl)-dibenzothiophenium trifluoromethanesulfonate

A method for preparing S-(perfluoroalkyl)-dibenzothiophenium trifluoromethanesulfonate shown as a general formula (I) by a one-pot process with significant effects is disclosed by the invention. The method includes reacting a biphenyl compound, perfluoroalkyl sulfonate, trifluoroacetic anhydride and trifluoromethanesulfonic acid. The biphenyl compound can be recovered and utilized so that the method is an environmentally friendly preparing method.

Industrial production method of 3,3'-difluorobiphenyl

The invention relates to a novel, safe, economical and environment-friendly production method of a useful chemical 3,3'-difluorobiphenyl. High-purity 3,3'-difluorobiphenyl can be prepared and obtained in a high-yield manner by making 3-fluorophenyl halogenated magnesium react with 1,2-dihalogenethane under the catalytic action of a trivalent ferric salt, and then treating a product by using an alkali or an acid. In addition, the method comprises a step of using and recycling an ethylene gas released in the reaction to prepare the initial raw material 1,2-dihalogenethane of the reaction, wherein the ethylene gas is a potential air pollutant.
