Abstract
Abstract There was lack of fluorination reagents around 1978 when the author started his fluorine research. This account presents the author's ideas and development of many reagents which include (perfluoroalkyl)phenyliodonium triflates (FITS reagent) and sulfates (FIS), (1,1-dihydroperfluoroalkyl)phenyliodonium triflates (FMITS), N -trifluoromethyl- N -nitroso-benzene- and -trifluoromethane-sulfonamide (TNS-B and -Tf), N -fluoropyridinium salt series (F-Plus™), N -fluoropyridinium-2-sulfonate series, N , N ′-difluoro-2,2′-bipyridinium salt series (MEC-31, SynFluor™), N , N ′-difluoro-1,4-diazoniabicyclo[2.2.2]octane salts, S -, Se -, and Te -(trifluoromethyl)dibenzo-thio-, -seleno-, and -tellurophenium salts and their 3-sulfonate series, O -(trifluoromethyl)dibenzofuranium salts and their precursors, 4- tert -butyl-2,6-dimethylphenylsulfur trifluoride (FLUOLEAD™), and arylsulfur chlorotetrafluorides. These reagents have made new areas and significant advancement in fluorine chemistry. The incidental fruits are also described, which include discoveries of new cyclic carbene reactions of N -fluoropyridinium salts and the first practical industrial method for production of arylsulfur pentafluorides. Application of N -fluoropyridinium salts to electronic materials is briefly mentioned.
