An entirely new methodology for synthesizing perfluorinated compounds: synthesis of perfluoroalkanesulfonyl fluorides from non-fluorinated compounds

Elemental fluorine in organic chemistry (1997–2006)

“…The use of partially fluorinated substrates for perfluorination has been used to great effect recently by Okazoe et al at the Asahi Glass company [25][26][27][28]. Suitable partially fluorinated esters are synthesised by condensation of a perfluoroacid fluoride with an alcohol derivative (Scheme 4).…”

“…In addition, perfluoroalkane sulfonyl fluorides could also be synthesised by this general strategy (Scheme 6) [25].…”

Synthesis and polymerization of a novel perfluorinated monomer

“…After distillation, the obtained ester was fluorinated with elemental fluorine diluted with nitrogen in the same manner as described in the literature [7][8][9][10]. In the case of using 20 vol% fluorine/nitrogen gas, the yield of the perfluorinated ester 3 determined by 19 F NMR was 86%.…”

“…Recently, our group has developed new and innovative methodology for the synthesis of various perfluorinated compounds via a direct fluorination reaction (Scheme 1) [7][8][9][10][11]. From the perspective of applicability for synthesizing desired perfluorinated compounds, the methodology would be superior to other perfluorination reactions.…”

Synthesis of perfluorinated carboxylic acid membrane monomers by utilizing liquid-phase direct fluorination

“…We have also reported the synthesis of perfluoroalkanesulfonyl fluorides [11], and perfluoroketones [12].…”
