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

A new synthetic procedure for the preparation of perfluoroalkanesulfonyl fluorides utilizing liquid-phase direct fluorination with elemental fluorine has been developed. Direct fluorination of a partially fluorinated ester, which has alkanesulfonyl fluoride in the end, was synthesized from non-fluorinated counterparts and perfluorinated acid fluoride according to the PERFECT process, gave the desired perfluorinated product in moderate yield as well as by-products arising from CS bond cleavage. The results of the direct fluorination of some model substrates suggest that the CS bond cleavage occurred due to radical formation at the α-position rather than the β-position.

Various synthetic approaches to fluoroalkyl p-nitrophenyl ethers

Homologous 1H,1H-perfluoroalkyl p-nitrophenyl ethers (alkyl = C2-C8) were synthesized using different methods. The results are discussed in context with contradictory comments of the literature. The fluoroalkoxylation of p-chloronitrobenzene occurs in only one step, but it is limited to small fluoroalkyl groups. The fluoroalkylation of p-nitrophenol via sulphonic acid esters is a better synthetic route. Differences in reactivity and yield between tosylates, mesylates and inflates are found and discussed. The preferred synthesis includes the use of trifluoromethane sulphonic acid esters.
