Abstract
Processes for producing a N,N-dialkyl perfluoroalkyl-sulfonamide product of the formula R—S(O)—NRR(I) in which Rrepresents fully or partially fluorinated alkyl groups with carbon 1 to 12 and Rand Rrepresents linear or branched or cyclic alkyl, alkene or alkyne groups with carbon 1 to 12, wherein R=Ror R≠R. In some embodiments, a reaction proceeds by contacting a perfluoroalkylsulfonyl halide of the formula: X—S(O)—R, (II), in which X represents F, Cl, Br or I, with dialkylamine of the formula HNRR, under conditions sufficient to produce the desired N,N-dialkyl perfluoroalkylsulfonamide product of Formula I. In some embodiments, the reaction is carried out using a solvent of Formula I.
