摘要:A process for the synthesis of the fluorochemical compound having formula n n R.sub.f SO.sub.2 N(CHR.sup.2 --CHR.sup.2 COO.sup.-) R.sup.1 N.sup.+ n n (R) 2 H n wherein R f is a fluoraliphatic radical containing at least 3 carbon atoms. The synthesis involves reaction of compounds of formula R f SO 2 N(H)R 1 N(R) 2 and CHR 2 â•?CH 2 COOH in solution at elevated temperatures. The process can be used to synthesize the fluoroaliphatic amphoteric amino carboxylate surfactant having the formula: n n C.sub.6 F.sub.13 SO.sub.2 N(C.sub.2 H.sub.4 COO.sup.-) C.sub.3 H.sub.6 n n N + (CH 3 ) 2 H n which compound is useful in aqueous film-forming foamable concentrates for extinguishing flammable liquid fires.

摘要:The present invention provides an improved process for preparing an oxazoline compound of the formula: (I) wherein R 1 and R 2 are independently hydrogen, sulfide, sulfoxide, sulfonyl, optionally substituted lower alkyl, optionally substituted aralkyl, optionally substituted aryl or optionally substituted polycyclic arylyl; or R 1 and R 2 combined together with the carbon atoms to which they are attached form an optionally substituted fused 6-member aromatic ring provided that R 1 and R 2 are attached to carbon atoms adjacent to each other; and R 3 is hydrogen, sulfide, sulfoxide, sulfonyl, optionally substituted lower alkyl, optionally substituted aralkyl, optionally substituted aryl or optionally substituted polycyclic arylyl; or an enantiomer therof; or an enantiomeric mixture therof; comprising the step of contacting an acylamino alcohol compound to a suitable amount of fluoroalkanesulfonyl fluoride compound and organic basic reagent. By using a fluoroalkanesulfonyl fluoride compound with an organic basic reagent, the present invention efficiently converts acylamino alcohol compounds into highly chemoselective oxazoline compounds with a remarkable variety of substrates, mild conditions and relatively short reaction time.
