Title compds. [I; n = 1-3; X = F, Cl, Br; a = 0-2; b = 0-2; Y = acid deriv.; Rf, R'f = F, perfluoroalkyl were prepd. by decarboxylating II [X' = Cl, Br; Z = F, Cl, Br, OH, NRR', OA; R,R' = alkyl or aryl; A = alkali metal . Thus, 35.67 g of a compsn. contg. FSO2C2CF2OCF(CF2Cl)COF 12.8, FSO2CF2CF2OCF(CF2Cl)CF2OCF (CF2Cl)COF (57.4%), and FSO2CF2CF2O[CFCCF2Cl)CF2O!2CF(CF2Cl)COF (6.82%) was added to amixt. of 50 ml tetraglyme and 8.0 g Na2CO3 and heated to give 25.99 g of a product contg. FSO2CF2CF2OCF: CF2(III) (17.4%), FSO2CF2CF2O[CF2(CF2Cl)CF2O!2CF: CF2[1VK2S2O8, NaHSO3, and C7F15CO2K to give a polymer.
