Two new perfluoroalkylvinyl ethers 7,7-dichloro-3-oxaperfluoro-1-heptene and 10,10-dichloro-3,6-dioxaperfluoro-5-methyl-1-decene were synthesized. The starting material 4,4-dichloroperfluoro-1-butene was oxidized with NaOCl or H2O2 to give the corresponding epoxide, with was rearranged with catalytic amount of Et3N to 4,4-dichlorobutyryl fluoride (I). I reacted under catalyzation of F- with perfluoropropylene oxide to form FC(O)CF(CF3)[OCF2CF(CF3)]n-1O(CF2)3CFCl2 (n = 1, 2) (II). II was decarboxylated at 200-230 癈 in the presence of Na2CO3 to give the title compounds
