Di-tert-Bu peroxide initiated free radical addition of THF to various fluorinated alkenes (CF2:CH2, CF2:CFH, CH2:CHCF3, CF2:CFCF3, CF2:CFC5F11, CF2:CFOCF2CF(CF3)OCF2CF2SO2F) gives either bidirectional addition products 2-R-THF (R = CF2CH3 (1), CH2CHF2 (2), CF2CH2F (3), and CFHCHF2 (4)) or unidirectional products (R = CH2CH2CF3 (5), CF2CHFCF3 (6), CF2CHFC5F11 (7), and CF2CHFOCF2CF(CF3)OCF2CF2SO2F (8)) depending on the structure of the alkene. Reaction of dioxane with CF2:CFOCF2CF(CF3)OCF2CF2SO2F gives a single product 2-R-dioxane, R = CF2CHFOCF2CF(CF3)OCF2CF2SO2F (9). In the case of hexafluoropropene or perfluoroallylbenzene, reaction with an excess of THF gives only the monosubstituted products 2-R-THF (R = CF2CHFCF3 (6) and CF2CFHCF2C6F5 (11)) resp. When THF is reacted with a 3:1 M excess of the same two perfluoroalkenes, the disubstituted products 2,5-R2-THF (R = CF2CHFCF3 (10) and CF2CFHCF2C6F5 (12)) are formed resp. When 18-crown-6 is reacted in the same way with fluoroalkenes in a 1:1 molar ratio, the monosubstituted products 18-crown-6-CH2CH2CF3 (13), 18-crown-6-CF2CHFCF3 (14), 18-crown-6-CF2CFHCF2C6F5 (15), and 18-crown-6-CF2CHFOCF2CF(CF3)OCF2CF2SO2F (16) were obtained. Polyfluorinated 18-crown-6 products containing three and two polyfluroalkyl/aryl groups were prepared when 18-crown-6 is reacted with a 3:1 M excess of perfluoropropene and perfluoroallylbenzene to give 18-crown-6-(CF2CHFCF3)3 (17) and 18-crown-6-(CF2CFHCF2C6F5)2 (18), resp. (Pentafluorophenoxy)trimethylsilane reacts with 11 in the presence of a catalytic amount of CsF to give compound 2-R-THF, R = CF2CFHCF2C6F4OC6F5 (19). Two mols. of 11 are bridged by reaction with Me3SiOCH2CF2CF2CH2OSiMe3 to give THF-CF2CFHCF2C6F4OCH2CF2CF2CH2OC6F4CF2CHFCF2-THF (20), while 12 forms the macroheterocycle 2,5-R’-THF, R’ = -CF2CFHCF2C6F4OCH2CF2CF2CH2OC6F4CF2CFHCF2– (21) under similar reaction conditions. The La triflate complexes of 18-crown-6 (22) and 18-crown-6(CF2CFHCF3) (23) were prepared and the structures were obtained via single-crystal x-ray anal. Although crystals suitable for single-crystal x-ray anal. could not be formed, La triflate complexes were formed with polyfluorinated ethers 15 and 16 to give the fluorinated complexes La(OSO2CF3)3(18-crown-6-CF2CFHCF2C6F5)(H2O) (24) and [La(18-crown-6-CF2CFHOCF2C(CF3)FOCF2CF2SO2F)]3+[CF3SO3–]3 (25) resp. The acid salt La[N(SO2CF3)2]3 (26) was also prepared and characterized, and reacted with dibenzo-18-crown-6 to give the complex dibenzo-18-crown-6-La[N(SO2CF3)2]3 (27).
