Participants

Reaction Steps

Methyl trifluoromethanesulfonate, 4.92 g (0.03 mol), was added dropwise to 0.03 mol of tris(dimethylamino)sulfonium 1,1,2,3,3,3-hexafluoro-2-(heptafluoropropoxy)propoxide (prepared as in Example 13) in 30 mL of benzonitrile. The reaction mixture was stirred for 1.5 h and then the more volatile portion of the reaction mixture was distilled out at reduced pressure and redistilled at atmospheric pressure to give 6.39 g (58%) of methyl 1,1,2,3,3,3-hexafluoro-2-(heptafluoropropoxy)propyl ether as a colorless liquid: bp 94°-96°; 1H NMR (CDCl3) δ3.70 ppm (s); 19F NMR (CD3Cl) δ-81.0 ppm (m, 3F), -82.1 ppm (m, 3F), -82.4 ppm (m, 2F), -88.7 ppm (m, 2F), -130.3 ppm (m, 2F) and -144.8 ppm (m, 1F). Anal. Calcd. for C7H3F13O2 : C, 22.96; H, 0.82. Found: C, 22.95; H, 0.78.
