Participants

Reaction Steps

Trimethylamine (12.4 g, 0.21 mol) was distilled into a stirred solution of 47.8 g (0.20 mol) of methyl 3-methylsulfonyltetrafluoropropionate in 100 ml of ether. The mixture was stirred overnight, filtered under nitrogen, and the solid dried under vacuum. There was thus obtained 52.1 g (88%) of tetramethylammonium 3-methylsulfonyltetrafluoropropionate, mp 98° to 100°, as deliquescent crystals. NMR (DMSO-d6): 1H 3.40 (t, JHF 2 Hz, 3H, CH3SO2) and 3.17 ppm (s, 12H, (CH3)4N+); 19F-112.3 (t, JFF 3.0 Hz, 2F, CF2C=O) and -114.4 ppm (T, JFF 3.0 Hz, of m, 2F, CF2SO2). Anal. Calcd. for C8H15F4NO4S: C, 32.32; H, 5.09; N, 4.7. Found: C, 32.20; H, 5.17; N, 4.44.
