실험 절차
N,N,N′,N′-Tetraethylformamidinium methylsulfate (4 g) is added to water (25 ml) and the resulting mixture is cooled to 0° C. This mixture is then added to a cooled solution of ammonium hexafluorophosphate (4.9 g) in water (25 ml). The formed precipitate is collected by filtration. The precipitate is then washed with cold water (2×10 ml) and then with diethyl ether (10 ml). Drying in vacuo gives N,N,N′,N′-tetraethylformamidinium hexafluorophosphate (18, R6=Et, R7=Et) as a yellow solid. 1H NMR (DMSO-d6), 7.92 (1H), 3.85-3.54 (8H), 1.45-1.38 (12H).
