Versuchsvorschrift
Ethyl formimidate hydrochloride (0.555 g, 5 mmole), 2,2,2-trifluoroethylamine hydrochloride (0.677 g, 5 mmole) and potassium carbonate (0.345 g, 2.5 mmole) are suspended in 20 ml CH2Cl2 and treated with 1 ml H2O. The mixture is shaken vigorously for 3 minutes. The organic phase is separated and the aqueous extracted twice with 10 ml portions of CH2Cl2. The combined organic phase is dried and the CH2Cl2 distilled through a Vigreauxe column to give the Ethyl N-(2,2,2-trifluoroethyl)formimidate. n.m.r. δ1.333 t (CH3CH2); 3.8 q (j=10 c.p.s., CF3CH2) 4.23 q (j=7.5, CH3CH2O); 7.6 S (H--C=N).
