Staab, Heinz A.'s team published research in Chemische Berichte in 95

Staab, Heinz A. published the artcileN-Trifluoroacetyl- and N-trichloroacetylimidazole, Name: N,N-Diethyl-2,2,2-trifluoroacetamide, the publication is Chemische Berichte (1962), 2070-2, database is CAplus.

The syntheses and reactions of N-trifluoroacetylimidazole (I) and N-trichloroacetylimidazole (II) are described. N,N’-Carbonyldiimidazole (III) (20.5 g.) in 100 cc. dry THF treated dropwise with 28.8 g. CF₃CO₂H in 80 cc. THF, cooled several hrs., and filtered gave imidazolium trifluoroacetate (IV), m. 136-7° (tetrahydrofuran); distillation of the filtrate yielded 14.4 g. I, b₁₄ 45-6°. Imidazole (V) (25.8 g.) in 120 cc. dry THF treated dropwise with cooling with 39.9 g. (CF₃CO)₂O in 50 cc. THF, filtered from the IV, and distilled gave 24.8 g. I. CCl₃CO₂H (39.1 g.) and 19.5 g. III in C₆H₆ gave in the usual manner imidazolium trichloroacetate (VI), m. 93-4.5° (decomposition) (CHCl₃), and from the filtrate 18.5 g. II, b_0.001 60-2°, m. 38.5-40°. (CCl₃CO)₂O (31.3 g.) added dropwise with cooling to 17.8 g. V in 170 cc. C₆H₆, filtered from the VI, and distilled yielded 21.7 g. II. I treated in Et₂O or THF at room temperature with an equivalent amount of an appropriate alc. gave the following CF₃CO₂R (R, % yield, m.p. or b.p./mm., and n²⁰_D given): cyclohexyl, 73, 148-9°/760, 1.3839; iso-Am, 74, 119-20°/760, 1.3513; Me₃C, 73, 83°/760, 1.3302 (at 25°); Ph, 75, 48-9°/16, 1.4187 (at 25°). II gave similarly the following CCl₃CO₂R (same data given): cyclohexyl, 81, 122.5-3.5°/14, 1.4805; iso-Am, 84, 97.5-98°/15, 1.4520; Me₃C, 78, 25-6°, -; Ph, 79, 124.5-25°/14, 1.5253. I treated at room temperature with an equivalent amount of an appropriate amine in THF or Et₂O and evaporated, and the residue washed with H₂O gave the corresponding amides of CF₃CO₂H (% yield, and m.p. or b.p./mm. given): diethylamide, 74, 157-8°/760; anilide, 83, 89-90°; 2-naphthylamide, 83, 146-7.5°; p-nitranilide, 84, 151-3°; carbethoxymethylamide, 51, 51°. II gave similarly the following amides of CCl₃CO₂H (same data given): diethylamide, 82, 26-7°; anilide, 90, 94.5-5.5°; N-methylanilide, 87, 72-2.5°. p-H₂NC₆H₄CO₂H (4.12 g.) and 10 g. I in Et₂O at room temperature gave 5.5 g. p-CF₃CONHC₆H₄CO₂H (VII), m. 284-5° with resolidification to a solid which does not melt up to 350°. A similar run with equivalent amounts of reactants gave only 38% VII. VII heated 1 h. at 300° gave with the elimination of CF₃CO₂H a polyamide of p-H₂NC₆H₄CO₂H.
