Li, AnRong published the artcileA convenient trifluoroacetylation of amines with trifluoroacetic acid and titanium tetrachloride, Recommanded Product: N,N-Diethyl-2,2,2-trifluoroacetamide, the publication is Chinese Journal of Chemistry (1993), 11(2), 190-2, database is CAplus.
Treating R1R2NH (R1 = H, R2 = Ph, cyclohexyl, allyl, Me2CHCH2, 2-NH2C6H4, 2-HOC6H4; R1 = R2 = Et; R1 = Ph, R2 = Me) with CF3CO2H, 2 equiv Et3N, and 2 equiv TiCl4 in Et2O, MeCN, or CH2Cl2 gave 40-75% R1R2NCOCF3 (same R1, R2); in the case of o-phenylenediamine, the product is 2-(trifluoroacetyl)benzimidazole.
