Trifluoroacetylation of amines with N-trifluoroacetyl-nylon 66: Trifluoroacetylation of amines with N-trifluoroacetyl-nylon 66. Schuttenberg, H.; Schulz, Rolf C. (La Plata, Argent.). Angew. Chem., 88(24), 848-9 (German) 1976. CODEN: ANCEAD. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 23, 25, 27 Adding 10 ml (CF3CO)2O to a suspension of 3.7 g powd. nylon 66 [32131-17-2] in 50 ml CHCl3 vigorously stirred at 0.degree. and warming slowly to room temp. gives after 6 hr 6.5 g [-N(COCF3)CO(CH2)4CON(COCF3)(CH2)6-] (I) [61155-86-0], which forms CF3CO2H quant. when treated with H2O without degrdn. of the polymer chain.In this experiment, several chemicals are used like 110-89-4 and 39995-51-2 Stirring 230 mg I with 1 mmole amine in 5 ml MeCN 12 hr at room temp. gives PhCH2NHCOCF3 [7387-69-1], L-PhCH(Me)NHCOCF3 [39995-51-2], PhNHCOCF3 [404-24-0], C6H13NHCOCF3 [687-09-2], CF3CONH(CH2)6NHCOCF3 [14815-14-6], 1-(trifluoroacetyl)piperidine [340-07-8], and p-O2NC6H4NHCOCF3 [404-27-3] in yields of 91, 93, 89, 95, 96, 95, and 40%, resp. .

Gas-chromatographic separation of aromatic amides of polyfluorocarboxylic acids: Gas-chromatographic separation of aromatic amides of polyfluorocarboxylic acids. Kulikova, G. 404-24-0 is also in the experiment. S.; Kirichenko, V. E.; Pashkevich, K. I.; Postovskii, I. Ya.; Glebova, S. A. (Inst. Chem., Sverdlovsk, USSR). Zh. Anal. Khim., 32(12), 2417-20 (Russian) 1977. CODEN: ZAKHA8. ISSN: 0044-4502. DOCUMENT TYPE: Journal CA Section: 80 (Organic Analytical Chemistry) The gas chromatog. of substituted anilides of trifluoroacetic, 2,2,3,3-tetrafluoropropionic (I), 3-(trifluoromethoxy)-2,2,3,3-tetrafluoropropionic (II), and pentafluorobenzoic acids was studied on various stationary phases. The best sepns. were obtained for the I and II anilides at 140-160° on a column packed with 5% XE 60 on Chromaton NAW. An electron-capture detector was used. .
