YieldReaction ConditionsOperation in experiment
With triethylamine at 20 - 60℃; for 2h; 2 17.6 g (0.043 mol) of ethyl 4,4,4-trifluoro-3-trifluoroacetyl-butanoate with a purity of 85.6 % were mixed with 4.10 g (0.041 mol) of triethylamine in a glass flask equipped with a condenser cooled down to 50C. The reaction was started at room temperature, but due to the exothermic nature of the reaction, the temperature increased to 6O0C. After 2 h, the reaction medium was washed first with a NH4Cl saturated water solution (2 x 40 ml) and then with 40 ml of water. The organic phase was separated from the aqueous phase by decantation and dried over MgSO4. Analysis by gas chromatography showed a complete conversion of ethyl 4,4,4-trifluoro-3-trifluoroacetyl-butanoate, with a selectivity of 99 % into ethyl 4,4,4-trifluoro-3-trifluoromethyl crotonate (ETFMC). ETFMC was then distilled under vacuum.

With SF4 In cyclohexane; water II 1,1,1,4,4,4-Hexafluoro-2-(trifluoromethyl)butane EXAMPLE II 1,1,1,4,4,4-Hexafluoro-2-(trifluoromethyl)butane A 300 mL autoclave was charged with 21.0 g (0.1 mol) 4,4,4-trifluoro-3-(trifluoromethyl)butyric acid (prepared by hydrogenation and hydrolysis of commercially available ethyl 4,4,4-trifluoro-3-(trifluoromethyl)crotonate), 25 mL cyclohexane, and 38 g (0.35 mol) SF4. The contents were heated to 65°-70° C. for 3 days, vented through a KOH scrubber, and poured into a separatory funnel containing 40 mL water. The aqueous layer was extracted with 2*25 mL portions of cyclohexane, and the combined organic layers distilled. An azeotrope of the desired product and cyclohexane was obtained (bp 41°-2° C.), which contained about 20% cyclohexane. The desired HFC was obtained in 23% yield following extraction with light mineral oil and distillation. A second distillation provided material of 99% purity, bp 43°-44° C. 1H NMR (CDC13): δ 3.25 (m, 1 H) and 2.63 (dq, 2 H); 19 F NMR: 67.3 (3 F) and 69.5 (5F) ppm. %F=70.
