Reaction Conditions:

with iron(III) trifluoride;18-crown-6 ether in acetonitrile at 90; for 10 h;Autoclave;Large scale;

Steps:

6 Example 6
In a 1 liter, 316 autoclave, first add 0.5 mol of ferric fluoride, 0.1 mol of 18-crown ether-6, and then pumpVacuum, pass anhydrous acetonitrile, then stir,Quickly pass 1 mol of hexafluoropropylene and 1 mol of heptafluoroisobutyryl fluoride,After the completion of the materials,The temperature was maintained at 90 ° C, the reaction time was 10 hours, and after the reaction was completed, it was cooled to 15 ° C, and allowed to stand for separation. The upper layer was an acetonitrile solvent in which a metal fluoride and a co-solvent were dissolved, and the lower layer was a colorless bis (perfluoroisopropyl group). The ketone was 3354.6 g, the purity was 99.2% (GC analysis), and the yield of bis(perfluoroisopropyl)one was 96.1%.
