Method of preparing perfluoro-3-methyl-2-butanone

The invention discloses a method of preparing perfluoro-3-methyl-2-butanone through a reaction of hexafluoropropylene and trifluoroacetyl fluoride under effect of a liquid-phase catalyst which includes a main catalyst, a cocatalyst, an additive and an organic solvent, wherein the main catalyst is selected from metal fluorides and/or metal bifluorides; the cocatalyst is selected from C6-C9 perfluoroolefines; the additive is selected from crown ether and/or crown ether-like compound; the organic solvent is selected from polar aprotic solvents. The preparation method can achieve one-step reaction, is high in reaction speed, and is high in product yield.

Catalytic synthesis of certain perfluorinated ketones and study of their structure by 19F NMR spectroscopy

An efficient catalyst of a perfluorinated ketone synthesis of a high selectivity in the absence of solvent was proposed. Products of reaction of perfluorinated fluorides of various structures with tetrafluoroethylene and hexafluoropropylene in the presence of efficient catalysts without solvent were examined. The structure of the resulting products and their isomeric composition were identified by 19F NMR spectrscopy. Pleiades Publishing, Ltd., 2013.

PREPARATION OF COMPOUNDS HAVING A PERFLUOROALKYLCARBONYL GROUP

Carbonyl fluoride and carboxylic acid fluorides can be added onto perfluoroalkenes, for example hexafiuoropropene, under unpressurized conditions. Perfiuoroalkylcarboxylic acid fluorides or ketones having a perfluoroalkyl group can thus be prepared in a simple way.
