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.

Reductive alkylation of perfluorocarboxylic acid esters with CCl 3F or CCl4 and synthesis of higher linear perfluoroketones

Barbier-type reductive alkylation of perfluorocarboxylic acid esters (I) with CFCl3 and activated Al was successfully performed to give α,α-dichloroperfluoroketones (II). A similar reaction of CF 3COOEt with CCl4 and Al provided a convenient synthesis of CF3COCCl3. Ketones (II) were fluorinated further with SbF5 to form higher linear perfluoroketones (IX). An alternative approach to the synthesis of ketones (IX) was proposed by reductive perfluoroalkylation of esters (I) under the action of RFI and Al.
