- One-pot reaction for the synthesis of fluorinated β-diketones
-
Fluorinated β-diketones have been synthesized in high yield from the one-pot reaction of silyl enol ethers with perfluoroalkyl iodides initiates with Na2S2O4/NaHCO3, followed by treatment with diethylamine and acid hydrolysis.

- ELECTROCHEMICAL SYNTHESIS OF PERFLUOROALKYLACETONES
-
The interaction of electrochemically generated radicals in the electrolysis of the perfluorocarboxylic acids RFCF2COOH (I), where RF = F (a), CF3 (b), C2F5 (c), C3F7 (d), C5F11 (e). and C7F15 (f), with isoprenyl acetate (II) was studied.The dependence of the results of the electrolysis on the adsorption capacity of the anode permits the proposition that the interaction of (II) with the ECG-radicals occurs close to the surface of the electrode.The yield of the perfluoroalkylacetones comprised 30-37percent.

- Annelation d'enamines par les cetones α,β-ethyleniques fluorees. VI (1): Reaction d'aromatisation
-
Various perfluoroalkylacetones were prepared by addition of perfluoroalkyliodides to 2-methoxypropene and condensed with 1-pyrrolidinocyclopentene or -cyclohexene.An annelation-aromatisation process led to 4-perfluoroalkyl-6-pyrrolidinoindanes and 1-perfluoroalkyl-3-pyrrolidino-5,6,7,8-tetrahydronaphthalenes.

- A Carbon-13 Nuclear Magnetic Resonance Study of Compounds Substituted by a Perfluoroalkyl Chain
-
The 13C NMR spectra of alkanes, alkanones and cyclohexanones substituted by perfluoroalkyl groups, RF, have been studied.The influence of the perfluoroalkyl group on the chemical shifts of other carbons of the molecules is the same regardless of the RF chain length.
