The preparation of a ketone with two long chain perfluoroalkyl groups is reported via the coupling reaction of a perfluorinated alkylzinc reagent and a perfluoro-acid chloride. This ketone has been investigated in the heterogeneous removal of heavy metals M2+ (M = Sn, Cd, Pb, Hg) and As5+ from aqueous solutions and removal of these metals from organic solvents using the unique thermomorphic properties of the fluorous ketone. In addition, a comprehensive 13C NMR study of one of the intermediates in the synthesis, 2H,2H,3H,3H-perfluoronanoic acid, has allowed the determination of all 1JC-F and 2JC-F coupling constants. Also reported is the crystal structure of the acid CF3(CF2)5CH2CH2CO2H.

New semi-fluorinated amidosulfobetaines, homologs of hydrocarbon amidosulfobetaines (ASB) commonly used in two-dimensional gel electrophoresis (2DE), were prepared in three steps from 2-F-alkylethyl iodide or F-alkyl iodide. Their synthesis was described and their air-water interface properties were investigated and compared with their perhydrogenated counterpart properties. The influence of the relative lengths of the perfluorinated and hydocarbonated moieties was discussed. 2DE of a rat testicular membrane fraction was performed comparatively using one of these fluorinated sulfobetaines and its hydrocarbon homolog; these preliminary results showed the great potential of the semi-fluorinated sulfobetaines in proteomic analysis.
Selective mono- and di{(perfluoroalkyl)acylation} of ferrocene

The selective synthesis of mono- and 1,1′-di{(perfluoroalkyl)acylated} ferrocenes by Friedel-Crafts acylation with (perfluoroalkyl)acyl halides is described. The acyl derivatives were further converted to the corresponding (perfluoroalkyl)alkyl ferrocenes by reduction of the carbonyl group with LiAlH4/AlCl3. Electrochemical studies of all the obtained substituted ferrocenes were carried out to assess the influence of the perfluoroalkyl ponytails on their redox behavior.
