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.
A ketone with perfluoroalkyl chains has been developed for the extraction of M(II) (M = Sn, Cd, Hg, Pb) and As(V) from aqueous and organic solvents under heterogeneous and homogeneous conditions using the unique thermomorphic properties of these ligands.Figure optionsDownload as PowerPoint slide
