- Ozonolysis of alkenes and studies of reactions of polyfunctional compounds: LXV.* Ozonolysis of perfluoro-1-octene in Freon-113
-
Ozonization of perfluoro-1-octene in Freon-113 yields the corresponding ozonide whose catalytic hydrogenation over Pd/C or hydride reduction leads to formation of perfluoroheptanoic acid; the reduction with lithium aluminum hydride gives 2,2,3,3,4,4,5,5,6,6,7,7,7-tridecafluoro-1-heptanol. Ozonization of perfluoro-1-octene in Freon-113 containing excess (≥3 equiv) alcohol affords the corresponding perfluoroheptanoic acid ester.

- Reactivity of perfluorohexyl iodide with N,N-disubstituted amides and esters in the presence of a metal couple and radical initiator
-
The reactivity of perfluorohexyl iodide with N,N-disubstituted amides or ethyl formate as solvents and reactants, in the presence of a zinc-copper metal couple and radical initiator, has been investigated.In each case, the corresponding perfluorinated carbonyl compounds, such as aldehydes, amides, ketones and esters, were obtained in good yield, thus proving the efficacy of this reaction.The influence of the radical initiator on the reaction mechanisms has been studied and is discussed. - Keywords: Reactivity; Perfluorohexyl iodide; Disubstituted amines; Zinc-copper metal couple; Radical initiator; NMR spectroscopy; IR spectroscopy; Mass spectrometry

- Process for functionalizing perfluorohalogenoalkanes
-
The present invention relates to the process of preparing perfluoro functional compounds from a perfluorohalogenoalkane having the general formula: wherein RF is a saturated, unsaturated, straight, or branched chain perfluoroalkyl radical containing 2 to 12 carbon atoms, and X is selected from chlorine, bromine, or iodine, comprising reacting said perfluorohalogenoalkane with a functionalizing reagent in the presence of a metallic couple dispersed in a sulfoxide-type solvent, said metallic couple having the general formula: wherein M1 is metal selected from Group IB, IIA, IIB, or IIIA of the Periodic Table and M2 is a metal having an electrochemical potential such that it can be deposited on metal M1.
