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.
Coupling between a fluorinated olefin and a perfluorinated iodide: A model study on the reaction mechanism of perfluorinated polymer cross-linking

In a model study, 1H, 19C, 13 C-1H and 1H-1H correlated NMR techniques confirm a Markovnikov type reaction intermediate for the major coupling products between a short, low MW perfluorinated iodide C2F5I (I) and a short, low MW fluorinated olefin CF3(CF2)7CH=CH2 (II). The reaction is peroxide induced (di-t-butyl peroxide, DTBP) and is conducted at 140 °C for a 3 h reaction time in a sealed glass ampoule. Side reaction products due to the reaction of DTBP with radical reaction intermediates were also observed and identified. The study aimed to mimic as closely as possible the peroxide-initiated coupling reaction between an iodine terminated fluoropolymer (model compound I) and its fluorinated di-olefin coupling agent (model compound II). A mono-olefin was chosen to simplify the model reaction.

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
Molines, Huguette,Tordeux, Marc,Wakselman, Claude
, p. 367 - 368 (2007/10/02)
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.
