Perfluoroalkyl chains in solids are highly disordered in a wide range of temperatures. Poor attention is typically given to this problem in crystallographic studies to the point that no attempt is frequently made in order to model the collected data

Tetrafluoroethylene telomerization using dibromohaloethanes as telogens

Autor: Ivan Wlassics, Vito Tortelli

Publikováno v: Journal of Fluorine Chemistry. 127:240-248

Carrier mediated telomerization (CMT) between C 2 F 4 and bromochlorofluoroethanes has been evaluated in terms of product distributions arising from CMT and ‘normal’ telomerization. The effect of parameters like type of initiator and telogen, TFE

2π + 2π cycloaddition kinetics of some fluoro olefins and fluoro vinyl ethers

Autor: Ivan Wlassics

Publikováno v: Journal of Fluorine Chemistry. 125:1519-1528

The second order 2π + 2π homo- and co-dimerization between various classes of fluorinated olefins has been investigated. The fluorinated olefins examined in this study were: (1) Rf OCF CF2 (perfluorinated vinyl ethers); (2) Rf CF CF2 (perfluorinate

Perfluopolyether (PFPE) (poly)diacyl peroxides: synthesis and applications

Autor: Donato Montrone, Vito Tortelli, Ivan Wlassics, Marco Sala

Publikováno v: Journal of Fluorine Chemistry. 121:65-74

This paper deals with the synthesis of perfluoropolyether (PFPE) (poly)diacyl peroxides with mean EWs ranging from 500 to 4000 g eq.−1 via H2O2 and base from the corresponding PFPE diacyl halides, their decomposition (thermal and hydrolytic) and th

Perfluoroalkyl radicals, generated by thermal decomposition of perfluorodiacyl peroxides, react selectively with quinone rings of 1,4-naphthoquinones. In the presence of a non-conjugated alkene such as 1-hexene, perfluoroalkyl radicals add to the dou
