Oligomers of vinyl phosphonic acid obtained by radical polymerization in the presence of halogenated chain transfer agent

Two halogenated compounds, ICFCICF2Cl et BrCF 2CFCl-Br, were synthesized and characterized and were further used as chain transfer agents (CTAs) for the radical polymerization of vinyl phosphonic acid (VPA). Only BrCF2CFClBr was efficient CTA towards VPA as the chain transfer constant CT value of 1 was evaluated. This value clearly demonstrates that the chain-end of each VPA polymeric chain is BrCF 2CFCl group, which will allow to perform a dehalogenation from this group, leading to a new VPA macromonomer. Hence, VPA telomere were synthesized with Mn values ranging from 1800 to 6700 g/mol.

Perhaloethyl aromatic compounds and perhaloethenyl aromatic compounds therefrom

A synthesis is provided for α,β-difluoro-β-halo-ethenyl aromatic compounds such as α,β,β-trifluorostyrenes by a process of reacting CFX2CFXI, wherein each X is independently F or Cl, provided that at least one X is Cl and at least one X is F, with an aromatic compound Ar to form (CFX2CFX)n—Ar, wherein n is 1, 2 or 3, and subsequently dechlorohalogenating this product to form (CFX═CF)n—Ar. Novel synthetic intermediate compounds are provided.

REACTION OF 2,2-DICHLOROTRIFLUORO-1-IODOETHANE WITH ZINC

The zinc coupling reaction of a pure sample of 2,2-Dichlorotrifluoro-1-iodoethane (I) in acetic anhydride-methylene chloride has been investigated.The coupled product C4F6Cl4 was found to be a single isomer by 19F NMR and had the structure CFCl2CF2CF2CFCl2 (II).The probable modes of formation of by-products such as C6F9Cl5 and C8F12Cl6 are discussed.
