• Perfluoro-4-methyl-1,3-dioxole: a new monomer for high-Tg amorphous fluoropolymers

  A 4-Chloro-5-trifluoromethyl-2,2,4-trifluoro-1,3-dioxolane (1) was synthesised by reaction of CF2(OF)(2) with CF3-CH=CFCl; the elimination of HCl from (1) in basic conditions led to the formation of dioxole perfluoro-4-methyl-1,3-dioxole (2). Both these synthetic steps gave the corresponding product in high yield.A new synthetic route for the preparation of CF3-CH=CFCl, starting from CF2ClBr and CH2=CF2, together with some examples of polymerisation products obtained by reaction of dioxole (2) with fluoroolefins are also reported.

  We have studied the dehalogenations of halofluorinated alkanes and fluorinated ethers, both linear and cyclic, as well as halofluorinated alkanes containing an aromatic moiety, to their corresponding unsaturated species in a biphase fluorinated/hydrogenated solvent system.
