Hexafluoropropene trimers, perfluoro-3-ethyl-2,4-dimethylpent-2-ene (1) and perfluoro-3-isopropyl-4-methylpent-2-ene (2) reacted with fluorine under u.v. irradiation to give the new and highly branched perfluoroalkanes perfluoro-2,3,3,4-tetramethylpentane (7) and perfluoro-2,3,4-trimethylpentane (8) through a mechanism involving the elimination-readdition of CF3 groups.Compound (7), which is very bulky, can be easily cleaved at 200 deg C to give two perfluoro radicals capable of initiating the polymerization of vinylic monomers.
