The Reactions of the Dimers of Hexafluoropropene with O-Nucleophiles

The reactions of the dimers of hexafluoropropene with alcohols and phenol in the presence of triethylamine, and with sodium alkoxides and phenolate were carried out. Of the two dimers, perfluoro-2-methyl-2-pentene (Dimer 2) was much more reactive than perfluoro-4-methyl-2-pentene (Dimer 1). While the dimer 2 and O-nucleophiles gave various addition and substitution products very easily, the dimer 1 reacted only with sodium alkoxides to give trialkoxylated products.
