Synthése de nouveaux intermédiaires F-alkyles précurseurs de tensioactifs cationiques hautement fluorés
摘要:
The syntheses of F-alkyl compounds such as(~)[GRAPHICS](~)(where R(F) = C4F9, C6F13, C8F17 and Q = S, O, NH) by the reaction of bromoacetyl bromide with an F-alkyl compound such as RFC2H4QH are reported. These compounds show high reactivity with nucelophilic substrates. They are intended for use as precursors of surfactants or as precursors of monomers for the elaboration of artificial vesicles.

The replacement of iodide in 2-perfluoroalkyl-1-iodoethanes by anions derived from dialkyl malonate affords α-(2-perfluoroalkyl)ethyl malonic esters in high yields with negligible elimination and dialkylation, using bases such as K2CO3 or NaH in THF. The physical properties of the products are described.
