The fluoro-sulfur containing olefines R_FSCH₂CBr=CH₂ R_F= C₆F₅ 1, C₆HF₄-2,3,5,6 2, C₆H₄F-2 3, C₆H₄F-3 4, C₆H₄F-4 5 and C₆H₄(CF₃)-3 6 have been prepared by treatment of BrCH₂CBr=CH₂ with the corresponding Pb(SR_F)₂. Characterisation of these new compounds was carried out using 1H and 19F NMR, FAB+ mass spectrometry, elemental analysis and IR spectroscopy. For all the compounds synthesised, further bromine substitution in subsecuent reactions was suggested by FAB+ mass spectrometry.

Palabras llave : Fluorine; sulfur; fluorinated thioethers; fluorinated olefins.
