MARTIN, Erika; TORRENS, Hugo y TOVILLA, Jorge. Sintonas fluoroazufradas. Rev. Soc. Quím. Méx [online]. 2000, vol.44, n.2, pp.108-111. ISSN 0583-7693.
The fluoro-sulfur containing olefines RFSCH2CBr=CH2 RF= 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(SRF)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.
