A comparative study of the electrochemical fluorination (ECF) of 1 ,n-alkanebis (sulfonylfluorides) (n = 1-3 )

Article abstract of DOI:10.1016/S0022-1139(97)00010-9

Synthetic methods for the preparation of α,ω-alkanebis(sulfonylfluorides) and their electrochemical fluorination (ECF) are described in detail. Factors affecting the yield of the perfluoro-α,ω-alkanebis(sulfonylfluorides) are also discussed. Spectral data (¹³C and ¹⁹F NMR and mass spectra) and other hitherto unknown physical properties of difluoromethanebis(sulfonylfluoride) (1), 1,1,2,2-tetrafluoroethane-1,2-bis(sulfonylfluoride) (2) and 1,1,2,2,3,3-hexafluoropropane-1,3-bis(sulfonylfluoride) (3) are measured and compared.
