Abstract

Addition reactions of pentafluorosulfur bromide with unsaturated substrates were studied and four new compounds containing the pentafluorosulfur group have been prepared.

The mechanism for these reactions seems to involve a radical addition pathway. In reaction with CH₂=CFC1, CF₃C≡CH and CH₃C≡CH the SF₅ radical attacks the carbon atoms carrying the most hydrogens. The reaction with CF₂=CHCl is interesting, as by analogy with other fluoroolefins, the SF₅ primary attack should occur.at the CHCl group, however, SF₅CF₂CHC1Br was found as the only product for this reaction. The reaction of SF₅Br with CF₃C≡CH produced two isomers but with CH₃C≡CH only one isomer was forrmed.

Analytical data, infrared, nmr .and mass spectra are presented supporting the proposed structures for these new compounds.
