The effects of the substituted halogen, the neighboring groups, and the polarity of the medium on the nature of the fluorination products were studied for the reactions of δ-substituted halogenobutanes and 1,2,3-trihalogenobutanes with bromine tetrachloride.A mechanism involving formation of linear halogenonium ions at the rate-determining stage is proposed.

The conditions were found for selective liquid-phase substitutive fluorination of bromine-substituted alkanes and esters with pure bromine trifluoride, in which all three fluorine atoms of the BrF3 molecule are used effectively in the fluorination.The exchange of bromine for fluorine in monobromohalogenoalkanes is nonstereospecific and is in a number of cases accompanied by skeletal rearrangements, hydride shifts, and migration of the halogen.A carbocationic mechanism of fluorination is discussed.
