Interhalogen selectivity

Preparation of Compounds Labeled with Tritium and Carbon-14 Interhalogen Selectivity... 

Because the cation characteristic of the solvent is IF4+, it is reasonable to assume that the ion may have some existence in other situations. As with the other polyatomic ions shown so far, the reaction selected involves a strong Lewis acid such as SbF5 to remove l , and the same approach is taken for producing C1F4+ and BrF4+ in the interhalogen solvents.

Numerous compounds of this sort are known. The selection given here—with the exception of KI3 H3O and HICl. 4H3O—is so chosen that to each of the previously described interhalogen compounds there corresponds a polyhalide which yields that compound on decomposition.

After the usual sections on the history of the discoveries of and the application of the network to the halogens, special sections on (1) the oxoacids and their salts and (2) the interhalogens follow. The section on reactions and compounds of practical importance comes next and finally the selected topic in depth, which concerns the threat posed by chlorofluorocarbons to the ozone layer.
