The ability of sodium thiolates to be iminated by dichlorosulfonamides is due to a series of factors and primarily to the acidic characteristics of the initial thiols.The sodium salts of thiols with pKa > 8 are iminated comparatively readily by dichlorosulfonamides.Decrease in the pKa values of the thiols to 5-7 leads to a decrease in the imination rate and in the yields of the respective N,N'-bis(arylsulfonyl)sulfinamidines.The sodium salts of thiols with pKa 5 are not iminated by dichlorosulfonamides.Investigation of the acidic characteristics of the N,N'-bis(arylsulfonyl)sulfinamidines showed that substituents in the sulfinamidine fragment of the molecule make a larger contribution to the change in the acidic characteristics of the compounds than substituents in the arenesulfonyl fragment.

Disulfides react with chloramine T in alcohols to give a mixture of N-tosylamides and alkyl esters of N-tosylalkane- or N-tosylarene-sulfinimidic acids.
