IMINATION OF SULFUR-CONTAINING COMPOUNDS. XXIV. EFFECT OF THE ACIDIC CHARACTERISTICS OF THIOLS ON THE IMINATION OF SODIUM THIOLATES BY DICHLOROSULFONAMIDES

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.
