aromatic ring. Secondary sulfonamides, 5l, 5m, and 5n showed activities that were proportional to their lipophilicity. The activities of N‐aryl‐substituted derivatives 5j, 5k, 5l, 5m, 5n, and 6j were also proportional to their lipophilicity. Halogenation enhanced the activity as a result of improvement of lipophilicity. The presence of two imidazole or triazole rings in the same compound did not show

The kinetics of arenesulfonylation of N-methyl- and N-ethylaniline with 3-nitro- and 4-methylbenzenesulfonyl chlorides in aqueous 1,4-dioxane have been studied. Comparison of the solvent effects on the reaction of N-alkylanilines with arenesulfonyl chlorides has revealed higher yields of the arenesulfonylation products (more than 90%) in water-1,4-dioxane mixtures over a wide range of solvent composition as compared to water-alcohol mixtures studied previously.

Fundamental kinetic aspects of the arenesulfonylation of N-alkylated anilines in aqueous-organic media, the nonaqueous component of which are alcohols, ethers, and acetonitrile were studied. It was shown that, with increasing fraction of water in the solvent, the reaction rate constant grows and the reactivity of N-alkyl anilines depends not only on the structure of the alkyl radical, but also on the content of water in the solvent. It was found that dimethyl sulfoxide has a catalytic effect on these processes. The strategy of choosing the medium in syntheses of biologically active sulfonyl derivatives of fatty-aromatic amines is discussed. A conclusion about the applicability of aqueous-organic media in the production technology of N-alkylated anilines is based on a calculation of the yield of their arenesulfonylation products.
