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. © Pleiades Publishing; Ltd; 2014.
