Abstract

Abstract The reaction of substituted anilines and benzenesulfonyl chlorides has been used to prepare 49 substituted N-phenylbenzenesulfonamides of general formula 4-XC 6 H 4 SO 2 NHC 6 H 4-Y-4'. Their purity was checked by elemental analysis. The substituents X and Y include H, CH 3, CH 3 O, Cl, Br, CN, and NO 2. The dissociation constants of all compounds were determined by potentiometric titration in methanol, acetonitrile, N, N- ...
