EFFECT OF STRUCTURE ON THE KINETICS AND MECHANISM OF THE ACID-CATALYZED DECOMPOSITION OF N-ALKYL-N-NITROBENZENESULFONAMIDES

The decomposition rate of a series of meta- and para-substituted N-alkyl-N-nitrobenzenesufonamides was determined by a spectrophotometric method in aqueous sulfuric acid.It was shown that the decomposition of the compounds takes place both by denitration and by cleavage of the N-S bond with the formation fo primary aliphatic N-nitrosamines.Electron-withdrawing substituents in the aromatic ring shift the process toward denitration.

EFFECT OF STRUCTURE ON THE KINETICS AND MECHANISM OF THE ACID-CATALYZED DECOMPOSITION OF N-NITROBENZENESULFONAMIDES

The decomposition rate of a series of ring-substituted N-nitrobenzenesulfonamides in aqueous sulfuric acid was measure by a spectrophotometric method.Decomposition of the compounds takes place both by the cleavage of the N-S bond to form the corresponding sulfonic acid, nitrous oxide, and water and by denitration.In crease in the electronegativity of the substituent in the aromatic ring promotes the denitration reaction.
