Preparation, crystal structure and microwave studies on ring-substituted arylammonium hydrogen sulfate salts

Three ring substituted arylammonium hydrogen sulfates (RSAHS)/ring substituted dianilinium sulfates (RDAS) have been prepared from corresponding arylamines by treatment with excess conc. H2SO4 and characterized by X-ray crystallography, elemental, gravimetric and spectral analyses. The RSAHS/RDAS salts yield the corresponding ring substituted amino benzene sulfonic acids (RSABSA) when subjected to microwave irradiation. It is observed that these salts undergo transformation to acid in solid state via proton transfer reaction prior to sulfonation.
