Abstract
A suitable route for the preparation of 4H-1,4-benzothiazine sulphones
with hydrogen peroxide and acetic acid has been reported. The synthesis of
4H-1,4-benzothiazines, consisting of 2-aminothiophenol with β-diketone/
β-ketoester in dimethyl sulphoxide, is described. The infrared spectral
investigation on the pure samples of 4H-1,4-benzothazines and its sulphones
showed the remarkable shifting of characteristic vibrational bands
towards higher frequencies in sulphones.
