3-Aryl-1,2,4-benzotriazines were obtained in good yields by the mercury(II) oxide-oxidation of N-phenylsulfonyl-N″-arylbenzamidrazones prepared from N-(phenylsulfonyl)benzohydrazonoyl chlorides and anilines. From the synthetic viewpoint for benzotriazines, this method may be of high utility on account of the availability of starting materials and higher yields.
