A Novel Synthesis of 3-Aryl-1,2,4-benzotriazines via N-Phenylsulfonyl-N''-arylbenzamidrazones

Article abstract of DOI:10.1246/bcsj.55.859

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.
