dihydropyridazino[3,4-b]quinoxalines, the structure of which has been ascertained. It has been shown that among the six possible formulas, the only 1,2-dihydro structure fits with the spectroscopic data. On the contrary, N-substituted o-phenylenediamines lead to 2,10-dihydro derivatives. The electrochemical behavior of the 2,10-dihydro-10-methyl-3-phenylpyridazino[3,4-b]quinoxaline has been investigated
邻苯二胺与β-酮酸的反应在大多数情况下导致喹喔啉酮。已经确定了它们的结构以及相应的的结构。肼与这些喹喔啉酮的反应得到二氢哒嗪[3,4- b ]喹喔啉,其结构已经确定。已经表明,在六个可能的分子式中,仅有的1,2-二氢结构与光谱数据吻合。相反,N-取代的邻苯二胺导致2,10-二氢衍生物。研究了2,10-二氢-10-甲基-3-苯基哒嗪并[3,4- b ]喹喔啉的电化学行为。还显示了3,4,6-三氯哒嗪与邻苯二胺得到5,10-二氢吡啶并[3,4- b ]喹喔啉。这些化合物可以被氧化,得到新的杂环哒嗪并[3,4- b ]喹喔啉。
