New derivatives of photochromic 2-aryl-1-(4-nitrophenyl)-1,1a-dihydroazireno[1,2-a]quinoxalines were synthesized by condensation of 4-methyl-and 4,5-dimethyl-1,2-phenylenediamine with 1,3-diaryl-2,3-dibromopropan-1-ones. The reactions of 4-methyl-1,2-phenylenediamine produce mixtures of regioisomers. The chemical properties of the reaction products were studied. The structure of one of the latter was established by X-ray diffraction.
通过将4-甲基-和4,5-二甲基-1,2-苯二胺与1,3-二芳基-2,3-二溴丙烷-1-酮缩合,合成了光致变色2-芳基-1-(4-硝基苯基)-1,1a-二氢氮杂环庚烯并[1,2-a]喹喔啉的新衍生物。4-甲基-1,2-苯二胺的反应产生了多种区域异构体混合物。对反应产物的化学性质进行了研究。其中一种反应产物的结构通过X射线衍射确定。
