o)indole-2,6-dione 5 respectively. Stirring 2-aryl-1,4-benzoquinones (1) with ethylenediamine and/or o-phenyl-enediamine in methylene chloride gives pyrazino[2,3-g]quinoxalines derivative 6 and/or tetrapentacene derivative 7 respectively. The products 5-aryl- and 6-aryl-1/H-indazole-4,7-diones 8 and 9 were obtained in the 1,3-dipolar cycloaddition of diazomethane to (1).
用不同的酰氯,即乙酰氯,苯乙酰基和氯乙酰氯处理2-芳基-3,6-双(芳基氨基)-1,4-苯醌2a-h,得到3a,7a-二氢吡咯并[2,3- f ]吲哚- 2,6-二酮3,5-(N-苯基乙酰基芳基氨基)-3-苯基吲哚-2,6-二酮4和3-氯-5-(N-氯乙酰基芳基氨基)吲哚-2,6-二酮5。将2-芳基-1,4-苯醌(1)与乙二胺和/或邻苯基-二烯胺在二氯甲烷中搅拌,分别得到吡嗪并[2,3- g ]喹喔啉衍生物6和/或四并五苯衍生物7。产品5-芳基和6-芳基-1 / H在(1)的重氮甲烷的1,3-偶极环加成中获得-吲唑-4,7-二酮8和9。
