【摘要】 2条路线合成了5,14-二氢-5,7,12,14-四氮并五苯。分离得到三氯化铁氧化邻苯二胺的氧化产物,副产物被证明能生成5,14-二氢-5,7,12,14-四氮并五苯。相比较第一条路线收率更高,是合成5,14-二氢-5,7,12,14-四氮并五苯的首选。更多还原

【Abstract】 5,14-Dihydro-5,7,12,14-tetraazapentacene(5)was synthesized in two modified routes.One was started from 1,2-diaminobenzene(route-1)and the other from p-hydroquinone(route-2).Results showed that the route-1 should be the first choice for the synthesis of 5 because of its higher yield.3-Amino-2-hydroxy dibenzopyrazine,the by-product from the oxidation of diaminobenzene in route-1,was also isolated and converted into 5.更多还原
