pentachloride (the Freundler reaction) has been shown to give four major products: 8-chloroindazolo[2,3-a][3,1]benzoxazin-5-one, 2-chloroindazolo-[2,1-a]indazole-6,12-dione, 10-chloroindazolo[2,3-a][3,1]benzoxazin-5-one (α and β modifications), and a minor product, indazolo[2,1-a]indazole-6,12-dione. The structures were assigned on the basis of independent syntheses, chemical behaviour, and spectroscopic
用五氯化磷处理偶氮苯-2,2'-二羧酸(弗氏反应)已显示出四种主要产物:8-氯吲唑[2,3- a ] [3,1]苯并恶嗪-5-one,2 -氯吲唑- [2,1 - a ]吲唑-6,12-二酮,10-氯吲唑[2,3- a ] [3,1]苯并恶嗪-5-酮(α和β修饰)和次要产品,吲唑并[2,1 - a ]吲唑-6,12-二酮。根据独立的合成,化学行为和光谱检查对结构进行分配。
