报道了由芳胺合成1，3-二芳基三氮烯和偶氮染料的新方法。这两种方法都涉及通过芳胺与N-亚硝基磺酰胺的转亚硝化反应形成芳基重氮中间体。每个两步转化可以在室温下在一个反应容器中进行，不采取排除空气或水分的预防措施。几个三氮烯和偶氮染料的结构在这里报道的第一次，表明在温和的条件下操作的两步反应序列的实用程序。
New methods for the synthesis of 1,3-diaryltriazenes and azo dyes from aryl amines are reported. Both methods involve the formation of aryl diazonium intermediates via the transnitrosation of aryl amines withN-nitrososulfonamides. Each two-step transformation may be performed in one reaction vessel at room temperature with no precautions taken to exclude air or moisture. Several triazene and azo dye structures are reported here for the first time, demonstrating the utility of operating the two-step reaction sequence under mild conditions.
