  摘要：

  羟基(H2O)-偶氮氧基-和偶氮芳烃是通过ArN(MgBr)2与邻-、间-和对-HO-硝基苯缩合形成的；核替代作为次要或主要途径发生。以足够高的收率获得邻-HO-偶氮苯。产物的相对收率根据HO基团的位置和反应条件而变化。产率变化可以通过单电子转移的相对效率、σ-络合和试剂分子合作的影响来解释。

  Hydroxy(HO)-azoxy- and -azoarenes were formed by condensation of ArN(MgBr)2 with o-, m-, and p-HO-nitrobenzenes; nuclear substitution took place as a minor or a major pathway. o-HO-azobenzene was obtained in sufficiently high yield. Relative yields of the products varied according to the position of HO group and reaction conditions. The yield variation was explained by the effects of relative efficiency
