By use of the condensation reaction of aryliminodimagnesium reagents (ArN(MgBr)2) with nitroarenes, six symmetrical and eight unsymmetrical azoxyarenes including four pairs of isomers were prepared in 40–80% yields. The deoxygenation reaction of the azoxyarenes by treating with five molar equivalents of p-MeOC6H4N(MgBr)2 at 55 °C in tetrahydrofuran was also studied, and the reactivity of deoxygenation
通过使用芳基氨基二镁试剂 (ArN(MgBr)2) 与硝基芳烃的缩合反应,以 40-80% 的产率制备了包括四对异构体在内的六个对称和八个不对称氧化偶氮芳烃。还研究了在 55 °C 下在四氢呋喃中用 5 摩尔当量的 p-MeOC6H4N(MgBr)2 处理氧化偶氮芳烃的脱氧反应,脱氧反应的反应性与氧化偶氮芳烃的电子吸收最大值的移动相关。
