A chemoselective reductive coupling of nitroarenes using magnesium in methanol has been reported at ambient temperature. While the cyano, formyl, methoxycarbonyl, methyl, methoxy, phenyl, amino, and chloro groups are unaffected, iodo and bromo groups undergo dehalogenation but in a slower reaction than the coupling of nitro group. The coupling is believed to be proceeding via SET from Mg to nitroarenes
已经报道了在环境温度下使用甲醇中的镁进行硝基芳烃的化学选择性还原偶联。虽然氰基、甲酰基、甲氧基羰基、甲基、甲氧基、苯基、氨基和氯基团不受影响,但碘基和溴基团进行脱卤,但反应比硝基偶联慢。据信偶联是通过 SET 从 Mg 进行到硝基芳烃的。
