Abstract Azo compounds are conveniently reduced to either partially reduced hydrazo compounds or completely reduced anilines by employing Raney nickel in presence of hydrazinium monoformate depending upon reaction conditions. The other reducible moieties like ‒COOH and halogens are tolerated. The reduction process is selective, rapid and high yielding.
摘要 根据反应条件,通过在单
甲酸肼鎓存在下使用雷尼
镍,可以方便地将偶氮化合物还原为部分还原的偶氮化合物或完全还原的
苯胺。可以容忍其他可还原部分,如 ‒COOH 和卤素。还原过程具有选择性、快速和高产。
