Lead/ammonium acetate is a convenient reagent for the reduction of aromatic nitro compounds to the corresponding symmetrically substituted azo compounds. Various azo compounds containing additional reducible substituents such as halogen, nitrile, acid, phenol, ester, methoxy, etc., functions have been synthesized in a single step by the use of this reagent. The conversion is reasonably fast, clean,
摘要 醋酸铅/铵是一种方便的试剂,可用于将芳香族硝基化合物还原为相应的对称取代的偶氮化合物。使用该试剂一步合成了各种含有额外的可还原取代基如卤素、腈、酸、苯酚、酯、甲氧基等功能的偶氮化合物。转化相当快、干净、产率高,并且在室温下在甲醇中发生。
