such as hydroxyl and amine groups could be conveniently reduced with 3 molar equivalents of hydrazine hydrate in presence of Raney nickel catalyst in ethanol/1,2-dichloroethane solvent mixture to give a product wherein one of the two nitro groups was reduced to the amino group. The yields of the partial reduction products are good. Under similar conditions alkoxyl substituents in the o,p-position to the
在阮内镍催化剂的存在下,在乙醇/1,2-二氯乙烷溶剂混合物中,含有羟基和胺基等取代基的二硝基芳烃可以方便地用 3 摩尔当量的水合肼还原得到产物,其中两个硝基之一被还原为氨基。部分还原产物的收率良好。在类似条件下,硝基 o,p 位的烷氧基取代基被肼基取代,得到 2,4-二硝基苯肼作为主要产物。描述还原反应的细节。
