以水合肼作为氢源,以T-1型雷尼镍作为催化剂,常压的条件下,在沸腾的甲醇中顺利地还原脂肪族硝基为氨基制备了Behera胺,反应时间短,易于操作,可以替代现有的合成方法.并制备了第二代树枝形硝基化合物4,用同样的方法还原4得到第二代树枝形Behera胺. With hydrazine hydrate as a hydrogen source and T-1 type Raney nickel as a catalyst, Behera amine is prepared by smoothly reducing an aliphatic nitro group into an amino group in boiling methanol under normal pressure. The reaction time is short and the operation is easy. Can replace the existing synthesis method and the second generation of dendritic nitro compound 4 was prepared, and the same method was used to reduce 4 to obtain the second generation of dendritic Behera amine.
