4-溴邻苯二胺的合成

Synthesis of 4 Bromo Phenylenediamine

采用两条路线合成４溴邻苯二胺，并对路线（Ⅱ）中水解一步作了探讨这两条路线是：１．用漆原镍催化氢化 ４溴２硝基苯胺；２．邻苯二胺溴化后，碱水解中间体 Ｎ， Ｎ（４溴１。

4 Bromo 1,2 phenylenediamine was prepared by two methods. One is the hydrogenation of 4 bromo 2 nitroaniline catalyzed by Urushibara nickel. The other is the alkaline hydrolysis of N,N (4 bromo 1,2 phenylene)bisacedamide obtained from bromination of 1,2 phenylenediamine.
