摘　　要：分别采用加氢还原和铁粉还原,对6种含有卤素原子的化合物还原对照。结果显示,催化加氢工艺会发生脱卤反应,而采用铁粉还原的选择性好,产品纯度高。在铁泥能够回收的情况下,铁粉还原法具有重要工业应用价值。In the reduction of six kinds of intermediate with halogen substituents, reductions by Fe and hydrogenation were used, and the results were compared and analyzed. For most reduction reactions concerned, dehalogenation occurred seriously in hydrogenation reaction. Better selectivity was achieved and purer products were prepared in the reduction by Fe. So, reduction by Fe is significant for industrial processes.

关 键 词：铁粉还原 还原方法 脱卤反应
