The process was methanolysis α-imino ether acid hydrogen chloride salt from methyl-cyanide.

研究了以乙腈为原料经α-亚氨基乙醚盐酸盐醇解制备原醋酸二乙酯的工艺方法，对醇解的投料比、反应时间及中和pH值等工艺条件进行了研究，得出较优惠的工艺条件。

We have developed a simple and easy-handling procedure for copper-catalyzed cyanation of aryl halides using K4[Fe_6] as the cyanide source. The present procedure has ligand- and base-free advantages, and was accomplished under the conditions of exposure to the air without degassing of the solvent.4. We carried out the selective control of preparation for phenyl ether and phenol from iodobenzene with 10 mol% of Cu_2·H_2O as the catalyst under the condition of exposure to air.

这个程序有无配体无碱的好处，并能够在暴露于空气的条件下进行，溶剂也不用脱气。4、空气气氛下，用10 mol%的Cu_2·H_2O催化碘苯偶联，实现了制备二苯醚和苯酚的选择性控制：即在有(来源：Aa955BC55论文网www.abclunwen.com)机溶剂NMP中实现了碘苯直接制备二苯醚的Ullmann反应，在H2O中实现了碘苯直接制备苯酚。
