It can be freshly prepared by dissolving an appropriate quantity of CuI in boiling saturated aqueous NaI over 30minutes. Pure CuI is obtained by cooling and diluting the solution with water, followed by filtering and washing sequentially with H2O, EtOH, EtOAc, Et2O and pentane, then drying in vacuo for 24hours [Dieter, J Am Chem Soc 107 4679

建议lz多看看常用有机化学试剂的提存方法,
我是做一价铜配合物的,都是从CuI起始,强烈建议抽真空N2保存,否则很容易氧化,而且我发现一旦有一小部分被氧化我的反应就不好
这个最好真空保存,但是还是建议楼主现用现制备,这样的碘化亚铜活性高。
啊?我们实验室的都是一大罐买回来直接放在外面的,好像都没啥问题,用来做反应也没问题。。。。。
还挺稳定的吧,我们实验室经常做一些偶联反应,直接用的就是500g包装的
