In the Yamamoto coupling reaction, preferable are organic solvents such as tetrahydrofuran, toluene, 1,4-dioxane, dimethoxyethane, N,N-dimethylacetamide, N,N-dimethylformamide, mixed solvents composed of two or more of them, and the like.
DMF能做的反应,DMAC基本都能做,溶剂的东西,本来就是筛的啊。
楼主麻烦把你的结构贴上来,要合成什么?
不是DMF就是甲苯,没别的溶剂。

感觉可以用dmso试试的啊。。

楼主怎么知道原料在溶剂中变质了呢?我也做这个,没成功,不知道哪里有问题。。。我都是在手套箱里加的,不知道加料顺序是不是有影响?加完原料后是在外边油浴48小时,然后加入浓盐酸甲醇溶液,这个因为想既然浓盐酸里也有水所以就不用无水无氧了吧?直接在通风橱里倒进去的。后来得到的产物不对...求解释
你知道这个反应最后为什么要加入盐酸吗
