The reaction of dimethyl sulfoxide–trifluoroacetic anhydride complex with anilines, phenols, and thiophenols was studied, and the following results were obtained. (1) The yields of a methylthiomethylated product were improved with anilines. The reaction proceeded without significant amount of tar, the unreacted anilines being easily recovered. (2) Selective ortho-methylthiomethylation took place with
研究了二甲基亚砜-三氟乙酸酐与苯胺、苯酚和苯硫酚的反应,得到以下结果。(1) 苯胺提高了甲硫基甲基化产物的产率。反应在没有大量焦油的情况下进行,未反应的苯胺很容易回收。(2) 酚类在较低温度下发生选择性邻甲硫基甲基化,产率较高,对甲硫基甲基化发生在较高温度。(3) 在室温下,苯硫酚的硫原子上的苯硫酚在一个简单的过程中发生了甲基硫代甲基化反应。
