identical or different halogens is presented. The synthesis is based on the reaction of aryl methyl, aryl halomethyl, or aryl nitromethyl sulfones with sodium hypohalite. The method is simple in implementation, does not necessarily require the use of organic solvents, and selectively affords the products in good to excellent yields. Notably, it allows the preparation of the hitherto unknown phenyl trihalomethyl
提出了一种制备具有相同或不同卤素的芳基三卤代甲基砜(活性杀生物剂)的方法。合成基于芳基甲基,芳基卤甲基或芳基硝基甲基砜与次卤酸钠的反应。该方法实施简单,不一定需要使用有机溶剂,并且选择性地以良好至优异的产率提供产物。值得注意的是,它允许制备迄今未知的具有三种不同卤素的苯基三卤代甲基砜:氟,氯和溴。
