The super electrophilicity of a shelf-stable, easily prepared trifluoromethylthiolating reagent N-trifluoromethylthio-dibenzenesulfonimide 7 was demonstrated. Consistent with the theoretical prediction, 7 exhibits reactivity remarkably higher than that of other known electrophilic trifluoromethylthiolating reagents. In the absence of any additive, 7 reacted with a wide range of electron-rich arenes
证明了耐贮存的,容易制备的三氟甲基硫醇化试剂N-三氟甲基硫基-二苯磺酰亚胺7的超亲电子性。与理论预测一致,7的反应活性明显高于其他已知的亲电子三氟甲基硫醇化试剂。在不存在任何添加剂的情况下,7在温和条件下与多种富电子芳烃和活化杂芳烃反应。同样,可以通过简单地改变反应溶剂来微调7与苯乙烯衍生物的反应,从而以高收率产生三氟甲硫基化的苯乙烯或羰基三氟甲硫基或氨基三氟甲硫基二官能化的化合物。
