  operationally simple approach to access a wide range of unprecedented and valuable OCF3-containing building blocks. Herein we describe our investigations to elucidate its reaction mechanism. Experimental data indicate that the O-trifluoromethylation of N-(hetero)aryl-N-hydroxylamine derivatives is a radical process, whereas the OCF3-migration step proceeds via a heterolytic cleavage of the N–OCF3 bond followed

  我们小组最近报道的一锅两步分子内芳基和杂芳基C–H三氟甲氧基化提供了一种通用的、可扩展的且操作简单的方法来获得各种前所未有的、有价值的含OCF 3 结构单元。在这里，我们描述了我们的研究，以阐明其反应机制。实验数据表明，N- (杂)芳基-N-羟胺衍生物的O-三氟甲基化是一个自由基过程，而OCF 3 -迁移步骤是通过N-OCF 3键的杂解断裂然后快速重组来进行的。短寿命离子对。计算研究进一步支持了所提出的 OCF 3迁移过程的离子对反应途径。我们希望当前的研究将为使用多功能N- (杂)芳基-N-羟胺合成子开发新的转化提供有用的见解。
