Silver-Catalyzed C–H Trifluoromethylation of Arenes Using Trifluoroacetic Acid as the Trifluoromethylating Reagent
摘要:
Direct trifluoromethylation of arenes using TFA as the trifluoromethylating reagent was achieved with Ag as the catalyst. This reaction not only provides a new protocol for aryl CH trifluoromethylation, but the generation of CF3 from TFA may prove useful in other contexts and could potentially be extended to other trifluoromethylation reactions.

of difluoro(aryl)-λ3-iodanes (aryl-IF2 compounds) and tetrafluoro(aryl)-λ5-iodanes (aryl-IF4 compounds) using trichloroisocyanuric acid (TCICA) and potassium fluoride (KF). Under these reaction conditions, selective access to either the I(III)- or I(V)-derivatives is predictable based solely on the substitution pattern of the iodoarene starting material. Moreover, the discovery of this TCICA/KF approach
我们报告了一种使用三氯异氰尿酸 (TCICA) 和钾合成二氟(芳基)-λ 3 -碘(芳基-IF 2化合物)和四氟(芳基)-λ 5 -碘(芳基-IF 4化合物)的温和方法氟化物(KF)。在这些反应条件下,仅根据碘芳烃起始材料的取代模式即可预测选择性获得 I( III )-或 I( V )-衍生物。此外,这种TCICA/KF方法的发现促使人们对精心设计的探针分子上的IF 2基团和邻位取代基之间的关系进行了详细的动态NMR、动力学、计算和晶体学研究。正是在这些实验中,揭示了邻位取代基在与TCICA和KF反应期间抑制I( III )-化合物进一步氧化氟化为I( V )-化合物的作用。此外,本文还讨论了这一经验趋势的一个值得注意的例外。
