Herein, unprecedented rhenium‐catalyzed decarboxylative oxytri‐/difluoromethylation and Heck‐type trifluoromethylation of styrenes have been developed by using hypervalent iodine(III) reagents derived from cheap, stable, and easy‐handling fluorinated carboxylic acids. Mechanistic studies revealed a radical decarboxylative trifluoromethylation pathway occurring in these reactions.
在此,通过使用廉价,稳定且易于操作的氟化羧酸衍生的高价碘(III)试剂,开发出了前所未有的苯乙烯催化的de催化脱羧氧基三/二氟甲基化和Heck型三氟甲基化反应。机理研究揭示了在这些反应中发生的自由基脱羧三氟甲基化途径。
