摘要

研究人员利用 Togni 试剂 II，在室温和 fac-Ir(PY)3存在的条件下，提出了一种在可见光诱导下使 1,2-苯并恶唑的 C-4 位发生 C-H 三氟甲基化反应的新方案。这种方法具有操作简单、效率高和特异选择性等特点。

Visible-light-induced Ir-catalyzed site-selective C−H trifluoromethylation of 3-substituted 1,2-benzoxazoles

A new protocol for visible-light-induced C–H trifluoromethylation at C-4 position of 1,2-benzoxazoles has been disclosed with Togni reagent II at room temperature in the presence of fac-Ir(ppy)₃. This approach features simple operation, high efficiency, and specific selectivity.
