The rhodium(III)‐catalyzed ortho CH alkynylation of non‐electronically activated arenes is disclosed. This process features a straightforward and highly effective protocol for the synthesis of functionalized alkynes and represents the first example of merging a hypervalent iodine reagent with rhodium(III) catalysis. Notably, this reaction proceeds at room temperature, tolerates a variety of functional
公开了铑(III)催化的非电子活化芳烃的邻位CH炔基化反应。此过程的特点是用于合成官能化炔烃的直接有效的方法,代表了高价碘试剂与铑(III)催化合并的第一个示例。值得注意的是,该反应在室温下进行,耐受各种官能团,更重要的是,对单炔基化显示出高选择性。
