A mild and efficient copper‐catalyzed intramolecular carbotrifluoromethylation of alkynes has been achieved in the presence of Togni reagent as trifluoromethylating reagent. The reaction tolerates a range of substrates to give a group of trifluoromethylated heterocycles with high selectivities. A plausible mechanism was proposed on the basis of experimental results.
在存在作为三氟甲基化试剂的Togni试剂的情况下,已实现了温和有效的铜催化炔烃分子内碳三氟甲基化反应。该反应容许一定范围的底物,以产生具有高选择性的一组三氟甲基化的杂环。根据实验结果提出了一个合理的机制。
