The copper-mediated direct arylation of 1,3,4-oxadiazoles and 1,2,4-triazoles with aryl iodides proceeds efficiently in the presence of suitable ligands and bases. This method allows the installation of a variety of aryl moieties bearing a functional group such as ketone, ester, or nitrile so as to enable the facile construction of various functionalized oxadiazole and triazole core π systems.
在合适的配体和碱的存在下,铜介导的1,3,4-恶二唑和1,2,4-三唑与芳基碘的直接芳基化反应有效进行。该方法允许安装带有诸如酮,酯或腈之类的官能团的各种芳基部分,从而使得能够容易地构建各种官能化的恶二唑和三唑核π系统。
