Covalent triazine framework-supported palladium as a ligand-free catalyst for the selective double carbonylation of aryl iodides under ambient pressure of CO
Carbonylation of aryl iodides with amines at atmospheric pressure of CO, catalyzed by Pd/CTFs (covalent triazine frameworks) without any specific additives, leads to the highly selective synthesis of [small alpha]-ketoamides.
Abstract Herein, we report a Zinc catalyzed double carbonylation of aryliodides with secondary amines under CO pressure for the synthesis of α-ketoamides in good to excellent yields. This methodology provides a simple and economic approach to derivatize useful α-ketoamides.
摘要 在此,我们报道了在 CO 压力下锌催化芳基碘化物与仲胺的双羰基化反应,以良好至优异的产率合成 α-酮酰胺。该方法提供了一种简单且经济的方法来衍生有用的 α-酮酰胺。
