Ligand-free Zn-catalyzed double carbonylation of aryl iodides with secondary amines: A simple and efficient approach to access α-ketoamides

Abstract

Herein, we report a Zinc catalyzed double carbonylation of aryl iodides 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.
