Both molecular iodine and hydrosilane are compounds that are easy to store and access, and the reactions involving them have the characteristic of simple operation. In this work, diiodine/hydrosilane system is used for the synthesis of α-hydroxyamides. α-Ketoamides are used as the raw materials with chlorodimethylsilane serving as the hydrosilane, and the solvent is ethyl acetate. The synthesis can be achieved within 40 min at room temperature. This synthesis method is easy to operate, and has a short reaction time, a wide range of substrate scope and good functional group tolerance. A total of 22 α-hydroxyamide products were obtained, and a gram-scale experiment was conducted using 2-oxo-2-phenyl-N-(p-tolyl)aceta- mide as the starting material.

Key words: molecular iodine, hydrosilane, chlorodimethylsilane, α-hydroxyamides
