A domino reaction that involves the formation of CS and C–N bonds in one process via sp3 C–H functionalization strategy has been developed. This reaction affords an efficient and direct method for the synthesis of α-ketothioamides fromaryl methyl ketones, amines, and sodium hydrosulfide under the promotion of iodine.

We have developed a practical, general protocol from readily available phenacyl sulfoxides bearing tetrazoles with amines to access a broad scope of α-ketothioamides under mild conditions. The reaction has good substrate applicability, and provides an efficient, green and convenient method for the preparation of α-ketothioamide compounds under metal-, oxidant- and catalyst-free conditions.
