Copper(II) efficiently catalyzes the aerobic oxidation of aryl thioacetamides into the corresponding α-keto aryl thioamides in moderate to high yields in the presence of K2CO3 under O2 atmosphere. This protocol is simple, clean, and generates water as the only byproduct. A mechanism is proposed for the reaction course.

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.

The Willgerodtreaction under iron-catalyzed aerobic conditions was found to be an excellent tool for full α-heterofunctionalization of acetophenones with sulfur and amines. Via this break-and rebuild strategy, a wide range of thioglyoxamides was synthesized in a four-component, highly atom-, step- and redox-economical manner with water as the only by-product.

α-azido ketones with elemental sulfur could form α-ketothioacyl azide, which was then nucleophilically attacked by amines, causing the cleavage of the C-N bond to afford α-ketothioamides, while amides could be formed with the release of nitrogen gas and cyano anion in the presence of PhI(OAc)2 by selective C-C bond cleavage.
