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.

A series of quinoxaline-2-thiols and quinoxalines were prepared in moderate to good yields from various phenacyl sulfoxides bearing 1-methyl-1H-tetrazole and o-arylenediamines. The proposed reaction mechanism involves generation of sulfines from the phenacyl sulfoxides bearing 1-methyl-1H-tetrazole through thermolysis elimination. Then, site-selective carbophilic addition of sulfines by o-arylenediamines
Manganese triacetate is introduced as a new reagent to replace potassiumferricyanide or bromine for radical cyclization of substituted thioformanilides. 2-Substituted benzothiazoles are generated in 6 min under microwave irradiation.
