An oxidative dehydrogenative coupling of thiols with alkanes via direct C(sp 3 )−H bond functionalization to form a new C−S bond and S� O double bond was developed. The present reaction features the use of readily available reagents and high step-and atom-efficiency, thus providing an efficient access to sulfoxides. A possible mechanism is proposed.

A copper-catalyzed cascade multicomponent reaction for synthesizing ditriazolyl diselenides from azides, terminal alkynes, and elemental selenium has been developed. The present reaction features utilizing readily available and stable reagents, high atom-economy, and mild reaction conditions. A possible mechanism is proposed.

A radical bicyclization of 2-cyanoaryl acrylamides with dicumyl peroxide has been developed for constructing a broad spectrum of benzo[h]naphtho [1,8-bc][1,6]naphthyridine. This reaction allows the formation of three new chemical bonds through addition of methyl radical across alkene double bond, intramolecular addition of carbon-centered radical to cyano group and cyclization of the iminyl radical cascade, and features simple reaction system and wide substrate scope.
