A direct electrochemical oxidative cyclization of activated alkynes with diselenides or disulfides toward functionalized coumarins and quinolinones has been developed.

A novel and green route has been developed for the electrochemical synthesis of spiro[4.5]trienones through radical‐initiated dearomative spirocyclization of alkynes with diselenides. This metal‐free and oxidant‐free electrosynthesis reaction was performed in an undivided cell under mild conditions. A variety of selenation spiro[4.5]trienones products were prepared in moderate‐to‐good yields, showing a broad scope and functional group tolerance. Moreover, the developed continuous‐flow system combined with electrosynthesis possesses the potential to achieve scaled‐up reactions, overcoming the low efficiency of conventional electrochemical scaled‐up reactions.

An efficient and green electrochemical continuous flow approach has been developed for the synthesis of 4-(sulfonylmethyl)isoquinoline-1,3(2H,4H)-diones through sulfonylation of alkenes with sulfonylhydrazides. The reaction proceeds in a flow electrolytic cell...

A novel and efficient approach to introduce fluorine-containing groups into N-heterocycles was reported.

A green and efficient approach for the synthesis of selenium-substituted iminoisobenzofuran using 2-vinylbenzamides and diselenides in a continuous electrochemical microreactor has been developed. This strategy enabled the preparation of a...
