Abstract

An electrochemical deoxygenative sulfenylation strategy has been developed, employing odorless sodium sulfinates as the sulfenylation reagents. This method has been successfully applied to the synthesis of aminopyrazole thioether derivatives with moderate to good yields, which exhibits broad functional group tolerance and is readily scalable.
