Organosulfur compounds are widely found in organisms, natural products, biologically active molecules and functional materials, which also represent indispensable precursors and intermediates in organic synthesis. Based on the importance of these compounds, the synthesis of organosulfur compounds is one of the intriguing research topic. The cross-coupling reaction of C—S bonds under electrochemical conditions can construct inter- or intramolecular C—S bonds selectively, which provides an efficient, green and economical synthetic pathway for constructing organosulfur compounds with diverse structures. The progress of electrochemical C—S bond formation in recent years is discussed, classified by different functional groups of organosulfur compounds. The reaction mechanism and applicability are summarised, and the challenges and opportunities in this field are also prospected and discussed.
