The Electrocatalysis Oxidant‐Free Construction of S–S Bond by Ce/Ti‐Bimetal MOF Catalyst

ABSTRACT Disulfide compounds, as the important industrial chemicals are widely used in rubber production, vulcanizing agents, agrochemicals and fabrication of advanced materials. However, the conventional synthesis methods of disulfide compounds are hitherto suffering from the limitations of low yield, toxic and unstable reagents, and a cumbersome preparation process. Thus, electrochemical coupling pathways as the emerging approach to synthesize the disulfide compounds have received myriad attention. Here, we provided an environmentally friendly and maneuverable protocol for the effective construction of S–S bond with the absence of oxygen and strong acid or alkaline environment based on Ce/Ti‐bimetal MOF catalyst. Significantly, Ce/Ti‐bimetal MOF exhibited excellent electrocatalytic performance for the construction of S–S bond. Based on the gentle reaction conditions, the production of disulfide compounds was up to 99%. Besides, further investigation proved that the yield of disulfide would not be significantly influenced by different substituents on the thiophenol.
