Mechanism of the hydrogenolysis of thiophene on bimetallic sulfide catalysts

The structure of the sulfide bimetallic species (SBMS), which is the active component of hydrodesulphurisation catalysts, is examined. The main principles of the hydrogenolysis of thiophene on well-characterised sulfide catalysts have been analysed. A synchronous mechanism for the reaction of thiophene with hydrogen in the coordination sphere is considered and substantiated. The bibliography includes 143 references.
