Equilibrium studies of thiophene exchange in (η-thiophene)Ru(η-C5H5)+: A model for thiophene adsorption on hydrodesulfurization catalysts

Equilibrium constants (K′) for the displacement of the π- (i.e., η5-) thiophene (T) ligand in CpRu(T)+ by methyl-substituted thiophenes (Th′), CpRu(T)+ + Th′ ? CpRu(Th′)+ + T, increase as the number of methyl groups in Th′ increases: T (1) 2T (35) 2T (50) 3T(200) 3T (300) 4T (1300). The K′ values increase by a factor of approximately 6 for each methyl in the thiophene (Th′). That thiophenes also adsorb to a Co-Mo/Al2O3 hydrodesulfurization (HDS) catalyst more strongly as the number of methyl groups in the thiophene increases suggests that they are also π-bonded to the catalyst surface. The results suggest that trends in rates of deuterium exchange and hydrodesulfurization on HDS catalysts for a series of methyl-substituted thiophenes are determined by their relative strengths of adsorption to the catalyst surface.
