A multipoint mechanism is proposed according to which the thiophenic molecule is chemisorbed with the C/sub 1/-C/sub 2/ bond coordinated at an anion vacancy and the adjacent sulfur is interacting with a surface sulfur. The reaction paths possible for this surface species can account for available experimental data on the high yield and initial formation rate of biphenyl from dibenzothiophene, the small steric effect of substituents, preferred positions of hydrogen-deuterium exchange of thiophene, and the amount of butadiene produced in the desulfurization of tetrahydrothiophene.
