Hydrogenolysis over Metal Sulfide Catalysts

Over MoS3, alkyl and aryl thioethers are hydrogenolyzed to give hydrocarbons, via 

Diphenyl sulfide was converted to benzene over Re2S7 in ethanol at 300°C.173 However, thioethers appear to be stable at the temperatures of 155-245°C over Re2S7, since hydrogenation of allyl phenyl sulfide and thiophene over Re2S7 affords exclusively propyl phenyl sulfide at 150-160°C and thiolane at 230-260°C, respectively (eq. 13.98).173
