The Fe-catalyzed hydrogenolysis of <I>trans</I>-stilbene was carried out in aromatic hydrocarbon solvents at 380 °C. α-Fe and pyrrhotite catalyze bimolecular hydrogen transfer from hydroaromatic hydrocarbons to <I>trans</I>-stilbene and hydroaromatic hydrocarbon-mediated hydrogenolysis of <I>trans</I>-stilbene by molecular hydrogen at 380 °C. This catalyzed hydrogen transfer proceeds by radical mechanism. The product distribution is affected by the catalyst species. Pyrrhotite catalyzes the hydrogenation of <I>trans</I>-stilbene more effectively than α-Fe. Both the iron catalysts are inactive toward the cleavage of carbon to carbon single bond in bibenzyl.
