摘要 Hydrogenation reactions of polycyclic arenes (PAs) were carried out in the presence of Ni and sulfur at 300 ℃ to examine the structural effect of PAs on their reactivities toward hydrogenation. Hydrogen was observed to be transferred preferentially to some fixed positions in PAs and different PAs displayed some difference in hydrogenation reactivity. The results can be interpreted on the hydrogen accepting ability of carbon atoms from different positions in PAs and the resonance stability of aryl radicals resulting from H atom addition as well as the adsorption strength of PAs on catalyst surface.
