Selective and specific dihydrogenation of benzene and other arenes has been observed in a low‐temperature helium plasma. A surface Birch reduction mechanism has been proposed in which benzene molecules adsorbed on the discharge surface capture low‐energy surface‐adsorbed electrons and subsequently undergo protonation (see picture). Gas‐phase oxidation processes accompany the reduction reaction.
