Catalysts are important factors affecting the hydrogenation of nitrile compounds. The type and preparation method of catalysts plays a crucial role in the selectivity of the reaction. Therefore, we tested the effects of different catalysts on the catalytic hydrogenation of BN in a batch reactor, evaluated the six selected catalysts, and the yields of the target products are summarized in Fig. . Obviously, the effects of the two commercially available catalysts are far from satisfactory. For the Pd/C catalyst, the substrate conversion can be fully carried out, but the selectivity for benzylamine is only 43.49%, and the remaining products include dibenzylamine, toluene and a small amount of benzyl alcohol. For the Ru/C catalyst, we detected a large amount of residual BN in the reaction solution, and the conversion rate was only 45.32%. The target product showed a high selectivity of 99.25%, and the rest was N-benzylbutylamine. The amination ideas reported in the past literature were all completed under the catalysts of Raney Ni , but considering that Raney Ni itself is extremely prone to spontaneous combustion when in contact with air , it is highly dangerous and is not used in this experiment. Then, we replaced Raney nickel with the developed graphene-encapsulated Ni-based catalyst to hydrogenate BN. Unlike the effect of the above-mentioned precious metal catalysts, we could achieve 80.81% conversion rate and 91.94% selectivity on the Ni@C catalyst, indicating the feasibility of transition metal elements in the reaction of hydrogenation of nitrile to amine.
