Development of a Cobalt Catalyst from ZIF‐67 and Application in the Hydrogenation of N‐Heteroarenes

Le résumé fourni par la source

Abstract Hydrogenation of N‐heteroarenes to saturated N‐heterocycles is an important reaction in organic synthesis. Hydrogen is a green reducing reagent and has been widely applied in industrial production. The development of an appropriate catalyst to realize hydrogenation at low pressure and temperature is desired. In this study, we developed a cobalt‐based catalyst derived from ZIF‐67 that exhibits high activity for N‐heteroarene hydrogenation under 5–20 bar hydrogen, which is a relatively low pressure as compared to reported catalytic systems. This nano‐cobalt catalyst shows broad substrate scope and can be reused without obvious activity loss.
