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

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 under low pressure and temperature is desired. In this study, we developed a cobalt‐based catalyst derived from ZIF‐67, and it exhibits high activity for N‐heteroarene hydrogenation under 5‐20 bar hydrogen, which is relatively low compared to reported catalytic systems. This nano‐cobalt catalyst shows a broad substrate scope and can be reused without obvious activity loss.
