The catalytic hydrogenation of N-heteroarenes showcases wide and important applications in the fields of synthetic chemistry, drug discovery, materials science, and hydrogen storage. However, it remains a long-standing scientific and technological challenge in breaking the aromaticity of substrates and overcoming catalyst poisoning by either substrates or hydrogenated products. Although different homogeneous systems mainly based on precious metal catalysts have been developed, harsh conditions with extra additives are always required.
