The catalytic activity depends on the central metal ion in the cluster, and the order activity is ytterbium < europium < samarium ≈ neodymium. The catalysts show a wide range of scope in their activity towards amines including aliphatic amines and secondary cyclic amines such as pyrrolidine and piperidine.展开更多
