中文摘要：
Na8Ln (OtBu ) 的 Heterobimetallic 簇 10 (哦)( 行 = 镱，铕，钐和钕) 被发现是为有在温和条件下面的胺的醛的 amidation 的有用催化剂。催化活动在簇取决于中央金属离子，并且顺序活动是镱 < 铕 < 钐钕。催化剂包括象 pyrrolidine 和哌啶那样的脂肪族的胺和第二等的周期的胺向胺在他们的活动显示出大量范围。
英文摘要：
Heterobimetallic clusters of NasLn（OtBu）10（OH） （Ln = ytterbium, europium, samarium and neodymium） are found to be useful catalysts for amidation of aldehydes with amines under mild conditions. 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.
