controlled cross‐couplingreactions. The high‐yielding synthesis of ethynylene‐linked rigid tetrameric cages via one‐step alkyne metathesis from readily accessible triyne precursors is presented. The tetrameric cage contains two macrocyclic panels and exhibits D2h symmetry. The assembly of such a COP is a thermodynamically controlled process, which involves the initial formation of macrocycles as key intermediates
具有乙炔基连接基的形状持久性共价有机多面体(COP)通常是通过动力学控制的交叉偶联反应制备的。本文介绍了乙炔连接的刚性四聚体笼的高产合成,它是由易得的三炔前体通过一步炔烃复分解制得的。四聚体笼包含两个大环板,并表现出D 2 h对称性。这种COP的组装是热力学控制的过程,其涉及大环的初步形成作为关键中间体,然后将两个大环与乙炔键连接。内腔大,笼对C 70的结合选择性高(K = 3.9×10 3 L mol-1)在C 60上(无明显结合)。
