A [2]catenane has been constructed using an octahedral complex of the Ru(diimine)( 2+)(3) family as a scaffold. Two diimine chelates have been incorporated in a ring prior to the ruthenium(II) complexation reaction. The macrocyclic complex thus obtained has been subsequently threaded by a long linear fragment containing the third chelate. The rutheniuml(II)-complexed catenane, cyclized by ring-closing
[2] 链已使用 Ru(diimine)( 2+)(3) 家族的八面体复合物作为支架构建。在钌 (II) 络合反应之前,已将两种二亚胺螯合物结合到一个环中。如此获得的大环复合物随后被包含第三螯合物的长线性片段穿过。通过闭环复分解环化的钌 (II) 络合的链烯是围绕八面体三螯合物构建的互锁环系统的第一个例子。
