Li+（3当量）被用作组装中心以从两个线性配位片段产生双链螺旋复合物，每个线性配位片段含有三个1，10-菲咯啉单元并且在其末端具有末端烯烃;在螺旋前体上的铼催化的闭环复分解以30%的产率产生4-交叉[2]-索烃，使得该过程合理地制备。
Li+ (3 equiv,) is used as an assembling centre to generate a double-stranded helical complex from two linear coordinating fragments, each containing three 1,10-phenanthroline units and bearing terminal olefins at their ends; ruthenium-catalyzed ring-closing metathesis on the helical precursor leads to a 4-crossing [2]-catenane in 30% yield, making the procedure reasonably preparative.
