Abstract

The template‐directed synthesis of the [2]catenane 1‐4 PF₆, in which a macrocyclic polyether is encircled by a tetracationic cyclophane, has been achieved in 58% yield. Of the four possible translational isomers, that shown on the right dominates in solution at low temperatures, according to ¹H NMR spectroscopy. This isomer is the only one observed in the solid state. (Figure Presented.)
