title: A catenane consisting of a large ring threaded through both cyclic units of a handcuff-like compound.
abstract: The template effect of copper(I) allowed the preparation of a new catenane constructed around a bis-macrocyclic unit; a double ring-closing metathesis reaction afforded the central ring which is threaded through both rings of the bis-macrocycle.
