title: Synthesis of a [2]catenane around a Ru(diimine)3(2+) scaffold by ring-closing metathesis of olefins.
abstract: [reaction: see text] The synthesis of a ruthenium[2]catenane is described. One ring includes two 1,10-phenanthroline moieties, the other a bipyridinic unit. The interlocking ring system was formed by using a double ring closing metathesis reaction. Under irradiation, a rapid and selective decoordination of the bipyridinic fragment was observed, leading to a new catenane in which the metal is only coordinated to the bis-phenanthroline moiety.
