Synthesis of catenane structures via ring-closing metathesis

This study presents a detailed description of a synthetic strategy to obtain catenane architectures through ring-closing metathesis. The approach is based on phenanthroline-based ligands containing terminal olefinic units that were designed to coordinate in a tetrahedral arrangement around a copper atom. Treatment of the assembled copper complexes with ruthenium catalyst 1 resulted in [2]catenates in high yields of 88-92%. Demetalation produced the corresponding [2]catenand in nearly quantitative yields. Hydrogenation of the catenates with Crabtree's catalyst and subsequent demetalation yielded fully saturated catenands. The presently described procedure makes [2]catenanes very accessible since the synthetic route consists of six steps (Schemes 2 and 4) from commercially available 1,10-phenanthroline, the overall yield being 51%.

Templated synthesis of highly stable, electroactive, and dynamic metal-DNA branched junctions

(Figure Presented) Templated metalation of DNA junctions allows incorporation of a range of transition metals into DNA assemblies. The resulting highly stable metal-DNA junctions can be assembled into dynamic multinuclear structures, with metal centers as their corners and DNA single strands as their sides. Ready and reversible structural switching of these assemblies with external agents (see picture) allows for control of geometry and metal-metal distances.

High-yield synthesis of [2]catenanes by intramolecular ring-closing metathesis

Almost quantitative formation of interlocking rings results upon cyclization of threaded or intertwined complexes. The synthesis concept is based on the combination of three-dimensional template effects and ruthenium benzylidene catalyzed ring-closing met

A transition metal ion assembled catenane bearing linearly-arranged donor and acceptor porphyrins

A new bis(porphyrin) has been synthezised in which a catenane is used as a spacer between the two chromophores, the donor and acceptor porphyrins being located as pendant groups, arranged linearly on each side of the catenane core.
