Cover Picture: Gold(I)-Template Catenane and Rotaxane Synthesis (Angew. Chem. Int. Ed. 37/2008)
There's gold in them thar rings according to David Leigh and co-workers in their Communication on page 6999 ff. The last of the simple metal coordination geometries—linear—has joined the family of metal–ligand arrangements that have been used to template the formation of the mechanical bond. Catenanes and rotaxanes can be easily synthesized using this versatile gold(I)-directed assembly, suggesting that there may be plenty more treasure uncovered using this interlocking template system.
