Ring-Closing Metathesis 2 Rotaxane

Abstract Alkene metathesis has become a synthetic method that has strongly modified approaches in the building of complex molecules. The review will concentrate on the recent applications of ring-closing metathesis (RCM) and crossmetathesis (CM) reactions for the design of useful molecules and architectures new functional macrocycles (RCM) and multifunctional linear alkenes (CM), but also cyclic ligands, rotaxanes, catenanes, and supramolecular systems.
