Article Synopsis

The paper critically presents various routes for immobilising ruthenium alkylidene complexes through their ligands. This part (Part I) describes immobilisation via coordinating/actor ligands (phosphane/alkylidene), and established ancillary ligands such as N-heterocyclic carbenes. Other ligands commonly encountered in immobilisation protocols, such as Schiff bases, arenes, anionic ligands and specifically tagged (ionic liquid tag, fluoro tag) substituents will be the topic of Part II. Selected applications of some of these ruthenium complexes in olefin metathesis reactions are highlighted where they are particularly advantageous.

Note: An actor ligand is endowed with a functionality enabling it to introduce a chemical transformation at its site of action. An ancillary ligand provides essential support to the actor ligand while the chemical transformation is performed. A spectator ligand is present in the metal coordination sphere, yet does not directly affect the capacity of the actor ligand to induce a chemical transformation.
