Summary This chapter briefly summarizes the different approaches to supported metathesis catalysts. In doing that, both organic and inorganic supports are addressed. In principle, Schrock catalysts can be immobilized via the alkylidene ligand, via substitution of one or two alkoxides or via the arylimido ligand. Currently, different types of ruthenium alkylidenes are available, usually referred to as first-, second- and third-generation Grubbs and first- and second-generation Grubbs–Hoveyda catalysts. Finally, an entirely novel approach to catalyst immobilization, that is, the use of ionic metathesis catalysts working in a supported ionic liquid phase (SILP) and the advantages of such an approach over existing ones is addressed. Taking advantage of the high stability and pronounced affinity of second-generation Grubbs–Hoveyda catalysts to silica, a number of groups simply physisorbed this catalyst to silica, MCM-41, and SBA-15.
