US 9,427,731 B2 · Supported olefin metathesis catalysts

Abstract

Supported olefin metathesis catalysts are disclosed, and more particularly, a supported catalyst complex comprising a catalyst composed of a Group 8 transition metal complex comprising a labile ligand and a non-labile ligand and a support, wherein the metal complex and the support are linked together by one or more linkers, in which one of the linkers connects the labile ligand of the complex to the support and the same or a different linker connects the non-labile ligand of the complex to the support. A method for preparing a supported catalyst complex is further disclosed. The invention further relates to the use of the supported olefin metathesis catalyst in performing metathesis reactions. The invention has utility in the fields of catalysis, organic synthesis, polymer chemistry, and industrial and fine chemicals chemistry.
