Abstract:
The invention pertains to the use of Group 8 transition metal alkylidene complexes as catalysts for olefin cross-metathesis reactions. In particular, ruthenium and osmium alkylidene complexes substituted with an N-heterocyclic carbene ligand and at least one electron donor ligand in the form of a heterocyclic group are used to catalyze cross-metathesis reactions to provide a olefin products that are directly substituted with an electron-withdrawing group.
