This invention relates generally to olefin metathesis, more particularly, to tri- or tetra-substituted imidazoliniυm salts which are precursors to N-heterocyclic carbene (NHC) ligands with tri- or tetra-substituted irnidazolinium rings, organometallic ruthenium complexes comprising gem di-substituted imidazoiinium NHC ligands, organometallic ruthenium complexes comprising tri- or tetra-substituted imidazoiinium NHC ligands, and to olefin metathesis methods using them. The catalysts and methods of the invention have utility in the fields of catalysis, organic synthesis, and industrial chemistry.
