Abstract
Catalyst materials for olefin metathesis reactions. The catalyst materials comprise a ruthenium phosphinimine complex. The ruthenium phosphinimine may be synthesized without bound N-heterocyclic carbene (NHC) or phosphine ligands, thereby providing significant advantageous in conversion, selectivity, and stability compared to existing ruthenium-based catalysts.
Claims36
