Widely used as a highly efficient catalyst in olefin metathesis reactions, particularly in ring-closing metathesis (RCM) and cross-metathesis (CM) processes. It demonstrates excellent activity and stability, even in the presence of functional groups and steric hindrance, making it suitable for complex organic synthesis. Commonly applied in pharmaceutical manufacturing and polymer chemistry for constructing carbon-carbon double bonds with high selectivity. Its robustness allows for use under mild conditions and often with low catalyst loading, improving cost efficiency and reducing metal residues in final products.
