Used as a highly efficient catalyst in olefin metathesis reactions, particularly in ring-closing metathesis (RCM), cross metathesis (CM), and ring-opening metathesis polymerization (ROMP). It exhibits excellent activity and stability, even in the presence of functional groups and steric hindrance. Commonly applied in the synthesis of complex organic molecules, including pharmaceuticals, natural products, and advanced materials. Its robust performance under ambient conditions and compatibility with various substrates make it a preferred choice in both academic research and industrial processes.
