Widely used in ring-closing metathesis (RCM) reactions to form medium and large rings, especially in complex molecule synthesis. Effective in cross-metathesis (CM) for constructing C=C bonds with high selectivity. Applied in pharmaceutical and natural product synthesis due to its stability and functional group tolerance. Operates under mild conditions, often at room temperature, and can be used in air-sensitive reactions with proper handling. Shows good recyclability in some solvent systems, making it favorable for industrial-scale applications where catalyst efficiency is critical.
