Widely used as a precatalyst in homogeneous catalysis, particularly in olefin metathesis reactions. It shows high activity in ring-closing metathesis (RCM) and ring-opening metathesis polymerization (ROMP), enabling efficient synthesis of cyclic compounds and functional polymers. Its stability and reactivity make it suitable for use in pharmaceutical manufacturing and fine chemical synthesis. Also employed in C–H activation reactions, where it facilitates direct functionalization of hydrocarbons, offering streamlined routes in complex molecule assembly. The dimeric structure enhances catalyst longevity and turnover under various reaction conditions.
