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 with substrates containing sensitive functional groups, making it valuable in the synthesis of complex organic molecules, including pharmaceuticals and natural products. Its stability under ambient conditions and tolerance to air and moisture enhance its utility in industrial and laboratory-scale applications. Commonly employed in the formation of cyclic structures such as lactams, lactones, and macrocycles.
