Used as a highly efficient catalyst in olefin metathesis reactions, particularly in the synthesis of complex organic molecules such as pharmaceuticals and fine chemicals. Its robust structure allows for excellent activity and selectivity, even with sterically hindered substrates. Commonly employed in ring-closing metathesis (RCM) and cross-metathesis (CM) transformations, it offers good functional group tolerance and stability under various reaction conditions. This catalyst is especially valuable in industrial and academic research settings where high yields and reproducibility are required.
