Used as a highly reactive catalyst precursor in organometallic and polymerization reactions, particularly in the synthesis of advanced polyolefins and stereoregular polymers. Its bulky ligand structure enhances steric control, making it effective in catalyzing olefin insertion and C–H activation processes. Also employed in vapor deposition processes for creating yttrium-containing thin films in electronic and optical materials. The compound’s strong Lewis acidity supports its use in promoting challenging bond-forming reactions in research laboratories focused on synthetic inorganic and organometallic chemistry.
