Widely used as a ligand in transition metal catalysis, particularly in cross-coupling reactions like Suzuki-Miyaura and Buchwald-Hartwig couplings. Its bulky structure enhances steric hindrance, improving selectivity and efficiency in forming carbon-carbon and carbon-nitrogen bonds. Commonly applied in pharmaceutical synthesis to create complex organic molecules. Also utilized in materials science for developing advanced polymers and organic electronic materials. Its stability and reactivity make it valuable in industrial-scale chemical processes.
