Widely used as a ligand in transition metal catalysis, particularly in cross-coupling reactions such as Suzuki-Miyaura and Buchwald-Hartwig amination. Its bulky structure enhances catalyst stability and selectivity, making it effective in forming carbon-carbon and carbon-nitrogen bonds. Commonly applied in pharmaceutical synthesis for constructing complex organic molecules. Also utilized in materials science for developing advanced polymers and electronic materials. Its robust performance under harsh conditions makes it a preferred choice in industrial and academic research.
