Used as a ligand in homogeneous catalysis, particularly in palladium-catalyzed cross-coupling reactions such as Suzuki, Heck, and Negishi couplings. Its bulky alkyl substituents provide steric hindrance that enhances catalyst stability and selectivity. The 10 wt% solution in hexanes facilitates easy handling and precise dosing in air-sensitive reactions, making it suitable for use in organic synthesis of pharmaceuticals, agrochemicals, and fine chemicals. Commonly employed in research and industrial settings where controlled ligand loading is required for optimal catalytic performance.
