Widely used as a highly active palladium-based catalyst in cross-coupling reactions, particularly in Buchwald–Hartwig amination and Suzuki–Miyaura coupling. Its sterically hindered phosphine ligand enhances catalyst stability and promotes efficient C–N and C–C bond formation under mild conditions. Commonly applied in the synthesis of pharmaceuticals, agrochemicals, and functional materials where high selectivity and yield are required. The presence of the dichloromethane adduct helps stabilize the complex during storage and handling, maintaining catalytic activity over time. Effective even at low catalyst loadings, making it suitable for large-scale industrial applications.
