Used as a highly efficient catalyst in cross-coupling reactions, particularly in Suzuki and Heck reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and fine chemical synthesis. Its phosphine ligands enhance stability and reactivity, making it suitable for reactions under mild conditions with high selectivity. Commonly applied in the preparation of complex organic molecules, including active pharmaceutical ingredients (APIs), where reliable catalytic performance is required. Also utilized in research laboratories for developing new synthetic methodologies due to its air-stable and user-friendly properties.
