Bis(triphenylphosphine)palladium(II) acetate(CAT: M051674) is a well-defined palladium(II) complex widely used as a pre-catalyst in cross-coupling reactions, including Suzuki–Miyaura, Heck, and Stille reactions. Featuring two triphenylphosphine ligands and an acetate counterion, it offers high reactivity and solubility in organic solvents, making it ideal for homogeneous catalysis. This air-stable, easily handled complex enables efficient formation of C–C and C–heteroatom bonds under mild conditions, supporting its extensive use in pharmaceutical synthesis, fine chemicals, and materials science. Its ligand environment promotes predictable reactivity and selectivity, making it a go-to choice for both academic and industrial-scale catalytic transformations.
