Tetrakis(triphenylphosphine)palladium(0), [Pd(PPh₃)₄],(CAT: R040301) is a yellow, air-sensitive coordination complex widely used as a homogeneous catalyst in organic synthesis. Featuring a palladium(0) center coordinated by four triphenylphosphine ligands, it offers exceptional stability in inert conditions and high reactivity in cross-coupling reactions. It is a key catalyst for Suzuki, Heck, Stille, and Sonogashira couplings, enabling the formation of C–C and C–X bonds with excellent selectivity. Its solubility in organic solvents and compatibility with diverse substrates make it a versatile choice in pharmaceuticals, fine chemicals, and materials research. The compound must be stored under inert atmosphere to preserve its catalytic activity.
