Pd(PPh3)4

Pd(PPh₃)₄, known as tetrakis(triphenylphosphine)palladium(0), is a chemical compound used as a catalyst in organic chemistry. It contains a palladium metal atom at its center, bonded to four triphenylphosphine ligands. This complex facilitates chemical reactions—particularly cross-coupling reactions—by helping other molecules connect or break apart more efficiently. Its structure allows it to stay stable while actively promoting reactions, making it a valuable tool for constructing complex organic compounds, including pharmaceuticals and materials.
