Tris(dibenzylideneacetone)dipalladium(0)-chloroform adduct（Cat No.:R062597）, often abbreviated as Pd₂(dba)₃·CHCl₃, is a coordination complex consisting of two palladium(0) atoms stabilized by three dibenzylideneacetone (dba) ligands, with chloroform acting as a solvate. This dark purple crystalline compound is widely used as a precatalyst in cross-coupling reactions such as Suzuki, Heck, and Stille couplings. The dba ligands are weakly bound, allowing facile ligand exchange during catalysis. Its solubility in organic solvents and thermal stability make it a preferred source of palladium(0) in homogeneous catalysis for synthesizing pharmaceuticals and fine chemicals.
