Bis(dibenzylideneacetone)palladium(0)
Bis(dibenzylideneacetone)palladium(0), CAS 32005-36-0, is an organopalladium complex with the formula (C6H5CH=CHCOCH=CHC6H5)2Pd and a molar mass of 575.00 g/mol. Commonly abbreviated Pd(dba)2, it is a stabilised source of zero-valent palladium widely used in homogeneous catalysis. The labile dibenzylideneacetone ligands are readily displaced by phosphines and other donors, making it a versatile precatalyst for palladium-mediated coupling and synthesis.

Source of palladium(0)
Serves as a convenient, stabilised Pd(0) precursor in which the dibenzylideneacetone ligands are readily exchanged for stronger donor ligands. This makes it a practical starting point for generating active homogeneous palladium catalysts in situ.
Precatalyst for cross-coupling chemistry
Combined with phosphine or other supporting ligands, it is used to access catalytically active palladium species for carbon-carbon and carbon-heteroatom bond-forming reactions in fine-chemical and pharmaceutical synthesis.
Aerobic oxidation of alcohols
Employed with cyclic thiourea ligands in the efficient aerobic oxidation of alcohols to aldehydes and ketones. This illustrates its utility in selective oxidation under homogeneous palladium catalysis.
Research and method development
Used in academic and industrial laboratories for catalyst screening, ligand studies and reaction development where a well-defined zero-valent palladium source is required.
