Palladium dibenzylidineacetone (dba) complexes, such as tris(dibenzylidineacetone)dipalladium(0) (Pd2dba3), are common sources of palladium in the synthesis of many different organometallic compounds. However, complications can arise when purifying the desired product from the released dba ligands. Past research has shown that when hydroxyl groups are placed in the para position of the benzene rings on the dibenzylideneacetone ligands, the solubilities of both the precursor and the dba ligands are changed, making the purification of the desired products more readily achieved. In this paper, we present the synthesis of a di(3-ethoxy-4-hydroxybenzylidene)acetone palladium(0) complex, as well as the use of this complex as a palladium source in the synthesis of a variety of catalytically useful palladium compounds.
