Tris(dibenzylideneacetone)dipalladium(0)) or (dba)3Pd2. is an organometallic catalyst based on palladium and dibenzylideneacetone used in organic chemistry.


It is prepared by adding hot sodium acetate to a hot methanol solution of dibenzylideneacetone and sodium hexachloro palladate (IV) [1]

Examples of reactions using this reagent are the Negishi coupling, Carroll rearrangement and Trost asymmetric allylic alkylation. Another zerovalent palladium catalyst is tetrakis(triphenylphosphine)palladium(0)
