Tris(dibenzylideneacetone)dipalladium(0)

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)

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)
