Bis(3,5,3′,5′-dimethoxydibenzylideneacetone)palladium(0)
Bis(3,5,3′,5′-dimethoxydibenzylideneacetone)palladium(0), CAS 811862-77-8, is a homogeneous palladium(0) complex with the empirical formula C42H44O10Pd and a molecular weight of 815.21. Abbreviated Pd(dmdba)2, it bears electron-rich dimethoxy-substituted dibenzylideneacetone ligands and serves as a well-defined, labile source of zero-valent palladium for catalysis. Tech Serve Solutions supplies it as a research-grade reagent (assay 96%) for cross-coupling and related synthesis. It is offered for laboratory and manufacturing research use.

Palladium(0) source for catalysis
Pd(dmdba)2 acts as a labile, well-defined source of zero-valent palladium. Its weakly coordinating dibenzylideneacetone ligands are readily displaced by phosphines, N-heterocyclic carbenes and other ligands to generate active catalytic species in situ.
Cross-coupling reactions
As a dba-type Pd(0) complex it is used in homogeneous palladium-catalysed carbon–carbon and carbon–heteroatom bond formation, including couplings of the Suzuki, Heck, Negishi, Stille and Buchwald–Hartwig families when paired with a suitable ligand.
Catalyst and ligand-screening studies
The electron-rich dimethoxy-substituted dba ligands make this complex a useful precursor for methodology development and for screening ligand and base combinations in homogeneous palladium catalysis.
Fine-chemical and pharmaceutical intermediate synthesis
Defined Pd(0) precursors of this type support the construction of biaryl, amine and other motifs common to pharmaceutical intermediates and advanced fine chemicals at research and process-development scale.
