Bis[1,2-bis(diphenylphosphino)ethane]palladium(0)
Bis[1,2-bis(diphenylphosphino)ethane]palladium(0) (CAS 31277-98-2), formula [(C6H5)2PCH2CH2P(C6H5)2]2Pd and molar mass 903.25 g/mol, is a homogeneous palladium(0) complex bearing two chelating dppe ligands. The bidentate phosphines stabilise the zero-valent metal centre, making it a defined precatalyst and Pd(0) source for cross-coupling and related synthetic chemistry. Tech Serve Solutions supplies it as a research and laboratory reagent to organic chemists and process development teams worldwide.

Palladium(0) source for cross-coupling
Serves as a defined, ligated source of zero-valent palladium for carbon-carbon and carbon-heteroatom bond formation. The chelating dppe ligands provide a stable, well-characterised entry point into homogeneous Pd catalysis.
Homogeneous catalysis research
Used in academic and industrial laboratories investigating palladium-catalysed reaction mechanisms, ligand effects and catalyst speciation, where a discrete bis(diphosphine) complex is preferred over in-situ generated systems.
Organometallic and coordination chemistry
Acts as a model bis(chelate) Pd(0) complex for studies of oxidative addition, ligand substitution and the coordination behaviour of bidentate phosphines at palladium.
Pharmaceutical and fine-chemical synthesis
Employed as a catalyst or catalyst precursor in the construction of complex molecules and intermediates, supporting route development and methodology work in fine-chemical and pharmaceutical research.
