MSE PRO™ Pd 122, Dichlorobis(di-tert-butylphenyl phosphine)palladium(II), ≥98.0% Purity

MSE PRO™ Pd 122 is widely employed as a precatalyst in various cross-coupling reactions, such as Suzuki, Heck, and Sonogashira couplings, where it serves as a source of the catalytically active Pd(0) species. Featuring a square planar geometry with two chloride ligands and two bulky di-tert-butylphenylphosphine ligands, this complex exhibits exceptional air and moisture stability, ensuring convenient handling and storage. The steric protection provided by the phosphine ligands enhances the complex's robustness, making it an ideal choice for demanding synthetic transformations.

MSE Supplies offers various catalysts and ligands of coupling reaction. Please contact us for customization or bulk orders.
