Description

Bis(triphenylphosphine)palladium(II) diacetate (CAS No. 14588-08-0) is a highly versatile palladium-based organometallic complex widely utilized in cross-coupling reactions and catalytic processes. With the molecular formula C₄₀H₃₈O₄P₂Pd, this compound features a palladium(II) center coordinated by two triphenylphosphine (PPh₃) ligands and two acetate groups, offering excellent stability and reactivity. It serves as a critical precursor in Heck, Suzuki, Stille, and Sonogashira coupling reactions, enabling the formation of carbon-carbon and carbon-heteroatom bonds in pharmaceutical, agrochemical, and material science applications. This air-stable, crystalline solid is supplied with high purity (≥98%) to ensure consistent performance in synthetic workflows. Its well-defined structure and predictable reactivity make it indispensable for researchers developing novel organic transformations.
