General description

Palladium(II) acetylacetonate (Pd(acac)2) is a metal-organic complex. Sublimation of Pd(acac)2 has been investigated by thermogravimetry and XRD. The temperature range for the sublimation of Pd(acac)2, without undergoing thermal decomposition, was determined to be 100-160°C in the presence of inert gas helium.


Application Guide for Palladium Catalyzed Cross-Coupling Reactions

Palladium(II) acetylacetonate (Pd(acac)2) was used in the following studies:
• Typical high-temperature organic solution phase protocol for the preparation of monodisperse CuPd alloy nanoparticles (NPs).
• Preparation of [(NHC)Pd(acac)L] (where L=Me, NHC = N-heterocyclic carbene) complexes. These complexes efficiently catalyze the Heck reaction of activated aryl bromides.
• As catalyst in the decarboxylative cross-coupling of arylcarboxylic acids with aryl halides.
