General description

Copper(II) acetylacetonate is an organometallic coordination compound widely used as a catalyst for several organic reactions, including oxidation, cross-coupling, and polymerization reactions. It is also a precursor to fabricate metal organic frameworks(MOFs) and nanomaterials.

Application

Copper(II) acetylacetonate can be used as:
  • A precursor for atomic layer deposition of copper oxide for all-oxide photovoltaics.
  • A catalyst for the aziridination of styrene.
  • A catalyst for Huisgen-Click reaction to synthesize 1,2,3-triazoles.

Nearly monodisperse lanthanide-doped magnetite nanoparticles were obtained by thermally decomposing a mixture of Fe(acac)(3) and Ln(acac)(3) (acac = acetylacetonate; Ln = Sm, Eu, Gd) in the presence of passivating surfactants. Magnetic studies revealed room-temperature ferromagnetic behaviors of these doped nanoparticles
