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.[1] [2]

Application

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