General description

Cobalt(II)acetylacetonate (Co(acac)2) is a coordination compound in which acentral cobalt atom is coordinated to two acetylacetonate ligands, which act asbidentate ligands. It is used in various applications such as organicsynthesis, coordination chemistry, and as a catalyst in several chemicalreactions. Additionally, Co(acac)2 is used as a precursor in processes such aschemical vapor deposition (CVD) and laser evaporation techniques for thefabrication of thin films. It also plays a crucial role in the production ofcobalt oxide thin films, which find applications in electronics, catalysis, andother fields requiring thin film coatings.

Application


  • Cobalt (II)-Catalyzed Isocyanide Insertion Reaction with Amines: Details a synthetic method for forming ureas and azaheterocycles catalyzed by Cobalt(II) acetylacetonate, applicable in pharmaceutical synthesis (Zhu et al., 2014).

  • Cobalt‐Catalyzed C−H Functionalizations by Imidate Assistance: Describes a method using Cobalt(II) acetylacetonate for C-H functionalization, important for organic synthesis and material chemistry (Mei & Ackermann, 2016).

  • Cobalt (II) acetylacetonate covalently anchored onto magnetic mesoporous silica nanospheres: Focuses on its use as a catalyst for epoxidation of olefins, relevant for catalysis research (Li et al., 2015).

Cobalt(II) acetylacetonate can be used:
  • A precursor in the solvothermal synthesis of Co3O4 nanoparticles. These nanoparticles exhibit high electrochemical performance and are used as a potential supercapacitor material due to their excellent capacitance and cycling stability.
  • A precursor in the preparation of Co3O4 nanoparticles via hydrothermal method. The resulting Co3O4 nanoparticles exhibit a highly-uniform mesoporous structure and tunable sizes, making them promising for CO sensing applications.
  • A precursor for the growth of cobalt oxide thin films using Metal-Organic Chemical Vapor Deposition (MOCVD).
