Applicazioni


  • 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).
