Reaktionsschritte
Cobalt(II) acetylacetonate in essentially anhydrous form was first produced from commercially available cobalt(II) acetylacetonate hydrate. A suspension of the cobalt(II) acetylacetonate hydrate (about 10 g) and toluene (200 mL) was heated to reflux under nitrogen atmosphere with agitation for 24 hours. Water was accordingly refluxed into a Dean-Stark trap. The resulting mixture was then filtered in a nitrogen atmosphere and dried in vacuo for a period of between 1 and 2 hours to give the anhydrous cobalt(II) acetylacetonate.
