Bis(acetylacetonato)cobalt

Description

Bis (acetylacetonato) cobalt (also known as Cobalt (II) acetylacetonate) is used as an important catalyst for organic reactions. It can also be used as paint dryer¹. The cobalt (II) acetylacetonate complex immobilized on aminosilane-modified SBA-15 can act as an efficient catalyst for epoxidation of trans-stilbene with molecular oxygen². Cobalt (II) Acetylacetonate is a cobalt source that is soluble in organic solvents as an organometallic compound (also known as metalorganic, organo-inorganic and metallo-organic compounds). The high purity acetylacetonate anion complexes by bonding each oxygen atom to the metallic cation to form a chelate ring; because of this property, acetylacetonates are commonly used in various catalysts and catalytic reagents for organic synthesis, including the fabrication of various shapes of carbon nanostructures (as demonstrated by a 2013 experiment by researchers at the Leibniz Institute for Solid State and Materials Research Dresden) via the use of chemical vapor deposition (CVD) and laser evaporation techniques³.
