Gallium acetylacetonate, also referred to as Ga(acac) 3, is a coordination complex with formula Ga(C 5 H 7 O 2) 3. This gallium complex with three acetylacetonate ...
The synthesis of Co(acac) 3 involves the use of an oxidant since the cobalt precursors are divalent: 2 CoCO 3 + 6 Hacac + H 2 O 2 → 2 Co(acac) 3 + 4 H 2 O + 2 CO 2. The complex "Co(acac) 2", like the nickel complex with analogous stoichiometry, is typically isolated with two additional ligands, i.e. octahedral Co(acac) 2 L 2.
acetic acid synthesis; Eastman acetic anhydride process; Ethylene-carbon monoxide copolymerization; A reaction involving metal acyl complexes of occasional value in organic synthesis is the Tsuji–Wilkinson decarbonylation reaction of aldehydes.
A ball-and-stick model of VO(acac) 2. Sodium acetylacetonate, Na(acac), is the precursor to many acetylacetonate complexes. A general method of synthesis is to treat a metal salt with acetylacetone in the presence of a base: [12] MB z + z Hacac ⇌ M(acac) z + z BH. Both oxygen atoms bind to the metal to form a six-membered chelate ring.
Thus, much effort has been aimed at the synthesis of new molecular precursors. A productive overview is provided by several exceptional reviews covering fields of MOCVD such as, for instance, epitaxial growth of semiconductor compounds, [ 2 ] [ 3 ] [ 4 ] and low temperature deposition of metals.

Selenium plays important roles in hormone function, a healthy metabolism, DNA synthesis and protection from oxidative damage and infection, notes the U.S. National Institutes of Health (NIH ...
Gallium is moderately water-soluble and decomposes to gallium oxide when heated to around 70 °C. [2] Gallium acetate, like other acetate compounds, is a good precursor to ultra-pure compounds, catalysts and nanoscale materials. [2] Gallium acetate is being considered as a substitute in de-icing compounds like calcium chloride and magnesium ...
