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.
In enzymology, an acetylacetone-cleaving enzyme (EC 1.13.11.50) is an enzyme that catalyzes the chemical reaction. pentane-2,4-dione + O 2 acetate + 2-oxopropanal. Thus, the two substrates of this enzyme are pentane-2,4-dione and O 2, whereas its two products are acetate and 2-oxopropanal.
In the US, dimethyl carbonate was exempted under the definition of volatile organic compounds (VOCs) by the U.S. EPA in 2009. [9] Due to its classification as VOC exempt, dimethyl carbonate has grown in popularity and applications as a replacement for methyl ethyl ketone (MEK) and other solvents.
Sodium acetylacetonate is an organic compound with the nominal formula Na[CH(C(O)CH 3) 2]. This white, water-soluble solid is the conjugate base of acetylacetone . [ 1 ]
Scandium acetylacetonate is the coordination complex with the formula Sc(C 5 H 7 O 2) 3 where [C 5 H 7 O 2] − refers to acetylacetonate. It is a volatile white solid that is soluble in benzene. The complex features Sc(III) with octahedral molecular geometry. [1] It was first prepared by treating scandium nitrate with acetylacetone in the ...
Lanthanum acetylacetonate refers to the coordination complex with the formula La(C 5 H 7 O 2) 3. This anhydrous acetylacetonate complex has not been characterized well, but the dihydrate La(C 5 H 7 O 2) 3 (H 2 O) 2 has been characterized by X-ray crystallography. [2] [3] Upon heating under vacuum, the dihydrate converts to the oxo-cluster La 4 ...
Vanadyl acetylacetonate is the chemical compound with the formula VO(acac) 2, where acac – is the conjugate base of acetylacetone. It is a blue-green solid that dissolves in polar organic solvents. The coordination complex consists of the vanadyl group, VO 2+, bound to two acac – ligands via the two oxygen atoms on each.
Dysprosium acetylacetonate can be prepared by reacting dysprosium [2] or dysprosium hydride [3] with acetylacetone.Dy(acac) 3 ·EtOH·0.5Hacac (where Hacac represents acetylacetone) can be obtained by electrolysis of dysprosium cathode in ethanol solution of acetylacetone, which can be heated to generate Dy(acac) 3 through Dy(acac) 3 ·EtOH.
