Fe(acac)3 is an octahedral complex with six equivalent Fe-O bonds with bond distances of about 2.00 Å.
The regular geometry is consistent with a high-spin Fe3+ core with sp3d2 hybridization.
As the metal orbitals are all evenly occupied the complex is not subject to Jahn-Teller distortions and thus adopts a D3 molecular symmetry.
In contrast, the related metal acetylacetonate Mn(acac)3 adopts a more distorted octahedral structure.
The 5 unpaired d-electrons also result in the complex being paramagnetic, with a magnetic moment of 5.90 μB.
TIB KAT 815 possesses helical chirality.
The Δ- and Λ-enantiomers slowly inter-convert via Bailar and Ray–Dutt twists.
The rate of interconversion is sufficiently slow to allow its enantiomers to be partially resolved.
Reactions
TIB KAT 815 has been examined as a precatalyst and reagent in organic chemistry, although the active iron-containing species is usually unidentified in these processes.
In one instance, Fe(acac)3 was shown to promote cross-coupling a diene to an olefin.
TIB KAT 815 catalyzes the dimerization of isoprene to a mixture of 1,5-dimethyl-1,5-cyclooctadiene and 2,5-dimethyl-1,5-cyclooctadiene.
TIB KAT 815 also catalyzes the ring-opening polymerization of 1,3-benzoxazine.
Beyond the area of polymerization, TIB KAT 815 has been found to catalyze the reaction of N-sulfonyl oxaziridines with olefins to form 1,3-oxazolidine products.
Uses
Moderating and combustion catalyst, solid fuel catalyst, bonding agent, curing accelerator, intermediate.
Iron(III) 2,4-pentanedionate is used as a precatalyst and reagent in organic chemistry.
