The catalytic effect of explicit water molecules on the keto-enol tautomerism in a system of biological interest (enolpyruvate) has been investigated at the B3LYP/6-31++G** level by exploring the potential energy surface in the presence of 1 or 2 water molecules

Journal of molecular modeling, 18(6), 2409-2422 (2011-10-13)
Theoretical and spectroscopic studies of a series of monomeric and dimeric complexes formed through the modification of a zirconium butoxide precursor with acetylacetone and subsequent hydrolysis and/or condensation have been performed by applying DFT/B3LYP/6-31++G(d) and highly accurate RI-ADC(2) methods as

Acetylacetone dioxygenase (Dke1) is a bacterial enzyme that catalyzes the dioxygen-dependent degradation of β-dicarbonyl compounds. The Dke1 active site contains a nonheme monoiron(II) center facially ligated by three histidine residues (the 3His triad); coordination of the substrate in a bidentate
Sensitive fluorescence detection of etimicin based on derivatives of formaldehyde and acetylacetone.
Yafeng Zhuang et al.
Journal of fluorescence, 23(1), 1-5 (2012-08-25)
A novel fluorescence method for the determination of etimicin is described. Etimicin reacts with acetylacetone and formaldehyde in pH 4.0 Britton-Robinson (B.R.) buffer solution to from a fluorescent substance [I]. Emission spectra of [I] and the reagent blank were overlapped

Herein we report the synthesis and photophysical study of tris-heteroleptic complexes of the general formula IrLL'(acac), where L and L' are two differently substituted 2-phenylpyridines (ppyH) and acacH is 2,4-pentanedione, using a combinatorial approach that could be employed for many
