Density functional theory was used to investigate the oxidative addition and subsequent carbonyl insertion and deinsertion steps of the reaction of methyl iodide to a rhodium(I) acetylacetonato complex of the formula [Rh(acac)(CO)(PPh(3))] (Hacac = acetylacetone). This process has been studied experimentally for many rhodium β-diketonato complexes, but, to the best of our knowledge, this is the...

Perfluoromalonyl difluoride reacts with TMS-CF3 (1:1) in the presence of KF to give the new diketone CF2(C(O)CF3)2. A large excess (5:1) of TMS-CF3 results in the presumed potassium dialkoxide [(CF3)2COK]2CF2 which yields the 1,3-ditertiarydiol [(CF3)2C(OH)]2CF2 on reaction with H2SO4.

The photochemistry of the chelated enol form of acetylacetone (AcAc) was investigated by UV excitation of the S(2) state at 266 nm in parahydrogen matrices, complemented by experiments in neon and normal hydrogen matrices. Infrared (IR) spectroscopy, combined with theoretical calculations, was used to identify the photoproducts. Isomerization towards various non-chelated forms (no intramolecula...

New Ru(ii)- and Os(ii)-polypyridyl complexes have been synthesized with pendant acetylacetone (acac) functionality for anchoring on nanoparticulate TiO2 surfaces with a goal of developing an alternate sensitizer that could be utilized for designing an efficient dye-sensitized solar cell (DSSC). Time-resolved transient absorption spectroscopic studies in the femtosecond time domain have been car...

The nature of the intramolecular hydrogen bond in the enol tautomer of 2,4-pentanedione has been investigated by high resolution proton and deuteron magnetic resonance spectroscopy. An unusually large deuterium isotope effect on the chemical shift of the bridge hydrogen has been observed. This unexpected result, together with the observation of a pronounced temperature dependence for both the p...

Excess formaldehyde (FA) provides a significant threat that causes irreversible damage to both the environment and human health, long-term FA emission from commercial leather products is problem. Therefore, help control content, we propose fluorescence-based method detect selectively using reaction-based probe FAP-1. Water-soluble FAP-1 was simply synthesized through two steps optical propertie...

The improvement in the efficiency of inverted perovskite solar cells (PSCs) is significantly limited by undesirable contact at NiOX/perovskite interface. In this study, a novel microstructure-control technology proposed for fabrication porous NiOX films using Pluronic P123 as structure-directing agent and acetylacetone (AcAc) coordination agent. synthesized enhanced hole extraction reduced reco...

Potassium sodium niobate (KNN) thin films are potentially useful for energy harvesting devices and lead-free piezoelectric microelectromechanical systems. This work reports the activation energies nucleation, growth perovskite phase transformation from a 0.5% manganese-doped KNN 2-methoxyethanol-based solution modified with acetylacetone excess alkali precursors. The were annealed in rapid ther...
