The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle.

The electronic spectrum of monomeric nickel(II) acetylacetonate and the infrared spectra of matrix-isolated acetylacetonates of cobalt(II), copper(II), and zinc(II)》 in relation to this compound, is published in Journal of Physical Chemistry. Let’s take a look at the latest research on this compound (cas:18362-64-6).

The uv electronic spectra of several Ni(II) β-ketoenolates in CHCl3 and hydrocarbon solvents are described and are shown to be consistent with the assignment of Cotton and Wise for the about 233- and 268-mμ bands. The vapor uv spectrum of Ni(II) acetylacetonate also shows these bands, as expected for a planar species. The ir spectra of CO2 matrix-isolated acetylacetonates of Cu(II), Ni(II), Co(II), and Zn(II) are reported between 650 and 2200 cm.-1 These spectra suggest the existence of similar (planar) structures for the Ni(II) and Cu(II) monomeric species and similar (tetrahedral) structures for the Zn(II) and Co(II) complexes. Since previous ir studies of metal acetylacetonates have ignored the fact that the anhydrous complexes are polymeric, it is fortunate that only minor differences exist between the spectra of the matrix-isolated Cu(II) complex, the complex which has received the greatest study, and the crystalline material.

The article 《Novel erbium(III) complexes with 2,6-dimethyl-3,5-heptanedione and different N,N-donor ligands for ormosil and PMMA matrices doping》 in relation to this compound, is published in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices. Let’s take a look at the latest research on this compound (cas:18362-64-6).

Three novel complexes, [Er(dmh)3(bipy)], [Er(dmh)3(bath)] and [Er(dmh)3(5NO2phen)], with 2,6-dimethyl-3,5-heptanedione (Hdmh) as the main sensitizer and either 2,2′-bipyridine (bipy), bathophenanthroline (bath) or 5-nitro-1,10-phenanthroline (5NO2phen) as synergistic ligands were synthesized. Upon excitation at the maximum absorption of the ligands, the complexes show the characteristic near-IR (NIR) luminescence of the Er3+ ions, due to efficient energy transfer from the ligands to the central Er3+ ion via the antenna effect. Single crystals were grown and their structures were determined showing different Er-N distances. The compound with shorter Er-N distances, [Er(dmh)3(5NO2phen)], is the best light harvester and the best for transferring the energy to the lanthanide among the three studied compounds Finally, the novel complexes were assessed for their application in sol-gel and polymer-based waveguides and optical amplifiers through their inclusion into ormosil and polymethylmethacrylate matrixes. The dispersion was successful in the bipy and 5NO2phen cases, with the properties of the hybrid materials mimicking those of the pure complexes.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 2,6-Dimethyl-3,5-heptanedione, is researched, Molecular C9H16O2, CAS is 18362-64-6, about Structure and NIR-luminescence of ytterbium(III) beta-diketonate complexes with 5-nitro-1,10-phenanthroline ancillary ligand: assessment of chain length and fluorination impact, the main research direction is ytterbium beta diketonate complex NIR luminescence ATR FTIR; crystal structure ytterbium phenanthroline fluorinated beta diketonate complex preparation.Recommanded Product: 18362-64-6.

Seven new tris(β-diketonate)ytterbium(III) complexes with the general formula [Yb(β-diketonate)3(5NO2phen)] [the β-diketone is 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione (1), 4,4,4-trifluoro-1-(2-furyl)-1,3-butanedione (2), 1,1,1-trifluoro-2,4-pentanedione (3), 1,1,1-trifluoro-5,5-dimethyl-2,4-hexanedione (4), 1,1,1,5,5,6,6,7,7,7-decafluoro-2,4-heptanedione (5), 2,4-hexanedione (6) or 2,6-dimethyl-3,5-heptanedione (7), and 5NO2phen = 5-nitro-1,10-phenanthroline] were synthesized and characterized by elemental anal., attenuated total reflectance-FTIR and photoluminescence spectroscopy. Single crystal x-ray structures have been determined for three fluorinated complexes (3-5) and ground state geometries of the other four complexes have been predicted using the Sparkle/PM6 model (1-2, 6-7). These exptl. and semi-empirical structures reveal octacoordination around the Yb3+ ion. Photoluminescence studies and lifetime measurements show that the increase in the fluorinated β-diketonate chain length is associated with a decrease in Yb3+ luminescence intensity of the 2F5/2 → 2F7/2 transition at ∼980 nm and the 2F5/2 excited state lifetime, while the ligand lifetime value remains almost unaffected. Finally, fluorination of the ligands is only advised when the complexes are to be used for co-doping with isostructural Er3+ complexes for optical amplifiers, since it leads to a slight decrease in luminescence intensity for the same β-diketonate chain length.

A general and efficient phosphorous acid-catalyzed cyclocondensation of β-ketoesters with o-aminobenzamides via selective C-C bond cleavage leading to quinazolinones is developed. This reaction proceeds smoothly under metal- and oxidant-free conditions, giving both 2-alkyl- and 2-aryl-substituted quinazolinones in excellent yields. This strategy can also be applied to the synthesis of other N-heterocycles, such as benzimidazoles and benzothiazoles.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Effect of selected β-diketones on lithium fluxes of bovine red blood cells, published in 1973, which mentions a compound: 18362-64-6, Name is 2,6-Dimethyl-3,5-heptanedione, Molecular C9H16O2, Application of 18362-64-6.

Dipivaloylmethane [1118-71-4] added to the medium containing lithium [7439-93-2]-loaded bovine erythrocytes removed Li from these cells. Results were compared in terms of the Li removal parameter as a function of the effective external Li concentration in the presence and absence of dipivaloylmethane. The effect of increasing initial external Li concentration was to decrease the Li removal parameter, and the maximum effect was observed with an initial external Li concentration of 4mM.
