In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis and pharmacological evaluation of antioxidant chalcone derivatives of 2(3H)-benzoxazolones, published in 2009, which mentions a compound: 54903-09-2, mainly applied to chalcone derivative benzoxazolone preparation antioxidant activity, Synthetic Route of C9H7NO3.

Chalcones featuring an analgesic/anti-inflammatory pharmacophore, i.e., the 2(3H)-benzoxazolone heterocycle, on the one hand, and a radical scavenger moiety, i.e., 2,6-di-t-butylphenol, on the other hand were synthesized by condensation of a ketone 2(3H)-benzoxazolone precursor with 3,5-di-t-butyl-4-hydroxybenzaldehyde. Among the various methods explored (acid homogeneous or heterogeneous catalysis, base catalysis), heterogeneous catalysis conditions using KSF Montmorillonite were found to be the most convenient. The E-geometry of the so-obtained chalcones was ascertained both by 1H and 13C-NMR spectroscopy as well as B3LYP/6-31G** quantum mechanics calculations Eight chalcones, e.g. I, were pharmacol. evaluated in vitro for their ability to prevent human low-d. lipoprotein (LDL) copper-induced oxidation using Cu2+ as oxidizing agent. I emerged as the most promising agent as it was able to inhibit copper-mediated human LDL oxidation with an activity ten times greater than that of Probucol, a reference antioxidant drug.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures.

Aromatic N-heterocycle-fused scaffolds such as indoles and quinolines I (R1 = H, 5-Me, 6-NH2, etc.; R2 = H, 2-Me, 2-C6H5, etc.; X = C, N) are important core structures found in various bioactive natural products and synthetic compounds Recently, various dehydrogenation methods with the help of alkoxides, known to significantly promote dihydro- or tetrahydro-heterocycles to be oxidized, were developed for the heterocycle synthesis. However, these approaches are sometimes unsuitable due to resulting undesired side reactions such as reductive dehalogenation. Herein, expedient syntheses of 1H-indoles, quinolines, and 6-membered N-heterocycle-fused scaffolds from their hydrogenated forms through palladium(II)-catalyzed aerobic dehydrogenation under alkoxide-free conditions are reported. A total of 48 compounds were successfully synthesized with a wide range of functional groups including halogens (up to 99% yield). These methodologies provide facile routes for various privileged structures possessing aromatic N-heterocycles without the help of alkoxides, in highly efficient manners.

High-performance and long-term stable self-powered photodetectors (PDs) based on methylammonium lead iodide nanowires (NWs) are demonstrated by incorporating n-type conjugated polymer poly{2,5-bis(2-dodecylhexadecyl)-3,6-di(thiophen-2-yl)pyrrolo-[3,4-c]pyrrole-1,4(2H,5H)-dione-alt-(E)-1,2-bis(3-cyanothiophen-2-yl)ethene} (DPP-CNTVT) as multi-functional interfacial layer. Incorporating DPP-CNTVT with abundant Lewis base functional groups can effectively passivate under-coordinated Pb2+ defects, enabling perovskite NWs to exhibit remarkable stability and optoelectronic properties. Meanwhile, high electron mobility, together with the proper energy level of DPP-CNTVT, makes it ideal for use as an electron transport layer. Particularly, by taking advantage of the low bandgap of DPP-CNTVT, the utilization of low energy photons can be improved. The resulting PDs exhibit responsivity up to 0.50 A W-1, specific detectivity approaching 1014 Jones, and a wide linear dynamic range of nearly 265 dB under zero bias operation, which represent the best results ever reported for self-powered perovskite PDs. More encouragingly, with the incorporation of an appropriate encapsulation layer, nearly 90% of the initial detectivity of PDs can be secured after 15 300 h of continuous operation in ambient conditions. The application of NWs PDs for solution-processed reflective-mode pulse oximetry is also demonstrated. This study provides valuable insights into developing efficient and ultra-stable self-powered perovskite PDs through interfacial engineering, which can accelerate the practical applications of this emerging technol.

Author is Camasso, Nicole M.; Sanford, Melanie S..

Homogeneous nickel catalysis is used for the synthesis of pharmaceuticals, natural products, and polymers. These reactions generally proceed via nickel intermediates in the Ni0, NiI, NiII, and/or NiIII oxidation states. In contrast, NiIV intermediates are rarely accessible. Authors report herein the design, synthesis, and characterization of a series of organometallic NiIV complexes, accessed by the reaction of NiII precursors with the widely used oxidant S-(trifluoromethyl)dibenzothiophenium triflate. These NiIV complexes undergo highly selective carbon(sp3)-oxygen, carbon(sp3)-nitrogen, and carbon(sp3)-sulfur coupling reactions with exogenous nucleophiles. The observed reactivity has the potential for direct applications in the development of nickel-catalyzed carbon-heteroatom coupling reactions.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1,10-Phenanthroline(SMILESS: C1=CC3=C(C2=NC=CC=C12)N=CC=C3,cas:66-71-7) is researched.Recommanded Product: 16004-15-2. The article 《Mixed-Ligand Uranyl Squarate Coordination Polymers: Structure Regulation and Redox Activity》 in relation to this compound, is published in Inorganic Chemistry. Let’s take a look at the latest research on this compound (cas:66-71-7).

The electron-rich squarate ion (C4O42-, SA2-) possesses electronic delocalization over the entire mol. and good redox activity, and the functionalization of metal-organic complexes with the SA2- group is desirable. In this work, a mixed-ligand method is used to construct novel uranyl squarate coordination polymers utilizing 4,4′-bipyridine (bpy), 4,4′-bipyridine-N,N’-dioxide (bpydo), 1,10-phenanthroline (phen), 4,4′-vinylenedipyridine (vidpy), and in situ formed oxalate (OA2-) as ancillary ligands. Seven mixed-ligand uranyl compounds, [(UO2)(OH)(SA)](Hbpy) (1), [(UO2)(H2O)(SA)2](H2bpy) (2), (UO2)(H2O)(SA)(bpydo)·2H2O (3), (UO2)(H2O)(SA)(phen)·H2O (4), (UO2)(OH)(SA)0.5(phen)·H2O (5), [(UO2)(SA)(OA)0.5](Hphen) (6), and [(UO2)(SA)(OA)0.5](Hvidpy) (7), with varying crystal structures were synthesized under hydrothermal conditions. Compound 1, together with bpy mols. filling in the interlayer space as template agents, has a two-dimensional (2D) network structure, while 2 gives a one-dimensional (1D) chain based on mononuclear uranium units. Compound 3 shows a neutral 2D network through the combined linkage of SA2- and bpydo. Both 4 and 5 have a similar chain-like structure due to the capping effect of phen motifs, while phen mols. in 6 act as templating agents after protonation. Similar to 6, compound 7 has a “”sandwich-like”” structure in which the Hvidpy motifs locate in the voids of layers of 2D uranyl-squarate networks. The redox properties of typical mixed-ligand uranyl-squarate compounds, 1, 4, and 5 with high phase purity, are characterized using cyclic voltammetry. All three of these uranyl coordination compounds show anode peaks (Ea) at 0.777, 0.804, and 0.760 V, resp., which correspond to the oxidation process of SA2- → SA. Meanwhile, cathodic peaks (Ec) at -0.328, -0.315, and -0.323 V corresponding to the reduction process of U(VI) → U(V) are also observed The results reveal that all three of these uranyl coordination compounds show good redox activity and, most importantly, the interplay between two different redox-active motifs of SA2- organic linker and uranyl node. This work enriches the library of redox-active uranyl compounds and provides a feasible mixed-ligand method for regulating the synthesis of functional actinide compounds
