Zatsikha, Yuriy V. published the artcileDevelopment of a Class of Easily Scalable, Electron-Deficient, Core-Extended Benzo-Fused Azadipyrromethene Derivatives (“”MB-DIPY””), Product Details of C8H4N2, the main research area is benzofused azadipyrromethene derivative MBDIPY.

We have developed a new synthetic strategy for the preparation of a series of isoindolin-1-imines and isoindolin-1-ones from aromatic ketones and phthalonitrile. Self-condensation reactions of these isoindolin-1-imines led to the formation of a novel class of benzo-fused, highly electron-deficient core-extended azadipyrromethene chromophores (“”MB-DIPY””). The influence of temperature, catalyst, and the template ions on the self-condensation reaction rate, yield, and stereoselectivity was examined in detail. New chromophores (sodium, zinc, and metal-free compounds) were characterized by NMR, UV-vis, fluorescence, high-resolution mass spectroscopies, and in many cases, X-ray crystallog. Their redox properties were probed by electrochem. and spectroelectrochem. approaches that revealed the remarkable electron-accepting nature of the new systems. Stepwise one- and two-electron reduction of the new MB-DIPYs and their zinc complexes was investigated by spectroscopic and spectroelectrochem. methods. Both one- and two-electron reduced forms of all zinc complexes studied have strong absorption in the near-IR region up to âˆ?200 nm. Unusual spectroscopic and electrochem. properties of these dyes were correlated with their electronic structures and excited-state natures predicted by d. functional theory (DFT) and time-dependent DFT calculations Despite some structural similarities with well-known aza-BODIPYs, the new MB-DIPYs differ remarkably from them in spectroscopic and redox properties.

Ocansey, Edward published the artcileIridium and Palladium CO2 Hydrogenation in Water by Catalyst Precursors with Electron-Rich Tetrazole Ligands, Quality Control of 100-70-9, the main research area is tetrazolylpyridyl iridium palladium complex preparation catalyst carbon dioxide hydrogenation; iridium chloride cyclometalation reaction tetrazolylpyridine ligand; palladium chloride cyclometalation reaction tetrazolylpyridine ligand.

Hydrogenation of CO2 to formate serves as a means of H2 storage. By using robust, electron-rich and bulky NN bidentate tetrazolylpyridyl ligands, the authors prepared CO2 hydrogenation Ir(III) and Pd(II) catalyst precursors (3-7) that operate in H2O as a solvent. In situ1H NMR spectroscopic data obtained when the hydrogenation catalyst is 5, detects a hydrido bridged binuclear Ir intermediate compound is formed prior to the formation of the catalytically active Ir hydride species. This hydrido bridged Ir intermediate is observable by in situ1H NMR spectroscopy even after extended periods of storage. Product formation in the CO2 hydrogenation, catalyzed by these tetrazolylpyridyl Ir and Pd catalysts, proceeds via either CO2 hydrogenation or NaHCO3 reduction

Babu, Venkata Nagarjuna published the artcileExocyclic N-Acyliminium Ion (NAI) Cyclization: Access to Fully Substituted Oxazoles and Furocoumarins, Application of Picolinonitrile, the main research area is one pot synthesis oxazole furocoumarin UV vis fluorescence study; exocyclic acyliminium ion intermediate cyclization.

A concise, one-pot route to oxazoles and furocoumarins has been reported. The key step in this transformation involves in situ generation of N-acyliminium ion (NAI) precursor under catalyst and solvent-free conditions and their further transformations promoted by superacid in the same pot. We have also presented the exptl. evidence for the involvement of proto-solvated novel exocyclic N-acyliminium ion. Further, the UV-visible and fluorescence studies revealed that few of the compounds reported here exhibited emission of blue light upon irradiation in EtOH in the region of 404-422 nm.

Kajiwara, Rikuo published the artcileBipyridine-Type Bidentate Auxiliary-Enabled Copper-Mediated C-H/C-H Biaryl Coupling of Phenols and 1,3-Azoles, Quality Control of 87150-13-8, the main research area is heterobiaryl preparation; phenol azole coupling bipyridine type bidentate auxiliary copper.

A copper-mediated dehydrogenative C-H/C-H biaryl coupling of phenols and 1,3-azoles has been developed. The key to its success is the introduction of a bipyridine-type bidentate auxiliary, 4,4′-di(tert-butyl)-2,2′-bipyridine, on the phenol oxygen, which is readily prepared and easily attachable, detachable, and recyclable. The reaction proceeds smoothly in the presence of copper salt alone to form the corresponding phenol-azole heterobiaryls, which are prevalent motifs in functional mols. such as excited-state intramol. proton transfer materials.

To alleviate diffusion-limited photoinduced electron transfer (PET) in solution, a triphenylamine-derived dye and a Keggin polyoxometalate-type electron relay were coupled into a coordination polymer to photoinduce long-lived charge-separation pairs with enough reductive/oxidative potential to pump multiple electrons unidirectionally from external electron donors to acceptors, thus furnishing photocatalytic radical couplings to afford value-added α-amino C-H arylation products.

Zhao, Ziming published the artcilePreparation of a magnetic mesoporous Fe3O4-Pd@TiO2 photocatalyst for the efficient selective reduction of aromatic cyanides, Recommanded Product: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is iron oxide palladium titania mesoporous composite photoreduction photocatalyst hydrogenation.

Herein, a hierarchical magnetic mesoporous microsphere was successfully prepared as a photocatalyst via a simple and reproducible route. Typically, Pd nanoparticles (NPs) were evenly dispersed on the surface of a magnetic Fe3O4 microsphere and then coated with a porous anatase-TiO2 shell to form Fe3O4-Pd@TiO2. The core-shell structure could efficiently suppress the conglomeration of Pd NPs during the calcination process at high temperatures as well as the shedding of Pd during the catalytic reaction process in the liquid phase. The as-prepared photocatalyst was characterized by TEM, XRD, XPS, VSM, and N2 adsorption-desorption. Fe3O4-Pd@TiO2 exhibits high photocatalytic activity for the selective reduction of aromatic cyanides to aromatic primary amines in an acidic aqueous solution Moreover, this magnetic photocatalyst could be easily recovered from the reaction mixture by an external magnet and reused five times without significant reduction in its activity. The superior photocatalytic efficiency of the proposed photocatalyst may be attributed to its high charge separation efficiency and charge transfer rate, which are caused by the Schottky junction and large interface area. The results indicate that the strategy of coating the active noble metal sites with a mesoporous semiconductor shell has a significant potential for application in metal-semiconductor-based photocatalytic reactions.

Moeini, Nazanin published the artcileSynthesis and characterization of magnetic Fe3O4@Creatinine@Zr nanoparticles as novel catalyst for the synthesis of 5-substituted 1H-tetrazoles in water and the selective oxidation of sulfides with classical and ultrasonic methods, Product Details of C8H4N2, the main research area is magnetic creatinine zirconium nanoparticle sulfoxidation cycloaddition catalyst sulfoxide tetrazole.

Tetrazoles and sulfoxide compounds have a wide range of applications in industries and are of great expectation to be environmentally friendly and cost-effective. This paper reports the introduction of zirconium supported on Fe3O4 nanoparticles through creatinine post-functionalization modification of Fe3O4 (Fe3O4@Creatinine@Zr). The Fe3O4@Creatinine@Zr was characterized by a vibrating sample magnetometer, X-ray powder diffractometry, Fourier transforms IR, scanning electron microscope, energy dispersive X-Ray anal., thermogravimetric anal., and inductively coupled plasma. Fourier transform-IR spectroscopy results confirmed that creatinine was successfully immobilized on the surface of Fe3O4-Cl with the presence of ν(C = N), and ν(C = O) bands of creatinine. X-ray diffraction data confirmed that the crystalline phase of Fe3O4 was not destroyed after modification. Vibrating sample magnetometer anal. showed that the saturation magnetization of the Fe3O4@Creatinine@Zr was 28.6 emu/g. The SEM-EDX results revealed that the zirconium complex was successfully incorporated into the structure of Fe3O4. This catalyst displayed high catalytic performance in the synthesis of 5-substituted 1H-tetrazoles and the selective oxidation of sulfides with classical and ultrasonic methods. The catalyst conferred strong Lewis’s acidity sites for the activity and selectivity of the reactions. The obtained results showed that the fast oxidation of sulfides occurred with 0.2 mmol g -1 of zirconium immobilized on the Fe3O4 nanoparticle at optimum condition (sulfide (1 mmol), H2O2 (0.6 mL), ethanol (3 mL) and catalyst (Fe3O4@Creatinine@Zr, 60 mg) at room temperature). The results showed that ultrasonic was an appropriate method for the oxidation of sulfides to the related sulfoxide at the optimum condition. The 5-substituted 1H-tetrazoles were afforded at optimum condition (nitrile (1 mmol), NaN3 (1.2 mmol), H2O (3 mL), catalyst (100 mg) at 90°C). The catalyst was separated by simple recovery and reused for seven cycles without any remarkable decrease in the catalysis activity and selectivity. The output of this research can open a window for the synthesis the other organic materials under mild condition.
