Flavonoids are a class of natural products, found in a wide range of vascular plants and dietary components. Their low toxicity and extensive biological activities, including anti-cancer and anti-bacterial, have made them attractive candidates to serve as therapeutic agents for many diseases. Herein, we disclose a highly efficient synthetic method of CuI-catalyzed cascade oxa-Michael-oxidation, using chalcones as substrates, mediated by the ionic liquid [bmim][NTf2] at a low temperature. This efficient synthetic method has demonstrated high synthetic utility and can afford flavones in good to high yields (up to 98%).

CuO and Cu2O nano/microparticles with pure phases have been synthesized from the same precursor by a hydrothermal method. Hydrothermal heating of Cu(OAc)2 produced CuO at 125 C whereas pure Cu2O was obtained at 175 C. Heating at 150 C gave a CuO/Cu2O mixture. In contrast, Cu(acac)2 produced only Cu2O at all three temperatures. The pure phases of Cu2O and CuO nano/microparticles were confirmed by PXRD and XPS characterization. The mechanistic studies indicate that decomposition of the organic anion/ligand of the Cu-precursor played a key role in the formation of CuO/Cu2O nano/microparticles from Cu(OAc)2/Cu(acac)2. FE-SEM studies revealed the formation of CuO with a microsphere morphology (125 C) and a micro-cup for Cu2O at 175 C. Nanowires and micron-sized elliptical cylinders were observed for Cu2O synthesized from Cu(acac)2. However, calcination of Cu(OAc)2, Cu(acac)2 and Cu(NO3)2 at 500 C produced crystalline CuO nano/microparticles with various sizes and morphologies. Further, CuO nano/microparticles investigated for industrially important aromatic nitro to amine conversion showed morphology dependent nitro group reduction. Smaller spherical CuO nano/microparticles obtained from Cu(acac)2 exhibited the highest catalytic activity. The reusability studies indicate that CuO nano/microparticles can be used for up to six cycles. Thus we have presented a simple method to synthesize Cu2O or CuO from the same precursor and demonstrated the morphology dependent catalytic activity of CuO nano/microparticles.

The central copper(II) ion is coordinated by two oxygen atoms and two nitrogen atoms of two acetylacetone phenylhydrazone ligands. The Cu(phac)2 molecules are linked in layers parallel to the Oyz plane. The oxygen atoms of the ketone fragment are involved in intermolecular bonding, which completes the coordination sphere of the central copper(II) ion to a substantially elongated octahedron. The thermal stability of the Cu(phac)2 complex was estimated under nitrogen at atmospheric pressure and in vacuo.

The reactions of tetraphenylporphine (H2TPP) with copper(II) chelates in DMSO were studied. alpha-Amino acids (glycine, alpha-alanine, valine, leucine, tyrosine, and glutamine) were used as chelating ligands. The study of the reaction kinetics showed that Cu(II) chelates with alanine and the other amino acids are less reactive in these reactions than acetylacetonates, alpha-nitroso-beta-naphtholates, and hydroxyquinolates. The exception is a Cu(II) complex with tyrosine. The relationship between the structure of the above chelates and the rate of their reactions with porphyrin was determined.

Synthetic Route of 13395-16-9, As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, once mentioned the application of Synthetic Route of 13395-16-9, Name is Bis(acetylacetone)copper,molecular formula is C10H16CuO4, is a conventional compound. this article was the specific content is as follows.

Addressed herein is the composition-controlled catalysis of CuPd alloy nanoparticles (NPs) supported on reduced graphene oxide (RGO) in the hydrolytic dehydrogenation of ammonia borane (AB). Nearly monodisperse CuPd alloy NPs were synthesized by using a surfactant-assisted organic solution phase protocol comprising the co-reduction of acetylacetonate complexes of Pd and Cu by morpholine borane complex in oleylamine and 1-octadecene at 80 C. The presented recipe allowed us to make a composition control over the CuPd alloy NPs. Three different compositions of CuPd alloy NPs (2.7 nm Cu30Pd70, 2.9 nm Cu48Pd52, 3.0 nm Cu75Pd25) could be prepared among which the Cu75Pd25 NPs showed the best catalytic performance in hydrogen generation from the hydrolysis of AB. Among the various support materials tested for as-prepared Cu75Pd25 alloy NPs, the RGO-Cu75Pd25 catalysts showed the highest performance in the hydrolysis of AB. Moreover, the activity of the RGO-Cu75Pd25 catalysts were dramatically enhanced by annealing them at 400 C for 1 h under Ar-H2 (5% H2) gas flow and an unprecedented TOF value of 29.9 min-1 was obtained in the hydrolysis of AB at room temperature. The reported TOF value here is much higher than RGO-Cu (TOF = 3.61 min-1) and even higher than RGO-Pd catalysts (TOF = 26.6 min-1). The detailed kinetics of RGO-Cu75Pd25 catalyzed AB hydrolysis was also studied depending on catalyst concentration, substrate concentration and temperature. The apparent activation energy of the catalytic hydrolysis of AB was calculated to be 45 ± 3 kJ mol-1.

The magnetic properties of chalcogenide spinel CuCr2Se4 nanocrystals have been studied as a function of crystallite size (15-30 nm). A solution-based method is used for the facile synthesis of the nanocrystals with good size control. They have close to cubic morphology with a narrow size distribution and exhibit superparamagnetic behavior at room temperature. The Curie temperature and saturation magnetization of the nanocrystals are lower as compared with the bulk and decrease with decreasing nanocrystal size. A similar trend is observed in the paramagnetic state for the Curie-Weiss temperature and effective magnetic moment. The low temperature magnetization behavior can be qualitatively explained by spin glass dynamics.

A selective CVD system used to deposit the central metal of a volatile complex preferentially on catalytically active substrate surfaces was examined.Copper(II) acetylacetonate was vaporized in a flow of hydrogen and decomposed on Ni, Pd, and Al plates in order to deposit metallic copper.When a Ni plate was used as the substrate, deposition of metallic copper occurred at temperatures in the range 130-180 deg C only on the substrate surfaces.The formation of an ultrathin film of Cu of uniform thickness was confirmed.On a Pd substrate, the formation of an ultrathin Cu film of uniform thickness was also observed.On an Al substrate, however, deposition occurred nonselectively at temperatures above 160 deg C, not only on the substrate surface, itself, but also on the wall of the glass tube as well as the quartz wool surrounding the Al plate.In addition, the formation of fine particles of Cu, instead of thin film, was found to exist on the substrate.Because the deposition of Cu took place on catalytically active surfaces selectively, the deposition was considered to proceed by a catalytic hydrogenation of the C=O bond of the ligand, thus detaching it from the Cu ion and allowing it to decompose the complex and deposit Cu metal.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 13395-16-9 is helpful to your research.
