Bridging homogeneous and heterogeneous catalysis with MOFs: Cu-MOFs as solid catalysts for three-component coupling and cyclization reactions for the synthesis of propargylamines, indoles and imidazopyridines

Copper-containing MOFs are found to be active, stable and reusable solid catalysts for three-component couplings of amines, aldehydes and alkynes to form the corresponding propargylamines. Two tandem reactions, including an additional cyclization step, leads to the effective production of indoles and imidazopyridines. In particular, the lamellar compound [Cu(BDC)] (BDC = benzene dicarboxylate) is highly efficient for the preparation of imidazopyridines, although a progressive structural change of the solid to a catalytically inactive compact structure is produced, causing deactivation of the catalyst. Nevertheless, the phase change can be reverted by refluxing in DMF, which recovers the original lamellar structure and the catalytic activity of the fresh material. The use of [Cu(BDC)] for this reaction also prevents the formation of Glaser/Hay condensation products of the alkyne, even when the reaction is performed in air atmosphere. This is a further advantage of [Cu(BDC)] with respect to other homogeneous copper catalysts, for which the use of an inert atmosphere is necessary.

Copper catalyzed oxidative coupling of ortho-vinylanilines with N-tosylhydrazones: Efficient synthesis of polysubstituted quinoline derivatives

Efficient and general copper catalyzed oxidative cyclization of ortho-vinylaniline has been accomplished employing N-tosylhydrazone as coupling partner. Various substituted quinoline derivatives of biological importance were achieved in good to excellent yield. The important features are the high functional group tolerates, up-gradation to gram scale synthesis and possible one-pot synthesis of quinoline from corresponding carboxaldehyde. Synthetic potential of the obtained quinoline derivatives was demonstrated through C-H bond functionalization reaction. Furthermore, preliminary mechanistic investigation revealed the possible generation of non-stabilized diazo compound and imine derivative as potential intermediates as well as copper catalyzed electrocyclic reaction and oxidative aromatization.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of Bis(acetylacetone)copper, you can also check out more blogs aboutSafety of Bis(acetylacetone)copper

The oxidation of benzylic and secondary alcohols under homogeneous conditions was achieved at 40C using molecular oxygen as the oxidant in the presence of excess 2-methylpropanal and catalytic amount of Co(acac)2. The oxidation reactions were also carried out with a heterogeneous analogue of Co(acac)2 revealing that the supported cobalt polymer acts as an active and reusable catalyst.

Copper thin films prepared by chemical vapour deposition from copper (II) acetylacetonate

Copper thin films were prepared by a low-temperature atmospheric pressure chemical vapour deposition method. The raw material was copper (II) acetylacetonate. At a reaction temperature above 220 C, polycrystalline copper films can be obtained by hydrogen reduction of the raw material. The resistivity of the film was close to that for bulk copper.

Synthesis of CZTS nanoparticles for low-cost solar cells

In this work, uniformly sized Cu2ZnSnS4 (CZTS) nanoparticles with easy control of chemical composition were synthesized and printable ink containing CZTS nanoparticles was prepared for low-cost solar cell applications. In addition, we studied the effects of synthesis conditions, such as reaction temperature and time, on properties of the CZTS nanoparticles. For CZTS nanoparticles synthesis process, the reactants were mixed as the 2:1:1:4 molar ratios. The reaction temperature and time was varied from 220C to 320C and from 3 hours to 5 hours, respectively. The crystal structure and morphology of CZTS nanoparticles prepared under the various conditions were investigated by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM), and energy dispersive X-ray spectroscopy (EDS) was used for compositional analysis of the CZTS nanoparticles.

Line-beam scan irradiation for preparation of YBCO films with high-Jc by excimer-laser-assisted MOD (ELAMOD)

Preparation of epitaxial YBa2Cu3O7 (YBCO) films on cerium oxide-buffered sapphire (r-cut alpha-Al2O3) substrates by an excimer-laser-assisted metalorganic deposition (ELAMOD) is reported. The ELAMOD process has been developed to bring about the advantage of shorter heating time than that in the conventional metalorganic deposition; the coated films are irradiated by an excimer laser beam before firing. We initiated the ELAMOD-YBCO process using a homogenized 8-mm-square laser beam which irradiates the coated surface in a fixed substrate mode. In order to extend the process applicable to large-area films, a scan irradiation mode was employed and a high critical-current density over 6 MA/cm2 has been observed. In the process, an appropriate choice of laser energy is difficult but crucial to obtain YBCO films with high superconducting properties. Then, laser irradiation from backside of the substrate was examined and proved to be beneficial to extend the experimental window of the laser energy. Moreover, a newly developed ELAMOD process using a 90-mm-wide line-beam is also reported which has a potential ability for large-area applications.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Creation of RT-FM in CdO nanocrystalline powder by codoping with Cu and Gd: Effect of annealing in hydrogen atmosphere

Cadmium oxide codoped with Cu and Gd ions powders were synthesised by simultaneous thermal co-decomposition of a mixture of cadmium acetate dihydrate, bis(acetylacetonato)copper, and tris(acetylacetonato)gadolinium(III) complexes. The mass ratio of Cu/Cd is fixed while the Gd/Cd mass ratio varied systematically. The purpose of the present study is to prepare powders having room temperature ferromagnetic (RT-FM) properties. Thus, an amount from each powder was annealed in hydrogen atmosphere in order to study its influence on the magnetic properties. X-ray fluorescence (XRF) and X-ray diffraction (XRD) methods confirm the purity and the formation of single nanocrystalline structure of the as-prepared powders, thus, both Cu and Gd ions were incorporated into CdO lattice forming solid solutions. Magnetic measurements reveal that all doped CdO powders gained paramagnetic (PM) properties where the susceptibility increases linearly with increasing dopant Gd content; the measured effective magnetic moment of doped Gd3+ was 7muB. Furthermore, the created RT-FM is dependent on the Gd% doping level. Also, it was found that the hydrogenation of the powders slightly enhances their PM properties and strongly enhances or creates RT-FM. For hydrogenated CdO powder doped with 3.1% Gd, the coercivity (Hc), remanence (Mr), and saturation magnetization (Ms) were 283.2 Oe, 2.04 memu/g, and 6.67 memu/g, respectively. Also, under hydrogenation, the values of Hc, M r, and Ms were increased by ?145%, 476%, and 131%, respectively in comparison with as prepared. Thus it was proved, for the first time, the possibility of production of CdO with RT-FM, where magnetic characteristics can be tailored by doping and post treatment under H2 atmosphere, thus a new potential candidate to be used as a dilute magnetic semiconductor (DMS).

ALLYLIC VERSUS VINILIC OXIDATION OF CYCLOHEXENE PROMOTED BY TRANSITION METAL beta-DIKETONATES

We report the cyclohexene oxidation by molecular oxygen in the presence of several metal beta-diketonates. The catalytic conditions used showed an allylic/vinilic oxidation (ao/av) ratio equal 1.5. The complexes M(l)n were used with the metal ions Co(III), Ni(II), Pd(II), Cu(II), chelated with acetylacetone (AcAc), benzoylacetone (BeAc) and dibenzoylacetone (BeBe) as ligands. The oxidation selectivity of the studied system suggests a different allylic/vinylic pathway compared with that observed inprevious reports.
