A highly effective green catalyst Ni/Cu bimetallic nanoparticles supported by dendritic ligand for chemoselective oxidation and reduction reaction

The highly active Ni/Cu bimetallic nanoparticles (NPs) of the different molar ratios of Ni and Cu (1:1, 1:3, 3:1) assisted by dendritic ligand 2,4,6-Tris (di-4-chlorobenzamido)-1,3-diazine were synthesized successfully confirmed by Scanning Electron Microscopy (SEM), Electron Diffraction X-ray (EDX), X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD), and Transmission Electron Microscopy (TEM) analysis. These NPs were studied as a heterogeneous catalyst for the chemoselective oxidation of alcohol to the corresponding aldehyde at 30 min and chemoselective reduction of aromatic nitro substituents to the corresponding amino substituents at 20 min, while the Ni/Cu (3:1) NPs were found to be the most effective among other Ni/Cu (1:1) and Ni/Cu (1:3) NPs at room temperature under mild conditions. The Ni/Cu (3:1) NPs can be recycled for at least five successive runs with no perceptible decrease in catalytic activity. Graphic abstract

Dinuclear mixed valence cobalt(II/III) and hetero-tetranuclear cobalt(III)/Na complexes with a compartmental ligand: Synthesis, characterization and use as catalysts for oxidative dimerisation of 2-aminophenol

A N2O4 donor compartmental reduced Schiff base ligand, H2L [(2,2-dimethyl-1,3-propanediyl)bis(iminomethylene)bis(6-methoxyphenol)], obtained on 1:2 condensation of 2,2-dimethyl-1,3-propanediamine with ortho-vanillin followed by reduction with NaBH4 in methanol solution, has been used to prepare two cobalt complexes, [(N-3)(CoL)-L-III(mu-OAc)Co-II(N3)] (1) and [(mu-N-3)(2){(AcO)(CoLNa)-L-III(CH3OH)}(2)]2CH(3)OH (2). Complex 1 is a dinuclear mixed valence cobalt(III)/cobalt(II) complex with (CoO2CoII)-O-III core. Complex 2, on the other hand, is a tetranuclear cobalt(III)/sodium complex with CoO2Na(N-3)(2)NaO2Co core. Formation of complex 1 or 2 is mainly governed by the amount of cobalt(II) precursors present in the reaction mixture. Each complex has been characterized by elemental and spectral analysis. X-ray diffraction analysis has confirmed their structures. Complex 1 crystallized in a chiral space group Pna21 where both the cobalt(III) and cobalt(II) centers adopt six-coordinate distorted octahedral geometry with cobalt(III) and cobalt(II) centers residing respectivelyat inner N2O2 and outer O-4 cavities of the reduced Schiff base. Complex 2 crystallized in triclinic system with P1space group, where both cobalt(III) and sodium centers adopt distorted octahedral geometry. Oxidation states of cobalt centers have been confirmed by bond length consideration, BVS calculations as well as from room temperature magnetic moment measurement. Both complexes 1 and 2 show phenoxazinone synthase mimicking activity with kcat values 250.21 and 493.73 h(-1) respectively.

Reaction mechanism of regioisomerization in binuclear (diaminocarbene) Pd-II complexes

A series of binuclear Pd-II carbene complexes were synthesized via the treatment of cis-[PdCl2(CNXyl)(2)] (1) with benzo-1,3-thiazol-2-amines (2-6) and structurally characterized. In every case the reaction leads to the mixture of two regioisomers, which are able to interconvert. The study of the regioisomerization of the binuclear diamino-carbene species showed that it is a first-order reaction, that is, it occurs intramolecularly, and was analyzed with the Hammett function. Electron-withdrawing substituents in the benzothiazole moiety of the complexes as well as increasing the solvent polarity accelerate the reaction. The solvent donor strength correlates less well with the isomerization rates. Based on the obtained activation parameters the studied regioisomerization could be defined as the interchange/dissociative process type. A combined approach including kinetic and mass spectrometric studies allowed the conclusion that the rate-determining step of the isomerization is breaking the carbon-nitrogen bond in the carbene fragment of the binuclear complex.

Copper(I) Complex of Dihydro Bis(2-Mercapto Benzimidazolyl) Borate as an Efficient Homogeneous Catalyst for the Synthesis of 2H-Indazoles and 5-Substituted 1H-Tetrazoles

In this work, catalytic activity of a series of copper(I) complexes containing dihydrobis(2-mercapto-benzimidazolyl) borate (Bb), and phosphine co-ligands was investigated in the synthesis of N-heterocycle compounds including 2H-indazoles and 5-substituted 1H-tetrazoles. The copper(I) complex containing tricyclohexylphosphine co-ligand, [Cu(Bb)(PCy3)], displayed the highest catalytic activities for the formation of 2H-indazoles and 1H-tetrazoles. Apart from the nontoxicity and strong sigma-donating ability of the introduced ligands, the introduced catalyst required easy handling processes. The catalytic reactions were successfully performed at low catalyst loadings in either PEG-200 or DMF and in relatively short reaction times. The diversity of these reactions was also explored with 20 and 12 examples. Finally, the current catalytic system is amenable to large-scale production of these N-heterocycle compounds.

Combining hydrogen bonding interactions with steric and electronic modifications for thermally robust alpha-diimine palladium catalysts toward ethylene (co)polymerization

Development of thermally robust palladium-based catalysts for (co)polymerization of ethylene and polar monomers with high activities is a continuing challenge. Combining hydrogen bonding interactions with steric and electronic modifications, dibenzobarrelene-based alpha-diimine palladium complexes with different substituents (X = OMe, H, Cl, Br, and I) have been synthesized and characterized. The steric effect of the palladium complexes was elucidated by their buried volumes, and the electronic effect of the substituents was clarified by the Hammett constants (sigma) of the substituents and H-1 NMR analysis of the Pd-bound methyl. The hydrogen bonding interactions (H center dot center dot center dot Cl and H center dot center dot center dot OMe) were confirmed by single crystal structures of chloro- and methoxy-substituted neutral and cationic palladium complexes. Contributed by the steric and electronic effects as well as the hydrogen bonding, the chloro-substituted palladium catalyst was thermally robust at temperatures as high as 100 degrees C for ethylene polymerization, while the methoxy-substituted palladium catalyst showed excellent tolerance toward high temperature and polar groups and was able to copolymerize ethylene and methyl acrylate (MA) at 80 degrees C to produce the copolymer with high MA incorporation up to 9.5 mol%.

In Situ Ligand-Transformation-Involved Synthesis of Inorganic-Organic Hybrid Polyoxovanadates as Efficient Heterogeneous Catalysts for the Selective Oxidation of Sulfides

By intentionally involving in situ ligand transformation in the reaction system, two inorganic-organic hybrid polyoxovanadates (POVs), [Co(HDTBA)V2O6] (1) and [Ni(H2O)(2)(DTBA)(2)V2O4(OH)(2)]center dot 4H(2)O (2), have been synthesized by using a hydrothermal method, where the 3,5-di[1,2,4]triazol-1-ylbenzoic acid (HDTBA) ligand originated from in situ hydrolysis of 3,5-di[1,2,4]triazol-1-ylbenzonitrile in the self-assembly process. The inorganic layers [Co-2(V4O12)](n) containing [V4O12](4-) circle clusters were linked by HDTBA ligands to yield a 3D framework structure of compound 1. There existed a kind of binuclear [(DTBA)(2)V2O4(OH)(2)](2-) vanadium cluster grafted directly by two DTBA ligands through the sharing of carboxyl oxygen atoms in compound 2, further extended into a 2D layer by nickel centers. The investigations on the catalytic properties indicated that compounds 1 and 2 as heterogeneous catalysts, especially 2, owned satisfying catalytic performances for catalyzing the selective oxidation of sulfides to sulfoxides in the presence of tert-butyl hydroperoxide as an oxidant, accompanied by excellent conversion of 100% and selectivity of above 99%, providing a promising way for developing inorganic-organic hybrid POVs as effective heterogeneous catalysts for catalyzing the selective oxidation of sulfides.

Structural basis for substrate specificity of L-methionine decarboxylase

L-Methionine decarboxylase (MetDC) from Streptomyces sp. 590 is a vitamin B-6-dependent enzyme and catalyzes the non-oxidative decarboxylation of L-methionine to produce 3-methylthiopropylamine and carbon dioxide. We present here the crystal structures of the ligand-free form of MetDC and of several enzymatic reaction intermediates. Group II amino acid decarboxylases have many residues in common around the active site but the residues surrounding the side chain of the substrate differ. Based on information obtained from the crystal structure, and mutational and biochemical experiments, we propose a key role for Gln64 in determining the substrate specificity of MetDC, and for Tyr421 as the acid catalyst that participates in protonation after the decarboxylation reaction.
