Two lanthanide coordination polymers, namely, {[La(TTTA)(H 2O)2]·2H2O}n (La-TTTA) and [Nd(TTTA)(H2O)2]·2H2O}n (Nd-TTTA) have been hydrothermally synthesized through th

A porous two-dimensional (2D) metal-organic framework (MOF), namely, [Cd(PBA)(DMF)]·DMF (Cd-PBA), has been solvothermally synthesized by the reaction of 5-(4-pyridin-3-yl-benzoylamino)-isophthalic acid ligand (H2PBA) and Cd(II) ions. Structural

A novel selective nanoscale etching process that generated a well defined hollow nanostructure was developed by treating manganese oxide nanoparticles with a hydroxylamine solution. This selective etching process was used for exploiting a novel method of differentially functionalizing the internal surface of a hollow silica shell with a catalytically active Mn3O 4 layer and creating a novel nanoreactor framework. The nanoreactor fabricated by the newly developed method catalyzed the cyanosilylation reactions of various aromatic aldehydes with size and shape selectivity. Moreover, the substrate selectivity in the cyanosilylation reactions was efficiently tuned by modifying the outer silica shell with silane coupling reagents.

Zinc paddlewheel metal-organic frameworks (MOFs) frequently exhibit low stability or complete collapse upon the removal of axial ligands. Hence, there are very few reports on gas adsorption of zinc paddlewheel MOFs. In this work, the N2 and Hs

New monomeric O,N-heterocyclic germylene AdAPGe (1) based on 4,6-di-tert-butyl-N-adamantyl-o-aminophenol is synthesized and structurally characterized. Germylene 1 in the crystal demonstrates weak Ge?Ge interactions between adjacent molecules. The redox activity of compound 1 and its known analogs PhAPGe (2), t-BuAPGe (3) was studied using cyclic voltammetry and chemical oxidation by the phenoxy radical. Germylene 1, as opposed to 2 and 3, was found to form a relatively stable o-iminosemiquinonate moiety during oxidation. The last one was detected by EPR spectroscopy in toluene solution at low temperatures. The catalytic activity of germylenes 1-3 and dippAPGe (4) (dipp-2,6-di-isopropylphenyl) towards hydroboration and cyanosilylation of benzaldehyde was examined. Germylene 1 demonstrates the most potent promoter properties for such reactions, which allowed cyanosilylation and hydroboration of aldehyde under mild conditions with excellent conversion quickly. Theoretical studies were performed to establish the mechanism, and different reaction routes were examined. According to the DFT (B3LYP/def2-SVP) calculation, cyanosilylation and hydroboration processes are initiated by coordinating TMSCN or HBpin with the catalyst. The followed reaction with aldehyde leads to the resulting products.
Valmet Chiral Schiff-Base Ligands And Their Copper(II) Complexes as Organo, Homogeneous and Heterogeneous Catalysts for Henry, Cyanosilylation and Aldol Coupling Reactions

Cyanosilylation, aldol coupling and asymmetric Henry reactions were carried out with L- and D-valmet ligands in different configurations: i) coordinated to sodium ions, as organocatalysts, with week base properties, ii) complexes with copper(II), as homogeneous catalysts, and iii) immobilized copper(II) complexes onto graphene oxide (GO) as heterogeneous catalysts. For the reaction of benzaldehyde and nitromethane in water these afforded an asymmetric Henry reaction, with a spectacular increase of the conversion and ee (92.5 and 95.8 %, respectively) after the deposition on GO. Ligand complexed copper was also effective for cyanosilylation and Aldol coupling reaction.
