Heteronuclear 3 d/DyIII Coordination Clusters as Catalysts in a Domino Reaction

by Kieran Griffiths, Christopher W. D. Gallop, Alaa Abdul-Sada, Alfredo Vargas, Oscar Navarro, George E. Kostakis

Abstract

Three isoskeletal tetranuclear coordination clusters with general formula [MII2DyIII2L4(EtOH)6](ClO4)2⋅2 EtOH, (M=Co, 1; M=Ni, 2) and [NiII2DyIII2L4Cl2(CH3CN)2]⋅2 CH3CN (3), have been synthesized and characterized. These air-stable compounds, and in particular 3, display efficient homogeneous catalytic behavior in the room-temperature synthesis of trans-4,5-diaminocyclopent-2-enones from 2-furaldehyde and primary or secondary amines under a non-inert atmosphere.

Preparation of Iron-Containing Schiff Base and Ionic Liquid Based Bifunctional Periodic Mesoporous Organosilica and Its Application in the Synthesis of 3,4-Dihydropyrimidinones

by Dawood Elhamifar, Elham Nazari

Abstract

A novel iron-containing Schiff base and ionic liquid based bifunctional periodic mesoporous organosilica (Fe@SBIL-BPMO) was prepared, characterized, and its catalytic application was developed. The SBIL-BPMO was first prepared by the grafting of 3-aminopropyltrimethoxysilane on an ionic-liquid-based PMO followed by treatment with 2-hydroxybenzaldehyde in toluene at reflux. This material was then reacted with Fe(NO3)39 H2O to afford the Fe@BPMO-SBIL nanocatalyst. The catalyst was characterized by thermogravimetric analysis, nitrogen sorption experiments, diffuse reflectance FTIR spectroscopy, low-angle powder XRD, and TEM. The Fe@SBIL-BPMO catalyst was successfully applied in the one-pot synthesis of 3,4-dihydropyrimidinone/thione derivatives under solvent-free reactions. The stability, reactivity, and reusability of the catalyst under the reaction conditions have also been investigated.

Hard graft: A novel iron-containing Schiff base and ionic liquid based bifunctional periodic mesoporous organosilica (Fe@SBIL-BPMO) was prepared and characterized, and its catalytic application was investigated in the one-pot three-component Biginelli reaction (see picture). The catalyst illustrated excellent reactivity, recoverability, and reusability under the applied conditions.

Polyoxometalate Ionic Liquids as Self-Repairing Acid-Resistant Corrosion Protection

by Sven Herrmann, Monika Kostrzewa, Andreas Wierschem, Carsten Streb

Abstract

Corrosion is a global problem for any metallic structure or material. Herein we show how metals can easily be protected against acid corrosion using hydrophobic polyoxometalate-based ionic liquids (POM-ILs). Copper metal disks were coated with room-temperature POM-ILs composed of transition-metal functionalized Keggin anions [SiW11O39TM(H2O)]n (TM=CuII, FeIII) and quaternary alkylammonium cations (CnH2 n+1)4N+ (n=7–8). The corrosion resistance against acetic acid vapors and simulated “acid rain” was significantly improved compared with commercial ionic liquids or solid polyoxometalate coatings. Mechanical damage to the POM-IL coating is self-repaired in less than one minute with full retention of the acid protection properties. The coating can easily be removed and recovered by rinsing with organic solvents.

This corrosion: Hydrophobic polyoxometalate-based ionic liquids (POM-ILs) are used as temporary acid-resistant coatings for copper metal. Complete protection against acid vapors and liquid acids is observed and the POM-IL coating can withstand mechanical damage by a self-repairing mechanism. The compounds are easily removed and recovered for subsequent usage.

The Badlands are a type of parched, sunbaked terrain characterized by jagged rock, cracked earth and, of course, minimal vegetation. It’s a harsh environment of lifeless wasteland but there is also good news to be found in the badlands. For the patient observer, like photographer Guy Tal, there is a delicate beauty that reveals itself only so often. “On rare years,” says Tal, describing his series of photos taken in the American West, “wildflowers burst into stunning display of color, transforming the desert into a veritable garden for just few precious days.” The reason, apparently, is that vegetation in the region has adapted to the climate. With just a tiny bit of moisture the desert can transform into a colorful garden of bright purple and yellow. You can see more photos on Tal’s website, or purchase his book More Than a Rock.

We have used the hydrolysis of succinic anhydride to adjust the pH of peptide bolaamphiphile to form hydrogel, which is used as a template for in situ synthesis of Pd nanoparticles. The Pd nanoparticles are decorated on the surface of peptide nanofibers, which enhance the catalytic activity for C-C coupling reactions.
