Special Issue Information

Dear Colleagues,

To respond to the demand for more environmentally friendly chemical syntheses and processes, we can think, for example, of designing synthesis reactions with high atom economy or with minimal formation of secondary products. The use of catalysts can be advantageous to decrease the energy demand of a process, and the reduction of classic volatile and toxic organic solvents (VOCs) could be also a key point for the development of new environmentally friendly chemical processes. Furthermore, conducting the reactions in the absence of solvent or using non-conventional non-polluting solvents such as water, supercritical fluids, ionic liquids, and “deep eutectic solvents” (DESs) will increase the “greenness” of the syntheses. Particular attention is being paid to DESs which have raised increasing interest as a promising “green” alternative to VOCs for their unusual solvent properties in a variety of organic reactions as well as in process technology.

We invite the scientific community to submit their contributions as original research articles or review articles that describe new catalytic and biocatalytic processes, green synthesis, and known processes studied in conditions less harmful to the environment.

We are particularly interested in articles describing:

1) Synthetic methodologies in green solvents

2) Synthetic processes from renewable sources to valuable products

3) Bio-catalysis

4) Catalysts derived from natural sources

5) Chemical processes with reduced environmental impact: flow-chemistry, mechanochemistry

Abstract: Sustainable processes are key to solve the anthropogenic environmental issues. Homogeneous catalysis as a tool for such processes may provide one of the most powerful solutions. In particular, pincer complexes are an interesting class of catalysts that of recent has showed promising results by demonstrating improved activity, selectivity, and stability as well as specificity. A further advantage of this ligand class is the ease of variation for versatile tuning of the electronic and steric environment around the metal center. In the proposed review, we will review the recent progress in the use of pincer complexes as catalysts for sustainable reactions. These reactions include the following:
1) Acceptorless dehydrogenation: Hydrogen production from bioethanol, glycerol, carbohydrates, formic acid, etc, for H2 storage. Efficient biomass valorization, for example ethanol to sodium acetate or ethyl acetate, HMF to, for example, DFF or FDCA, etc
2) Hydrogenation: CO2 hydrogenation to formic acid or methanol, levulinic acid or alkyl levulinate to GVL, N2 fixation, etc
3) Transfer hydrogenation/hydrogen borrowing chemistry: ethanol upgrading to butanol, ethanol as H2 source, alcohol amination, etc
Note: Due to the facts that several reviews exist on the topic of pincer complexes, and that the progress within pincer complex catalyzed sustainable reactions is very impressive with many publications coming out each week, we will limit ourselves to the research conducted approximately the last five years.

Title: Montmorillonite K10-catalyzed Solvent-free Conversion of Furfural into Cyclopentenones

Abstract: A simple and eco-friendly Montmorillonite K10 catalyzed method for the synthesis of  cyclopentenone derivatives by biomass-produced furfural has been developed. The versatility of this protocol is that the reactions were performed in solvent free condition in short reaction time under heterogeneous catalysis condition. Montmorillonite K10 is a catalytic material most explored in heterogeneous catalysis because it is inexpensive and environmentally friendly.

Abstract: In this study a novel hydrolysis-hydrothermal method for simultaneous hydrogen production and rutile TiO2 synthesis was revealed. The rutile TiO2 was synthesized via hydrolysis-hydrothermal process. Firstly, the yield of hydrogen production via hydrolysis of MgH2 was studied while simultaneously TiO2 was synthesized. Titanium tetrachloride and MgH2 were used as raw materials. The amount of hydrogen released during the hydrolysis reaction was close to the theoretical value.  The synthesized TiO2 via hydrolysis-hydrothermal process contained only pure rutile phase. The produced rutile TiO2 was characterized with different techniques such as TEM, SEM and XRD and its photocatalytic activity was evaluated for degradation of a pharmaceutical pollutant.  In one hand magnesium is an abundant element in the earth's crust and which makes magnesium hydride as a promising hydride for hydrogen storage because of its low cost, ready availability, abundance and low toxicity. However high temperatures above 320℃ are needed to decompose MgH2 and release the hydrogen accumulated.  In contrast, hydrolysis reaction of MgH2 in water under the room temperature liberates only a small percentage of the theoretical amount of H2 due to the formation of Mg(OH)2. Here we simultaneously produce hydrogen and synthesize rutile TiO2 while we were successful to avoid passivation layer. This novel hydrolysis-hydrotermal method could be introduced to industries for double benefit on hydrogen and rutile TiO2 production.
