Special Issue Information

Dear Colleagues,

This is the second edition of the Special Issue titled “Recent Applications of Metal Catalysts in Organic Synthesis”.

In recent decades, the development of original and efficient processes to perform the synthesis of renewable and/or affordable chemicals with widespread applications in industry has become a topic of great interest. Transition-metal catalysis has undoubtedly participated in this area, with the topic being awarded five Nobel Prizes in chemistry since the 1960s. These were awarded for (1) Ziegler−Natta polymerizations, (2) the development of the metathesis, (3) palladium-catalyzed cross coupling reactions, (4) chirality and asymmetric catalysis, and last year (5) the "click" copper catalyzed azide-alkyne cycloaddition. In fact, all these prompt advances have significantly changed our world, notably by broadening the uses of fossil fuels, but also by enabling the discovery of many novel synthetic molecules and materials.

However, due to exponential population growth, the global energy crisis and the environmental burden, the need for the development of more efficient and environmentally friendly metal-based catalytic systems will become even more critical in the forthcoming decades.

In this context, this Special Issue aims to cover the most recent progresses and advances towards the design, synthesis, and characterization of novel metal catalysts, as well as their applications in environmental remediations and new routes for the production of molecules of biological, (photo)physical, agrochemical, and pharmaceutical interest.

Mixtures of ethanol and methanol being synthesized from CO2 and green H2 can serve as sustainable base chemicals for a number of chemical processes. Amongst these processes, the catalytically supported synthesis of CO2-neutral C4 to C10 alcohols is of increasing importance as, e.g., iso-butanol can be used as a drop-in fuel or after dehydration to produce iso-butene as a feedstock for the synthesis of plastics. 2-ethyl-hexanol can be further refined into solvents, tensides, or monomers. In this respect, NiPt alloys on an activated carbon support were found to be active and stable catalysts for the synthesis of iso-butanol following the Guerbet reaction scheme. In this study, two different routes are applied to the synthesis of these NiPt catalysts: a more conventional one based on the impregnation of Ni and Pt salts and an advanced path with a surface redox reaction between elemental Ni on the support and Pt ions in a polar solution. The experimental evaluation shows that the Pt particles from the surface redox reaction being exposed on the Ni particles are more active than those on the impregnated catalysts due to their high surface energy. Their specific space-time yields are 10–20 times higher. Full article
