The series Topics in Organometallic Chemistry presents critical overviews of research results in organometallic chemistry. As our understanding of organometallic structure, properties and mechanisms increases, new ways are opened for the design of organometallic compounds and reactions tailored to the needs of such diverse areas as organic synthesis, medical research, biology and materials science. Thus the scope of coverage includes a broad range of topics of pure and applied organometallic chemistry, where new breakthroughs are being achieved that are of significance to a larger scientific audience. The individual volumes of Topics in Organometallic Chemistry are thematic. Review articles are generally invited by the volume editors. All chapters from Topics in Organometallic Chemistry are published OnlineFirst with an individual DOI. In references, Topics in Organometallic Chemistry is abbrev iated as Top Organomet Chem and cited as a journal.

This book describes the emergence and recent advances in the design and development of rhodium complexes as therapeutic agents. Different classes of anticancer rhodium complexes with particular emphasis on ligands containing nitrogen-oxygen donor atoms are presented. Anticancer rhodium complexes of N-heterocyclic carbenes are described, while half-sandwich, heterobimetallic, and multinuclear rhodium complexes are discussed. Therapeutic applications of rhodium complexes beyond cancer such as antibacterial agents or antiviral agents are also analyzed, among others. Their mechanism of action is overviewed in detail, and the authors thoroughly comment on the challenges and future outlooks of research in the development of rhodium metallodrugs. This title highlights the important research carried out in the development of therapeutic rhodium complexes and is of great interest to graduates and researchers working in the area of rhodium-based therapeutic drugs.

Kinetics and reactor modeling for heterogeneous catalytic reactions are prominent tools for investigating and understanding catalyst functionalities at nanoscale and the related rates of complex reaction networks. This book illustrates some examples related to the transformation of simple to more complex feedstocks, including different types of reactor designs, i.e., steady-state, transient plug flow reactors, and TAP reactors for which there is sometimes a strong gap in the operating conditions from ultra-high-vacuum to high-pressure conditions. In conjunction, new methodologies have emerged, giving rise to more robust microkinetics models. As exemplified, they include the kinetics and the dynamics of the reactors and span a large range of length and time scales. The objective of this Special Issue is to provide contributions that can illustrate recent advances and novel methodologies for elucidating the kinetics of heterogeneous reactions and the necessary multiscale approach for optimizing the reactor design. This book is dedicated to postgraduate and scientific researchers, and experts in heterogeneous catalysis. It may also serve as a source of original information for the elaboration of lessons on catalysis for Master students.

This Special Issue on “Catalysts for Syngas Production”, included in the Catalysts open access journal, shows new research about the development of catalysts and catalytic routes for syngas production, and the optimization of the reaction conditions for the process. This issue includes ten articles about the different innovative processes for syngas production. Synthesis gas (or syngas) is a mixture of hydrogen and carbon monoxide, with different chemical composition and H2/CO molar ratios, depending on the feedstock and production technology used. Syngas may be obtained from alternative sources to oil, such as natural gas, coal, biomass, organic wastes, etc. Syngas is a very good intermediate for the production of high value compounds at the industrial scale, such as hydrogen, methanol, liquid fuels, and a wide range of chemicals. Accordingly, efforts should be made on the co-feeding of CO2 with syngas, as an alternative for reducing greenhouse gas emissions. In addition, more syngas will be required in the near future, in order to satisfy the demand for synfuels and high value chemicals.
