In the last decade there have been numerous advances in the area of rhodium-catalyzed hydroformylation, such as highly selective catalysts of industrial importance, new insights into mechanisms of the reaction, very selective asymmetric catalysts, in situ characterization and application to organic synthesis. The views on hydroformylation which still prevail in the current textbooks have become obsolete in several respects. Therefore, it was felt timely to collect these advances in a book. The book contains a series of chapters discussing several rhodium systems arranged according to ligand type, including asymmetric ligands, a chapter on applications in organic chemistry, a chapter on modern processes and separations, and a chapter on catalyst preparation and laboratory techniques. This book concentrates on highlights, rather than a concise review mentioning all articles in just one line. The book aims at an audience of advanced students, experts in the field, and scientists from related fields. The didactic approach also makes it useful as a guide for an advanced course.

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.

Due to their distinctive properties, ionic liquids have attracted the great and unflagging interest of researchers for over 30 years. This interest has been focused mainly on their use as a green alternative to volatile organic solvents. However, they often act not only as solvents but also as catalysts, catalyst immobilizers and initiators. Over 100 types of chemical reactions are known in which ionic liquids (ILs) were applied successfully. This Special Issue is aimed at showing the most recent advances and trends in the design, synthesis and characterization of catalysts based on ILs, as well as presenting their activity and application potential.
