Supramolecular Catalysis Provides a timely and detailed overview of the expanding field of supramolecular catalysis The subdiscpline of supramolecular catalysis has expanded in recent years, benefiting from the development of homogeneous catalysis and supramolecular chemistry. Supramolecular catalysis allows chemists to design custom-tailored metal and organic catalysts by devising non-covalent interactions between the various components of the reaction. Edited by two world-renowned researchers, Supramolecular Catalysis: New Directions and Developments summarizes the most significant developments in the dynamic, interdisciplinary field. Contributions from an international panel of more than forty experts address a broad range of topics covering both organic and metal catalysts, including emergent catalysis by self-replicating molecules, switchable catalysis using allosteric effects, supramolecular helical catalysts, and transition metal catalysis in confined spaces. This authoritative and up-to-date volume: Covers ligand-ligand interactions, assembled multi-component catalysts, ligand-substrate interactions, and supramolecular organocatalysis and non-classical interactions Presents recent work on supramolecular catalysis in water, supramolecular allosteric catalysis, and catalysis promoted by discrete cages, capsules, and other confined environments Highlights current research trends and discusses the future of supramolecular catalysis Includes full references and numerous figures, tables, and color illustrations Supramolecular Catalysis: New Directions and Developments is essential reading for catalytic chemists, complex chemists, biochemists, polymer chemists, spectroscopists, and chemists working with organometallics.

Hydrogen bonding has been widely observed in biosynthesis and enzyme catalysis. It plays an important role in such fields as molecular recognition, supramolecular chemistry and small molecule catalysis. A new concept of organocatalysis emerged in recent two decades. Hydrogen bonding is the keystone for thiourea catalysis or phosphoric acid catalysis. With high turnover numbers and excellent enantioselectivity, transition metal catalysis not only is the arts in academia, but also find its merit in industrial application. Homogeneous hydrogenation, among many successful transition metal catalyzed reactions, has been serving the synthetic communities for many years, both in academia or in industry. The success of secondary interaction and hydrogen bonding offer us an alternative: the combination of hydrogen bonding and steric hindrance help to create a chiral environment in which substrates could be reduced efficiently. Guided by this rationale, a ferrocene-based bisphosphine/thiourea ligand, ZhaoPhos was synthesized in our group. It was applied in the asymmetric hydrogenation of nitroolefins with hydrogen bonding between the ligand and substrates. Thiourea-carbonyl hydrogen bonding is another model of non-covalent interaction. Therefore, the asymmetric hydrogenation of unsaturated carbonyl compounds is also practical. Besides neutral compounds, ionic unsaturated substrates could form non-covalent interactions with thiourea through anion binding as well. It makes the asymmetric reduction of iminium ions and N-heteroaromatics (quinolines, isoquinolines and indoles) possible. These type of unsaturated compounds were challenging for traditional transition metal catalyzed hydrogenation. They could now be achieved with high enantioselectivity with a rhodium/ZhaoPhos complex. An outer-sphere mechanism involving hydride transfer was proposed since these substrates were thought to lack of coordinating ability to the metal center. As a traditional catalytic system, rhodium/bisphosphine complexes have been applied to catalyze hydrogenation of C=C bonds in a long time. The application in hydrogenation of non- or weak coordinating unsaturated compounds changed our view towards of this class of complexes. In the meanwhile, the role of hydrogen bonding is still a mechanistically unexplored area: what is the geometry of the ligand-substrate complex? How does the hydrogen bonding influence the activation energy in the transition state? Many in-depth studies are needed in the future.

A contemporary compilation of recent achievements in organometallic chemistry The prestigious International Conference on Organometallic Chemistry (ICOMC) was launched in 1963, providing a forum for researchers from around the world to share their findings and explore new paths to advance our knowledge and application of organometallic chemistry. The 25th ICOMC, held in Lisbon in 2012, gathered more than 1,200 participants from 54 countries. This volume celebrates the 25th Silver Edition and the 50th Gold Year of the ICOMC. Featuring contributions from invited 25th ICOMC speakers, Advances in Organometallic Chemistry and Catalysis highlights recent achievements and new and emerging areas of research in the field. Its seven sections cover: Activation and Functionalization of Carbon Single Bonds and Small Molecules Organometallic Synthesis and Catalysis Organometallic Polymerization Catalysis Organometallic Polymers and Materials Organometallic Chemistry and Sustainable Energy Bioorganometallic Chemistry Organometallic Electrochemistry Chapters discuss fundamental underlying concepts, offer illustrative examples and cases, and explore future avenues for continued research. Readers will discover basic principles and properties of organometallic compounds, reaction mechanisms, and detailed descriptions of current applications. Collectively, these chapters underscore the versatility, richness, and potential of modern organometallic chemistry, including its interrelationships with other scientific disciplines. All the contributions are extensively referenced, providing a gateway to the most important original research papers and reviews in organometallic chemistry. Presenting a contemporary understanding of organometallic chemistry and its many applications, Advances in Organometallic Chemistry and Catalysis is recommended for all researchers in the field, from students to advanced investigators.

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience.Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.The chapter "Enamine/Transition Metal Combined Catalysis: Catalytic Transformations Involving Organometallic Electrophilic Intermediates" is available open access under a CC BY 4.0 License via link.springer.com.
