Book Description
Written by experts in the field, this is a much-needed overview of the rapidly emerging field of cooperative catalysis. The authors focus on the design and development of novel high-performance catalysts for applications in organic synthesis (particularly asymmetric synthesis), covering a broad range of topics, from the latest progress in Lewis acid / Br?nsted base catalysis to e.g. metal-assisted organo catalysis, cooperative metal/enzyme catalysis, and cooperative catalysis in polymerization reactions and on solid surfaces. The chapters are classified according to the type of cooperating activating groups, and describe in detail the different strategies of cooperative activation, highlighting their respective advantages and pitfalls. As a result, readers will learn about the different concepts of cooperative catalysis, their corresponding modes of operation and their applications, thus helping to find a solution to a specific synthetic catalysis problem.

Book Description
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.

Book Description
The equations which we are going to study in these notes were first presented in 1963 by E. N. Lorenz. They define a three-dimensional system of ordinary differential equations that depends on three real positive parameters. As we vary the parameters, we change the behaviour of the flow determined by the equations. For some parameter values, numerically computed solutions of the equations oscillate, apparently forever, in the pseudo-random way we now call "chaotic"; this is the main reason for the immense amount of interest generated by the equations in the eighteen years since Lorenz first presented them. In addition, there are some parameter values for which we see "preturbulence", a phenomenon in which trajectories oscillate chaotically for long periods of time before finally settling down to stable stationary or stable periodic behaviour, others in which we see "intermittent chaos", where trajectories alternate be tween chaotic and apparently stable periodic behaviours, and yet others in which we see "noisy periodicity", where trajectories appear chaotic though they stay very close to a non-stable periodic orbit. Though the Lorenz equations were not much studied in the years be tween 1963 and 1975, the number of man, woman, and computer hours spent on them in recent years - since they came to the general attention of mathematicians and other researchers - must be truly immense.

Book Description
This volume looks at modern approaches to catalysis and reviews the extensive literature. Chapters highlight microkinetic modeling, encapsulated metals for confined catalysis, recent advances on the direct decomposition of NOx and heteropolyacid catalysts. There is also a chapter reviewing methods for estimating adsorption energies on catalytic surfaces, which will provide information from both fundamental and technological points of view. Appealing broadly to researchers in academia and industry, the detailed chapters bridge the gap from academic studies in the laboratory to practical applications in industry, not only for the catalysis field, but also for environmental protection. The book will be of great benefit to any researcher wanting a succinct reference on developments in this area now and looking to the future.

Book Description
The field of aromatic interactions, the fundamental nature of substituent effects and the identification of contacts between anions and aromatic systems have generated stimulating arguments in recent years. New theoretical frameworks have been developed and tested and aromatic interactions have emerged as potential solutions for varied problems in biology and materials science. This book provides a wide ranging survey of the latest findings and advances surrounding aromatic interactions, stretching from the fundamentals to modern applications in synthesis, biology and materials chemistry. It also discusses computational, experimental and analytical approaches to understanding these interactions, including pi-pi, anion-pi, and cation-pi interactions. Aromatic Interactions: Frontiers in Knowledge and Application is a useful text for advanced students and researchers, and appeals to those working within the fields of supramolecular chemistry, computational chemistry and thermodynamics.

Synthesis and Application of [2.2]Paracyclophane Derivatives in Catalysis and Material Science

Book Description
[2.2]Paracyclophane is a prevalent π‐stacked, carbocyclic scaffold with a “bent and battered” structure. This results not only in a transannular communication but also in a chiral plane within the molecule if at least one substituent is present. These unique properties make this structure synthetically challenging but also scarcely investigated. A new method for enantio-separation based on the kinetic resolution was developed, which allows the access to enantiomerically pure [2.2]paracyclophane-based building blocks. In a liquid crystal templated chemical vapor deposition process, [2.2]paracyclophanyl alcohols containing an additional central chiral element were evaluated for the self-assembly of nanofibers. Furthermore, the cyclopropanation of α-alkyl-α-diazo compounds with a [2.2]paracyclophane-based rhodium tetracarboxylate complex was investigated. Finally, the rigidity, regioselective functionalization, and transannular communication of [2.2]paracyclophane were exploited in the design of heterobimetallic gold/ruthenium complexes for the study of metal-to-metal interactions.

Book Description
After the overwhelming success of Asymmetric Synthesis - The Essentials, displaying a broad range of organic asymmetric syntheses, this is the second edition with latest subjects and authors. While the aim of the first edition was mainly to honor the achievements of the pioneers in asymmetric syntheses, the aim of this new edition was bringing the current developments, especially from younger colleagues, to the attention of students. The format of the book remained unchanged, i.e. short conceptual overviews by young leaders in their field including a short biography of the authors. The growing multidisciplinary research within chemistry is reflected in the selection of topics including metal catalysis, organocatalysis, physical organic chemistry, analytical chemistry, and its applications in total synthesis, materials research and industry. The prospective reader of this book is a graduate or undergraduate student of advanced organic chemistry as well as the industrial chemist who wants to get a brief update on the current developments in the field.
