This volume covers recent advances in the chemistry of ylidic compounds with focus on their application in the design of ligands with unique donor properties, the development of novel organic transformations as well as the use of ylides in homogenous catalysis. Thereby, this volume particularly aims at the community of organic and organometallic chemists engaged in synthetic chemistry and catalysis as well as in the use of special ligands for the stabilization of unusual main group element species and the “transition-metal free” activation of element-element/hydrogen bonds. These fields of research are highly active and vivid research areas to which ylide chemistry has only recently started to contribute, but has already led to fascinating developments in most different directions. This volume highlights these recent developments, thus giving not only an overview over the past achievements, but also possibilities for future applications. To this end, the chapters selected in this volume combine different aspects of ylide chemistry, starting with theoretical aspects in ligand design followed by synthetic organic methods, catalytic transformations and complex chemistry.

This much-needed resource brings together a wealth of procedures for the synthesis and practical use of diazocarbonyl compounds. It features methods for the preparation of important catalysts and for applications of diazocarbonyl compounds within each of the main transformation categories-including in-depth coverage of cyclopropanation, C-H and X-H insertion, Wolff rearrangement, ylide formation, aromatic cycloaddition and substitution, and many other useful reactions. Written by leading experts in the field, this book contains cutting-edge material on highly enantioselective transformations, and presents new ways of thinking about diazocarbonyl compounds and their applications, from donor-acceptor cyclopropanes in organic synthesis to macrocyclic cyclopropanation. Complete with illustrative examples of procedures in each chapter, clear diagrams, and a detailed bibliography, this practical reference gives readers the tools they need to put diazocarbonyl compounds to work for their own projects-an invaluable source of guidance for synthetic organic chemists, chemical scientists, and advanced students.
The second edition of this classic reference work has been completely revised and updated, as well as being enlarged by 20% to reflect the latest developments in synthetic organic fluorine chemistry, taking into account new applications in materials science and medicinal chemistry. The new developments in transition-metal-catalyzed methods for the introduction of fluorine and fluorinated groups are discussed. In addition, new chapters have been added on such important applications as organic electronics (OLEDs) and fluorinated dyes. Appendices containing synthetic procedures and conversions round off this comprehensive work. This work is a valuable reference for fluorine chemists that also provides nonspecialists with an introduction to the field. From reviews of the first edition: ''... a well-produced book with attractive graphics, photos and schemes. Throughout the book, coloured electrostatic maps of small organofluorine compounds are used toillustrate charge distributions. These are effective as well as attractive. I would point any organic chemist to this book who wants to learn about and do some fluorine chemistry. It provides uncluttered descriptions and a clear orientation to the literature in this important area of the organic chemistry.'' CHEMBIOCHEM - A European Journal of Chemical Biology

In the vast landscape of organic chemistry, sulfur-containing compounds play a pivotal role in pharmaceuticals, industrial processes, and a wide range of chemical transformations, where they often enable selective and otherwise challenging functionalization reactions. This primer aims not only to elucidate the fundamental characteristics of sulfoxides and sulfur ylides but also to address key challenges encountered in their chemistry. By examining the influence of molecular structure on reactivity, the authors uncover valuable insights that underpin the utilization of these compounds. The Versatile Organic Chemistry of Sulfur(IV) is conceived as a precursor to our more extensive review, tailored to provide foundational knowledge for readers seeking entry into the more specialized material presented therein. The authors‘ goal for this primer is to equip both novices and seasoned practitioners with an understanding that transcends theoretical concepts, fostering an environment ripe for exploration and innovation.
Chemists from Europe, North America, Japan, and India not only describe the chemistry of the three reactive intermediates relevant to their use in synthesizing complex organic compounds, they also provide detailed protocols of methods for generating and using them in reactions. About a third of the book is devoted to nitrogen, oxygen, and sulfur ylides. The rest ammonium, oxonium, and sulfonium; azomethine, carbonyl, and thiocarbonyl; and nitrile flavors.
