Stereochemical And Stereophysical Behaviour Of Macrocycles

Stereochemical and Stereophysical Behavior of Macrocycles deals with the stereochemical and stereophysical properties of macrocyclic ligands and their coordination compounds. More specifically, the stereochemistry of metallic macrocyclics is discussed, along with the relationship between the thermodynamics and stereochemistry of macrocyclics and cryptates. The stereochemical aspects of the macrocycles of second and third row transition elements are also examined. Comprised of three chapters, this volume begins with an introduction to the stereochemistry of metallic macrocyclics as well as their structure, together with the conformation of their chemical rings and the steric effects of their coordination geometry. The next chapter considers the relationship between the thermodynamics and stereochemistry of macrocyclics and cryptates, with particular reference to the macrocyclic and cryptate effect. Cation-ligand interactions and solvent effects upon complex formation are described, along with macrocyclic and macrobicyclic ligands having different donor atoms. The final chapter is devoted to the stereochemical aspects of the macrocycles of transition metal ions, with additional comments on the stereochemistry of copper and nickel in unusual oxidation states. This book will be of interest to inorganic chemists.

This well-illustrated and well-referenced book provides a systematic introduction to the modern aspects of the topographical stereochemistry of coordination compounds, which are made up of metal ions surrounded by other non-metal atoms, ions and molecules.

Since the discovery of crown ethers by Pedersen in 1967, several thousands of crown ethers and analogous compounds have been synthesized. Their specific characteristics have been investigated and a variety of applications developed. These developments have led to new fields of chemistry called host-guest chemistry and supramolecular chemistry. This book presents the state-of-the-art of the chemistry of crown ethers and analogous compounds. The first chapter provides an orientation in the new fields of chemistry. Chapter 2 reviews advances in synthetic procedures for crown ethers and analogous compounds including azacrown ethers, thiacrown ethers, functionalized crown ethers, cryptands and others. The focus of chapter 3 is on the concept and synthetic strategies for the molecular design of new crown compounds. Chapters 4-7 are concerned with noteworthy topics in the applications of crown compounds. Chapter 4 deals with the application to ion-selective electrodes and liquid chromatography, both of which are the most important targets in the analytical application of crown compounds. One major application of crown ethers is the design and syntheses of artificial molecules which can catalyze a useful synthetic reaction in an enzyme-mimetic reaction manner, through novel non-covalent complexes. The strategies for enzymatic modelling with crown ethers are covered in chapter 5, while chapter 6 presents the principle of amine-selective colour complexation and its application. In chapter 7 switched-on crown ethers that can respond to environmental stimuli are reviewed. The final chapter is devoted to a wide-ranging discussion of developments in macrocyclic polyamine chemistry. Unlike crown ethers, macrocyclic polyamines, bearing nitrogen donor atoms which belong to a soft base, form complexes with ions of transition metals and heavy metals which are classified as soft acids. Therefore, macrocyclic polyamines are expected to have very versatile applications. Scientists in chemistry, biochemistry, physical organic chemistry, pharmaceutical chemistry and industrial chemistry will find this book a helpful summary and a stimulating contribution to research in this specialized field of crown compounds.

Almost all branches of chemistry and material science now interface with organometallic chemistry-the study of compounds containing carbon-metal bonds. Organometallic compounds range from species which are so reactive that they only have a transient existence at ambient temperatures to species which are thermally very stable. This widely acclaimed serial contains authoritative reviews that address all aspects of organometallic chemistry, a field which has expanded enormously since the publication of Volume 1 in 1964.

Calixarene chemistry, at the turn of the millennium, is a field approaching true maturity.

This book describes the coordination chemistry of macrocyclic ligands. Common types of ligands are introduced and strategies for the synthesis of the free ligands and their metal complexes are discussed. The unique thermodynamic and kinetic properties of macrocyclic complexes are introduced and applications of the ligands presented. The book is suitable for advanced undergraduate or graduate students and assumes a knowledge of organic and inorganic chemistry at the second year undergraduate level.
