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.

Progress in Heterocyclic Chemistry Volume 5 deals critically with original material selected essentially from the 1992 heterocyclic literature. Chapters 1 and 2 are given over to reviews: in the first, SO2 extrusion from five-membered rings is discussed by R.A. Aitken and colleagues, which completes last year's review on this topic. The second review presents a review of 2-acylamino-3-dimethylaminopropenoates in heterocyclic synthesis. The chapters are arranged according to ring sizes as in the previous volumes and are supported by references, numerous diagrams and a subject index.

This volume dictionary brings together accurate chemical, structural and bibliographic data on the most commonly used reagents in the various branches of analytical chemistry. Covering both organic and inorganic compounds, the "Dictionary of Analytical Reagents" contains over 5,000 reagents significant in analytical chemistry, grouped into 5,000 entries. All the reagents included in the dictionary have been synthesized, characterized by or are of proven use to analytical chemists. Compiled by a distinguished board of leading figures in the world of analytical chemistry, each an expert in their own specialist field, the "Dictionary of Analytical Reagents" is a companion volume to the renowned "Dictionary of Organic Compounds" and follows a similar format. The dictionary is arranged in such a way as to facilitate browsing, with entries ordered alphabetically by entry name (often its trivial name). Clearly laid out in an easy-to-follow manner, each entry contains a wealth of data invaluable to the analytical chemist including synonyms, analytical applications, extensive and up-to-date hazard/toxicity data, solubility, dissociation constant and selected references labelled to indicate their content (e.g. analytical application, spectral data, synthesis). High quality structure diagrams are included to assist the analytical chemist in identifying the reagent needed and are drawn to standard orientations. Coverage extends to metal extractants, spectrophotometric reagents, indicators, fluorescence labelling reagents, resolving agents, nmr shift reagents and reference standards, buffers, gc and ms derivatisation reagents, amperometric reagents, titrimetric and gravimetric reagents, biological stains and dyes. Compounds are comprehensively indexed by Name, Molecular Formula, CAS Registry Number and Type of Compound. The unique Type of Compound Index is particularly valuable as compounds are indexed by use (eg NMR shift reagent), by analyte (eg nickel) and by compound group (eg formazan, crown ether), making the data accessible by a variety of criteria. Thus, chemists can use the dictionary to find information on how to analyze for a particular substance, how a particular compound may be used as an analytical reagent or what other reagents are available for a specific analytical use. Having located all appropriate reagents via the index, the user can then browse through the entries to obtain specific data, all fully referenced in the selective bibliography. Analytical chemists - be they in the manufacturing or pharmaceutical industry, working in hospital laboratories as clinical chemists or pollution analysts monitoring heavy metal residues in waste water - constantly need to make decisions about which reagent to choose for a particular application. This dictionary fulfils that need by being the most comprehensive, reliable and up-to-date compilation of reagents available. This book should be of interest to analytical chemists in academic and industrial establishments, forensic scientists, chromatographers, biochemists, standards institutions, companies selling laboratory chemicals, and water authorities.
