This book was released on 1993 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: As metal ion play an important role in biological systems, many complexes with synthetic macrocyclic ligands have been prepared to serve as models for biologically important species [1]. The presence of nickel in the enzyme hydrogenases is an example of the catalytic role of metal ions in redox reactions [2] of biological importance. The selectivity of cyclic antibiotics towards cation has commercial applications. Extending earlier work [4,5], we have synthesized new macrocyclic complexes of nickel (II) and cooper(II);the macrocycles were prepared by condensing 2, 6-diacetylpyridine with pyridine-2, 6-dicarboxylic acid dihydrazide.

Available in PDF, EPUB and Kindle. Book excerpt: Synthetic Multidentate Macrocyclic Compounds attempts to bring together selected chapters in which the authors discuss in depth investigations in important areas of macrocycle research. The chapters deal mainly with macrocyclic compounds (saturated polyethers and their derivatives), and macrobicyclic compounds (cryptates). The book contains six chapters and opens with a first-hand account of the initial synthesis of the cyclic polyethers. This is followed by separate chapters on the synthesis of cyclic polyethers, polyether amines, and polyether sulfides; the synthesis of multidentate compounds; and the structure of synthetic macrocyclic compounds and their cation complexes. Subsequent chapters deal with the rates of reactions and the mechanism by which synthetic macrocyclic ligands complex substrates in solution; and commercial applications of the synthetic macrocyclic ligands. This book is primarily aimed at researchers and students in organic, physical, analytical, and inorganic chemistry, and in chemical engineering. However, it will also be of interest to many in the areas of biology, biochemistry, and physiology. Extensive literature references are found in each chapter.

This book was released on 1992 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the fundamental physical principles of the selective complexation, extraction, and transport of ions and molecules by macrocyclic compounds - both natural and synthetic. It also treats the use of these compounds for the extraction and transport of substrates in chemical and biological systems. Included are solution kinetic and thermodynamic properties of the complexes, along with relevant experimental methods, complemented by solution and solid-state structures. General and specific methods for the synthesis of macro(poly)cyclic specialised ligands are described. The book is useful as additional reading for undergraduate courses in chemistry (e.g. inorganic complexation chemistry, analytical chemistry, solution kinetics, synthesis) and biochemistry (ion transport/membrane phenomena); for graduate students in chemistry and biochemistry; for research workers in macrocyclic chemistry and biophysical chemistry; and for industrial laboratories involved in metal ion extraction and recovery.
Download or read book The Chemistry of Macrocyclic Ligand Complexes written by Leonard F. Lindoy and published by Cambridge University Press. This book was released on 1989-03-23 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains an overview of complex formation by macrocyclic ligand systems. The study of macrocyclic chemistry represents a major area of activity which impinges on a range of other areas in both chemistry and biochemistry. The field has characteristically yielded many interesting and unusual compounds. The text discusses the structures and properties of macrocyclic compounds; the synthesis of macrocycles; polyether crown and related systems; metal-ion and molecular recognition (host-guest chemistry); as well as kinetic, thermodynamic and electrochemical aspects of a range of macrocyclic systems. A discussion of the different categories of naturally occurring macrocycles is also included. Specialist and non-specialist alike will find this a useful text. Apart from serving as a convenient reference for established workers in the field, it should also prove useful to new graduate students as well as to researchers from other areas who seek a general introduction to the subject. The topics discussed also provide a suitable basis for a senior undergraduate or graduate course in macrocyclic chemistry and inorganic complexes.

Download or read book Synthesis Biological Studies of Macrocyclic Transition Metal Complexes written by Rayees Sheikh and published by LAP Lambert Academic Publishing. This book was released on 2012-07 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the important facts about the synthesis and biological studies of macrocyclic transition metal complexes. A detailed synthetic discussion of the reaction steps in each mechanism and their relationship with transition metal complexes has been considered. Macrocyclic ligands and their transition metal complexes depends upon the nature of reactants and the corresponding metal ion. The macrocyclic ligand are a growing class of compounds with varying chemistry a wide range of different molecular topologies and set of donor atoms. Aza type ligands appear as very promising to be used as antifertile, antibacterial, antifungal and other biological properties. Macrocyclic metal complexes play a central role in the construction of molecular materials, which display magnetic properties and find applications in material and supramolecular chemistry and biochemistry. It is believed that the present book will provide a succinct and clear introduction to synthesis, characterization and biological studies macrocyclic ligands with transition metal complexes that meets the needs of researchers at a variety of levels in several disciplines.
Download or read book Coordination Chemistry of Macrocyclic Compounds written by Gordon Melson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemists have been aware of the existence of coordination compounds con taining organic macrocyclic ligands since the first part of this century ; however, only during the past few years have they expanded research into the chemistry of these compounds. The expansion was initiated in the early 1960s by the synthesis and characterization of compounds containing some new macrocyclic ligands. The synthesis of compounds which may serve as model systems for some natural products containing large rings as ligands provided the main goal for the early expansion of research effort; indeed, a recurrent theme behind much of the reported chemistry has been the analogy between synthetic macrocyclic compounds and many natural-product systems. More recently, the emphases of reported research have ranged over the whole spectrum of chemistry, and the number of publications that discuss macrocyclic chemistry has increased at a dramatic rate. The completed research has been reported in a variety of journals throughout the world but there has been no previous attempt to bring the major developments together under one cover. This book, therefore, attempts to satisfy the need for a single source in which there is both a collection and a correlation of information concerning the coordination chemistry of macrocyclic compounds. The chapters in this book discuss various aspects of macrocyclic chemistry, and while these chapters as a whole constitute an in-depth survey of the state-of the-art of the field, each chapter is written as a complete unit.
