This book was released on 2012-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macrocyclic ligands that can incorporate two or more metal ions giving homo- or hetero-dinuclear complexes are of considerable interest. Some of these hetero-dinuclear complexes are interesting as they mimic the active sites of metalloenzymes, such as cytochrome-c oxidase and bovine erythrocyte superoxide dismutase. Such systems are very helpful in investigating mutual influences of the two metal centers on electronic, magnetic, and electrochemical properties. Therefore, such types of system are very helpful in biological diagnostic applications. Research in inorganic chemistry has expanded in recent years by exploiting a variety of chelating ligands to modify and control the characteristics of metal ions in biological systems. Macrocyclic ligands offer the benefit of high stability complex formation and, through functionalization, the opportunity to modify the coordination environment. The pharmaceutical and bio-medical industry has yet to appreciate the impact coordination chemistry can have on the design of novel medicines. This may change the future as skilled multi-disciplinary experts may develop their investigation using a strategic approach to complex design.

Book Synopsis Coordination Chemistry of Macrocyclic Compounds by : Gordon Melson
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.

Book Synopsis Synthetic Multidentate Macrocyclic Compounds by : Reed Izatt
Download or read book Synthetic Multidentate Macrocyclic Compounds written by Reed Izatt and published by Elsevier. This book was released on 2012-12-02 with total page 335 pages. 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.

Book Synopsis Biomimetic Carboxylate-bridged Diiron Complexes by : Mikael Antoine Minier
Download or read book Biomimetic Carboxylate-bridged Diiron Complexes written by Mikael Antoine Minier and published by . This book was released on 2015 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 1: Understanding the Utility of Hydrogen Bonding Donors in the Secondary Coordination Sphere of Non-heme Metal Complexes Chapter 1 is a mini-review that covers systematic studies on the effect of hydrogen bonding donors on the properties of metal complexes. Generalizing across different metals studied in biomimetic chemistry, the review allows for the comparison between different systems and generalizations are drawn about the effects of secondary coordination sphere hydrogen bond donors. Chapter 2: 19F NMR Study of Ligand Dynamics in Carboxylate-Bridged Diiron(II) Complexes Supported by a Macrocyclic Ligand A series of asymmetrically carboxylate-bridged diiron(II) complexes featuring fluorine atoms as NMR spectroscopic probes, [chemical formula ...] (10), [chemical formula ...] (11), and [chemical formula ...] (12) were prepared and characterized by X-ray crystallography, M6ssbauer spectroscopy, and VT 19F NMR spectroscopy. These complexes are part of a rare family of syn-N diiron(II) complexes, [chemical formula ...], that are structurally very similar to the active site of MMOHred. Solution characterization of these complexes demonstrates that they undergo intramolecular carboxylate rearrangements, or carboxylate shifts, a dynamic feature relevant to the reactivity of the diiron centers in bacterial multicomponent monooxygenases. Chapter 3: Structural Characterization of Carboxylate-Bridged and Hydroxo-Bridged Dizinc(II) Complexes Supported by a Macrocyclic Ligand Using a syn-N dinucleating macrocyclic ligand, H2PIM, a doubly carboxylate-bridged dizinc(II) complex, [chemical formula ...] (6) was prepared. In crystallizations of 6, two pseudoisomorphs of [chemical formula ...] (7) were discovered. On route to the synthesis of 6, a zinc complex, [chemical formula ...] (4) was prepared and the product upon reaction with air, [chemical formula ...] (5), was crystallized. Chapter 4: Secondary Coordination Sphere Modulation of Redox Potentials in Azide-Bridged Diiron(II) Complexes Observation that the H2PIM macrocyclic ligand provides an extra binding site for the binding of small molecules adjacent to corresponding diiron(II) complexes inspired the appendage of a secondary coordination sphere hydroxyl group to the ligand. The new ligand, H3PIM2, models not only the primary coordination sphere of the diiron sites of methane monooxygenase and toluene/o-xylene monooxygenase, but also that of a local threonine in the secondary coordination sphere. This chapter explores the differences between the PIM system and PIM2 system through the electrochemistry of the azido diiron(II) derviatives. Chapter 5: Synthesis and Characterization of a Linear Dinitrosyl-Triiron Complex Nitric oxide is released during the immune response by the host during bacterial infection. To counteract this response, bacteria have evolved nitric oxide reductases to convert NO to N2O. Some of these nitric oxide reductases contain a flavodiiron active site that have bridging carboxylates and hydroxides. Only a handful of synthetic complexes currently exist as models for the protein reactivity. Here we report the reaction of [chemical formula ...] (4) with NO(g) and Ph3CSNO to prepare the dinitrosyl-triiron complex [chemical formula ...] (5). The reaction was monitored by U V-Vis and ReactIR spectroscopy and compound 5 was characterized by X-ray crystallography, 5 7Fe M6ssbauer spectroscopy, Evans' method, and FTIR spectroscopy. The IR spectrum of compound 5 compares favorably to experimental spectroscopic data obtained for the proposed mononitrosylated intermediate of the protein. Chapter 6: Doubly and Triply Carboxylate Bridged Bis(ethylzinc) Complexes and Formation of the ([mu]-Oxo)tetrazinc Carboxylate [chemical formula ...] Ethylzinc 2,6-bis(p-tolyl)benzoate converts between two forms in solution. Through NMR spectroscopic techniques and X-ray crystallography, the species in equilibrium were identified as [chemical formula ...] (1), [chemical formula ...] (2), and diethyl zinc [chemical formula ...]. The equilibrium provides a model for understanding the speciation between doubly and triply m-terphenylcarboxylate-bridged diiron(II) and mononuclear iron(II) complexes. Evidence is presented for the occurrence of coordinatively unsaturated trigonal zinc species in solution. Both 1 and 2 decompose in air to form the T-symmetric oxozinc carboxylate, [chemical formula ...] (3). Appendix A: Synthesis and Characterization of Mononuclear, Pseudotetrahedral Cobalt(III) Compounds The preparation and characterization of two mononuclear cobalt(III) tropocoronand complexes, [chemical formula ...] and [chemical formula ...], are reported. The cobalt(III) centers exist in rare pseudotetrahedral conformations, with twist angles of 65° and 74° for the [Co(TC-5,5]+ and [Co(TC-6,6)]+ species, respectively. Structural and electrochemical characteristics are compared with those of newly synthesized [chemical formula ...] and [chemical formula ...] analogs. The spin state of the pseudotetrahedral [chemical formula ...] was determined to be S = 2, a change in spin state from the value of S = 1 that occurs in the square-planar and distorted square-planar complexes, [chemical formula ...] and [chemical formula ...], respectively. Appendix B: Synthetic Strategies toward Sterically Demanding Macrocyclic Ligands In order to prevent the formation of iron complexes of nuclearity higher than 2, a picket-fence macrocyclic ligand, H2tipp4PIM was designed. This chapter discusses the progress towards the synthesis of this ligand as well as design strategies.
