Download or read book The Age of Noninnocence written by Seth N. Brown and published by Wiley. This book was released on 2017-01-24 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive introduction to the unique and fundamental features of redox-active ligands, the preparation and characterization of their coordination complexes, and finally the importance of this class of molecules to biology, catalysis and materials. The book aims to provide a broadly accessible introduction to the particular features and opportunities unique to redox-active ligands. It begins with an introduction to the intellectual challenges posed by redox-active ligands and descriptions of the types of ligands and complexes in which ligand-centered redox activity are commonly observed. Following this, the book is divided into two sections as follows: The first section focuses on electronic structure and bonding, which has historically dominated this field and continues to be actively researched. The spectroscopic and other physical measurements that have been used to elucidate the electronic structure of these compounds are described. The interplay between synthesis, bonding models, and physical measurements has often been critical in shaping our understanding of these compounds. This interplay is illustrated by a number of case studies. The second section focuses on the use of redox-active complexes in stoichiometric and catalytic reactions. The scope of known reactions is presented, including examples from bioinorganic chemistry (both enzymes and model compounds). Where possible, the significance of the redox-active ligand is discussed, with an eye both to summarizing existing knowledge and pointing out possibilities for future research. This book explains the underpinnings of physical and theoretical techniques of redox-active ligands, providing up to date information on definitions, scope and applications for research scientists and graduate students working in organic and inorganic chemistry, organometallics and coordination chemistry.

Download or read book Spin States in Biochemistry and Inorganic Chemistry written by Marcel Swart and published by John Wiley & Sons. This book was released on 2015-09-17 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has long been recognized that metal spin states play a central role in the reactivity of important biomolecules, in industrial catalysis and in spin crossover compounds. As the fields of inorganic chemistry and catalysis move towards the use of cheap, non-toxic first row transition metals, it is essential to understand the important role of spin states in influencing molecular structure, bonding and reactivity. Spin States in Biochemistry and Inorganic Chemistry provides a complete picture on the importance of spin states for reactivity in biochemistry and inorganic chemistry, presenting both theoretical and experimental perspectives. The successes and pitfalls of theoretical methods such as DFT, ligand-field theory and coupled cluster theory are discussed, and these methods are applied in studies throughout the book. Important spectroscopic techniques to determine spin states in transition metal complexes and proteins are explained, and the use of NMR for the analysis of spin densities is described. Topics covered include: DFT and ab initio wavefunction approaches to spin states Experimental techniques for determining spin states Molecular discovery in spin crossover Multiple spin state scenarios in organometallic reactivity and gas phase reactions Transition-metal complexes involving redox non-innocent ligands Polynuclear iron sulfur clusters Molecular magnetism NMR analysis of spin densities This book is a valuable reference for researchers working in bioinorganic and inorganic chemistry, computational chemistry, organometallic chemistry, catalysis, spin-crossover materials, materials science, biophysics and pharmaceutical chemistry.

Download or read book Synthesis, Characterization and Applications of Complexes Involving Redox-active Ligands written by Romain Kunert and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We developed a new type of redox-active ligand, involving two N-heterocyclic carbenes and two phenolate units. The strong electron donating properties of the NHC moieties were utilized to stabilize complexes in high oxidation states while the phenolate groups were used as redox-active units. Group 10 metal complexes were developed. Their oxidation chemistry showed the formation of phenoxyl radicals, reaching up to two-electron oxidized, bis(phenoxyl) complexes. We also report the first Ni(III) complex with NHC donors. The ligand was also used to develop metal complexes with nitride ligands. The nitridomanganese complex proved to be unstable and degraded in successive intramolecular nitride-NHC reductive couplings. The degradation afforded a peculiar organic salt with three fused rings forming a central triazone pattern. Conversely, the chromium nitride complex could be isolated and thoroughly characterized. The one-electron oxidized product was generated reversibly at low temperature but readily evolved at room temperature. In a parallel work, we also developed new types of sterically hindered salen ligands to form distorted copper salen complexes as molecular models of galactose oxidase. The copper salen catalysts showed to be effective for the aerobic oxidation of non-activated alcohol substrates.

Book Synopsis An Investigation of Redox-active Isoindoline-based Ligands and Their Coordination Complexes by : Edwin Wing Yip Wong
Download or read book An Investigation of Redox-active Isoindoline-based Ligands and Their Coordination Complexes written by Edwin Wing Yip Wong and published by . This book was released on 2012 with total page 610 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structural and electronic properties of metal complexes with isoindoline-based redox-active ligands and the ability of these ligands to stabilize unusual oxidation states was investigated. Two types of redox-active ligands were examined: phthalocyanines (Pc) and bis(2-pyridylimino)isoindolines also known as lobsterates (Lb). In contrast to the ancillary or spectator ligands more commonly used in coordination chemistry, redox-active ligands can exist in a range of oxidation states. Additionally, the chemical inertness of the Pc ligand could be used to develop new catalysts where the Pc ligand can stabilize a highly reactive metal centre and also act as an electron reservoir in a catalytic cycle. With this in mind, the reduction of trichloro(phthalocyanato)niobium(V) was performed with various reducing agents in order to study the bond activating ability of the reduced species and to determine the crystal structure of the reduced products. C-O bond activation of ether-type solvents suggests that the Pc ligand is able to withstand bond activation from a highly reduced niobium centre while, at the same time, allowing the niobium centre to activate the C-O bonds of the solvent. NbPc complexes containing Pc(4-) ligands were structurally characterized. A reduced MgPc complex containing a Pc(3-) ligand was also structurally characterized. A report of gold(II) Pc and the ability of Pc to stabilize gold in an unusual, paramagnetic +2 oxidation state was re-investigated. Attempts to synthesize soluble versions of AuPc as well as the original AuPc did not produce the desired gold(II) products and only diamagnetic gold(III) Pcs were obtained. An unprecedented, ring- contracted gold(III) Pc analogue was discovered and structurally characterized in the process of these studies. A series of three new 5,6-substituted Lb ligands were synthesized and the redox properties of these ligands in copper(II) acetate complexes were evaluated using cyclic voltammetry. The reductions of the copper acetate Lb complexes were not chemically reversible. The 2,6-diisopropylphenoxy-substituted Lb copper acetate complexes formed acetate-bridged 1-D chains. Superconducting quantum interference device magnetometry suggests that the Cu centres are very weakly antiferromagnetically coupled.
