Synthesis and Reactivity of a New Sterically-demanding Bis(thione) Ligand available in PDF, EPUB and Kindle. The coordination chemistry of the bis(mercaptoimidazolyl)xylenes (BmxR), a family of neutral bis(thione) ligands, has been extended. A novel, sterically-demanding ligand, ortho-bis(2-mercapto-l-tert-butylimidazolyl)xylene (o-BrnxtBu), has been successfully synthesized and characterized. The presence of a rigid xylylene backbone and a bulkier substituent lends an extended directionality and a pronounced steric effect to the ligand system. The coordination chemistry of the ligand system was explored with both transition (Re, Co, Cu, Ag, Au) and main group metals (Cd, Hg, In, Pb, Bi) to assess the mode of binding, reactivity, solubility patterns and the steric effects exerted by the bulky tert-butyl substituent. Xenobiotic heavy metals like Cd(II), Hg(II) and Pb(II) have a high affinity for sulfur rich active sites. They bind strongly with the cysteine and methionine residues found in proteins, thereby disrupting the normal body functions. Coordination chemistry of o-BmxtBu with these heavy metal centers was carried out to understand and assess the exact mechanism of binding of these metals within the body. The data and the structures obtained with o-BrnxtBu will be compared and contrasted, whenever possible, with the bis(mercaptoimidazolyl)methanes BmmR (R = Me, But) and the o-BmxMe ligand.

Download and read online ebook Synthetic Coordination and Organometallic Chemistry write by Alexander D. Garnovskii. This book was released on 2003-04-25. Synthetic Coordination and Organometallic Chemistry available in PDF, EPUB and Kindle. This reference describes standard and nonstandard coordination modes of ligands in complexes, the intricacies of polyhedron-programmed and regioselective synthesis, and the controlled creation of coordination compounds such as molecular and hn-p-complexes, chelates, and homo- and hetero-nuclear compounds. It offers a clear and concise review of modern synthetic techniques of metal complexes as well as lesser known gas- and solid-phase synthesis, electrosynthesis, and microwave and ultrasonic treatment of the reaction system. The authors pay special attention to o-hydroxyazomethines and their S-, Se-containing analogues, b-diketones, and quinines, among others, and examine the immediate interaction of ligands and metal salts or carbonyls.

Download and read online ebook Metal Mediated Template Synthesis of Ligands write by Otilia Costisor. This book was released on 2004. Metal Mediated Template Synthesis of Ligands available in PDF, EPUB and Kindle. This book surveys the relatively new area of the synthesis of organic ligands when metal ions act as a template. In the last fifty years this field has undergone an explosive development, marked by a great amount of literature. The material in the book has been arranged according to the type of chemical reaction involved. In this frame, the basic principles of metal template reactions and the shape of the molecules are considered. Designed to satisfy the demands of students, young researchers doing their PhDs, and those working in the field of coordination chemistry, the book details the role of the metal ions and the specific properties of the formed complexes. Metal Mediated Template Synthesis of Ligands offers a comprehensive analysis with wide-ranging references and provides an extensive overview of research on metal-directed organic ligands over the past five decades. Contents: The Template Effect; Alkylation Reactions; Schiff Condensation; Mannich Condensation; Self Condensation of Nitriles; Self-Assembled Systems. Readership: Upper level undergraduates, graduate students, academics, researchers industrialists in inorganic, solid-state, supramolecular and organic chemistry.

Download and read online ebook Direct Synthesis of Coordination and Organometallic Compounds write by A.D. Garnovskii. This book was released on 1999-08-13. Direct Synthesis of Coordination and Organometallic Compounds available in PDF, EPUB and Kindle. This book is devoted to the interaction between elemental metals and (in)organic ligands in different reaction conditions. Metals could be activated for further reactions as cryosynthesis, electrosynthesis and tribosynthesis, some of them with or without ultrasonic and microwave treatment. The kinetics of metal dissolution in various non-aqueous media is discussed in detail. Many methods are used nowadays to synthesize coordination compounds. Metal complexes are obtained mainly by the direct interaction of the components (the ligands and a source of the complex-forming metal), as a result of ligand and metal exchange, and under the conditions of template synthesis, which also include the method of nascent reagents. In these methods the source of the metal is either its salts or carbonyls. At the same time, it has long been known that coordination compounds may be obtained as a result of direct synthesis from zero-valent metals. Methods for the synthesis of complex compounds under the conditions of gas-phase reactions, oxidative dissolution of zero-valent metals in non-aqueous media, and in the solid phase have been developed. These methods have become the basis of a new field in synthetic chemistry - the direct synthesis of coordination and organometallic compounds from zero-valent metals. Particular aspects of the above problem have been described in a series of reviews and monographs. However, on the whole these main parts of the direct synthesis of metal complexes has not been dealt with in the review and monograph publications on coordination chemistry. So, the main objective of this book is to analyze, discuss and generalize the existing information in the area of direct reactions leading to the coordination and organometallic reactions. Some methods of direct synthesis have been developed in the former USSR (in particular, a lot of works on cryosynthesis, pioneered (1972-1973) and recent works on electrosynthesis) but, in spite of their novelty and/or wide applicability, they are practically unknown elsewhere due to the language barrier. Thus, another objective of this book is to acquaint the readers with the mentioned achievements. Every chapter contains the tables which describe all the reported data on direct reaction between metal atoms, metal particles or bulk metals with (in)organic ligans. There are some illustrations also (for example, the scheme of the reactor for gas-phase reaction between metal small particles and &bgr;-diketones).
