Book Description
To meet the search for new therapeutic compounds this book summarises the research on biologically active organic molecules (chapters 1, 2 and 3), metal complexes with biological activity (chapter 4), and shows the possibilities for co-ordination chemistry in the planning of metal complexes with interesting properties for application (chapters 5, 6, 7, 8, and 9). It should be remembered that in the design of a new potentially active metallodrug, beyond the nature of the metal, the choice of appropriate ligands which affect the thermodynamic and kinetic stability, as well as the solubility and lipophilicity of the complexes is of paramount importance. The information contained in the book concerns: 1) the interactions involving the members of the Nuclear Receptor superfamily and their ligands; 2) the role of chemokine ligands and their receptors in normal and disease processes, and the emerging therapeutic approaches of using chemokine antagonists for appropriately targeted therapy; 3) the inhibition of alkaline phosphatases by calix[4]arenes functionalysed at the macrocyclic upper rim by one or two methylenebisphosphonic acid fragments; 4) the main biological applications, enzyme modelling and antiproliferative and antimicrobial activity of such scorpionate-type complexes, which are classified by ligand and also by transition metal; 5) the silver(I) discrete and polymeric coordination compounds bearing 1,3,5-triaza-7-phosphaadamantane or its derivatives towards engineering functional silver-organic frameworks (MOFs); 6) arylhydrazones of methylene active nitriles and their use as starting materials for the generation of new organic and coordination compounds; 7) amidophosphate ligands as promising sensitisers of lanthanide ions emission; 8) N-acetylsalicylhydrazidate as a versatile ligand for the synthesis of higher nuclearity metal complexes, which are illustrated herein along with their applications; 9) the chemistry and some applications of formazans which can be used for the simultaneous selective determination of several metal cations. All chapters were compiled by renowned scientists, providing both beginners in the field and advanced researchers with comprehensive information on the subject.

Book Description
Many new drugs on the market are chiral compounds, that is, they can exist in two non-superimposable mirror-image forms. Asymmetric catalysis encompasses a large variety of processes for obtaining such compounds. The performance of the catalyst in those processes largely depends on the ligand that makes up the catalyst. This book describes the most relevant ligand libraries for some key processes, including an overview of the state of art and the key mechanistic aspects that favor a high catalytic performance. Key Features: The book presents historical content from the time of discovery for each family of ligands. Provides a description of the synthetic route and the ligand library's application in various catalytic asymmetric reactions Suitable as supplementary reading for courses targeting the design, synthesis and application of chiral catalysts, asymmetric catalysis and sustainable production Edited by a distinguished scientist in the field, the book has a diverse audience including research groups in homogeneous catalysis, particularly asymmetric transformations

Book Description
Clathrochelates are compounds which contain a metal ion encapsulated within a three dimensional cage of macrobicyclic ligand atoms. Within this cage the metal has unique properties and is to a great extent isolated from environmental factors. Such complexes are suitable as models of the most essential biological systems, membrane transport, electron carriers, highly selective and sensitive analytical reagents, catalysts for photochemical and redox processes, cation and anion receptors, etc. The aim of this monograph is to generalize and analyze experimental and theoretical data on clathrochelates in order to promote further research in this promising field of chemistry.Chapter 1 gives general concepts of complexes with encapsulated metal ions, discusses basic specific features of these compounds, considers and characterizes the main types of compounds with encapsulated metal ions and the main classes of clathrochelates, and includes the current nomenclature. Chapter 2 deals with the pathways of clathrochelate synthesis and the general procedures for the synthesis of macrobicyclic tris-dioximates, phosphorus-containing tris-diiminates, sepulchrates, sarcophagi-nates, and polyene and other types of clathrochelate complexes. Chapter 3 concerns studies of the electronic and spatial structure of clathrochelate complexes. In Chapter 4, the kinetics and mechanism of synthesis and decomposition reactions of macrobicyclic tris-dioximates, sarcophaginates, and sepulchrates in solution and gas phases are discussed. Chapter 5 considers the electrochemical, photochemical, and some other characteristics of clathrochelates and their applications associated with these characteristics. Finally, the practical applications of the unique properties of clathrochelates and perspectives on the synthesis of new clathrochelates are described in Chapters 6 and 7, respectively.

Book Description
This book explores the development of the first open-shell heavier tetrylidyne complexes featuring a tetrel-centered unpaired electron, and unprecedented metallatetrylidynes containing a multiply-bonded, linear-coordinated single heavier tetrel atom embedded between two metal centers. The chemistry of compounds featuring triple bonds of the heavier Group-14 elements Si–Pb with transition metals is a very challenging research area, which combines modern molecular main-group element with transition-metal chemistry, and is of fundamental importance for the understanding of chemical bonding. During the last 15 years, the research in this area has witnessed considerable progress in isolating a series of closed-shell tetrylidyne complexes. However, despite numerous attempts, open-shell tetrylidyne complexes and heavier group 14 element congeners of metallacarbynes and carbide complexes remained inaccessible. In this book, readers will find more about the synthesis, full characterization and reactivity studies of these novel complexes that uncovered a plethora of exceptional products, including a novel m3-silicido complex, the first dimetallasilacumulene with a linear, two-coordinated single silicon atom and the first compounds of planar tetracoordinated silicon (ptSi) (Anti-van’t Hoff-Le Bell Silicon). Readers will also learn about the isolation and full characterization of the first room-temperature stable disilavinylidene, a silicon analogue of the very reactive vinylidenes (R2C=C:), and the first intermetallic plumbylidyne ligand transfer reactions.

Book Description
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.
