Available in PDF, EPUB and Kindle. Book excerpt: Given the nature of the work undertaken in this project, this thesis will be divided into six chapters. The topics discussed within this thesis primarily focus on the study of chiral bimetallic complexes both from a synthetic and a structural approach. The chemistry of magnesiate complexes will be covered in Chapters 1-3. Chapter 1 focuses on the synthesis and characterisation of five different adducts of the synthetically important lithium tris(n-butyl)magnesiate LiMg(nBu)3 (1). Complex 1 has been co-complexed with different ligands to form the complexes [(TMPDA)·Li(u-nBu)2Mg(u-nBu)]2 (48), [(PMDETA)·Li(u-nBu)(nBu)Mg(u-nBu)]2 (49) [{(R,R)-TMCDA}·Li(u-nBu)2Mg(u-nBu)]2 (51), [(TMEDA)·Li(u-nBu)(u-OnBu)Mg(nBu)]2 (52) and [[(dioxane)·Li(u-nBu)2Mg(u-nBu)]2]∞ (56) In Chapter 2, the reactivity of lithium magnesiates complexes for the asymmetric deprotonation of prochiral ketones is studied. Homoleptic and heteroleptic lithium magnesiate bases have been evaluated and the results highlight that good conversions and enantioselectivities can be achieved when lithium amide LiPEA (lithium (+)-bis-(R)-1-phenylethylamide, Li-57) and a second organometallic reagent are combined. The chemistry of chiral sodium magnesiates is studied in Chapter 3. Solid state and solution structural studies of complexes [NaMg(PEA)2nBu]∞ (103), [TMEDA·Na(PEA)2MgnBu] (104) and inverse crown ether [NaMg(PEA)4O] (105) have been performed. Compounds 103 and 104 have also been tested as deprotonating reagents towards 4-tert-butylcyclohexanone. Chapter 4 focuses on the synthesis of chiral homoleptic and heteroleptic lithium zincates and their applications in enantioselective addition reactions towards ketones. Two new lithium zincates have been fully characterised, TMEDA·Li(u-PEA)(u-Me)ZnMe (147) and (R,R)-TMCDA·Li(u-Me)2ZnMe (149). The alkyl addition to ketones with this monomer is successful although the enantiomeric excess is relatively low. Chapter 5 describes the synthesis, characterization and reactivity studies of a series of mixed alkali-metal complexes: [LiNa(PEA)2]2 (168), [(THF)2LiNaPEA2] (169) and [LiK(PEA)2]2 (170). A preliminary study on the reactivity of these amides as initiators of the asymmetric rearrangement of epoxides has been performed. Each chapter contains a self-contained experimental section where the synthesis and solution characterisation of the complexes are included. Chapter 6 summarises the synthetic procedures for starting materials, as well as a description of general experimental techniques. Finally, an appendix with the crystallographic data for compounds synthesised in this work is included after Chapter 6.

Book Synopsis S-Block Metal Complexes by : Matthias Westerhausen
Download or read book S-Block Metal Complexes written by Matthias Westerhausen and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation Dear Colleagues, The coordination chemistry of the s-block metals spans diverse fields, ranging from shielded coordination compounds over hydride to organometallic complexes for diverse applications. New developments pertain, not only to the lithium and magnesium chemistry with inspiring examples, such as heterobimetallic or heteroleptic complexes with special reactivity patterns, but the heavy s-block metals have progressively gained attention in various fields. Subvalent magnesium(I) derivatives are increasingly being used for reduction reactions, turbo-Grignard reagents show enhanced reactivity and tolerance toward functional groups, hydrides act as hydrogen storage materials, heavy Grignard reagents are available by straight forward procedures--just to name a few examples. Quantum chemical calculations deal with unique bonding situations and the relevance of d-orbital participation has been discussed to understand structure-reactivity relationships. Especially the complexes of the heavy alkaline earth metals are catalytically active in diverse reactions, promoting hydrofunctionalization reactions and Lewis acid catalysis. This Special Issue aims to highlight the structural and chemical diversity of s-block metal complexes, as well as the broad field of applications. Prof. Dr. Matthias Westerhausen Guest Editor.
Book Synopsis Introduction to Coordination Chemistry by : Geoffrey A. Lawrance
Download or read book Introduction to Coordination Chemistry written by Geoffrey A. Lawrance and published by John Wiley & Sons. This book was released on 2013-03-15 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the heart of coordination chemistry lies the coordinate bond, in its simplest sense arising from donation of a pair of electrons from a donor atom to an empty orbital on a central metalloid or metal. Metals overwhelmingly exist as their cations, but these are rarely met ‘naked’ – they are clothed in an array of other atoms, molecules or ions that involve coordinate covalent bonds (hence the name coordination compounds). These metal ion complexes are ubiquitous in nature, and are central to an array of natural and synthetic reactions. Written in a highly readable, descriptive and accessible style Introduction to Coordination Chemistry describes properties of coordination compounds such as colour, magnetism and reactivity as well as the logic in their assembly and nomenclature. It is illustrated with many examples of the importance of coordination chemistry in real life, and includes extensive references and a bibliography. Introduction to Coordination Chemistry is a comprehensive and insightful discussion of one of the primary fields of study in Inorganic Chemistry for both undergraduate and non-specialist readers.
