Book Description
This work culminates a systematic study of various uranium complexes supported by ferrocene diamide ligands. Chapter 1 reports the synthesis of 1,1'-ferrocene diamines and describes their electronic and steric properties in both neutral and oxidized forms. Chapter 2 describes an efficient synthesis of uranium dialkyl complexes supported by a single 1,1'- ferrocene diamide ligand, while Chapter 3 explores their reactivity with several aromatic heterocycles. Chapter 4 focuses on the electrochemical behavior of ferrocene-based uranium halide, alkyl, aryloxide, and amide ligands. Finally, Chapter 5 explains electrochemical, spectroscopic, and magnetic properties of uranium bis(1,1'-diamidoferrocene) complexes in an attempt to establish how well uranium mediates electronic communication between two iron centers.

Book Description
These studies describe the use of the redox-active 1,1'-diamidoferrocene ligand on uranium and group 5 metals. A novel terminal uranium-imide complex was synthesized using the bulky 2,6-dimesitylphenyl imide substituent as support. Although the uranium-imide was shown to be sterically accessible through the accommodation of another 2,6-dimesitylphenyl amide group, further reactivity was not seen, with the exception of sulfur. Electron transfer between the iron contained in the 1,1'-diamidoferrocene ligand and group 5 metals was more apparent than with uranium. A control reaction between ferrocene and niobium pentachloride suggested the formation of ferrocenium via electron transfer from iron to niobium. The use of a reduced tantalum and niobium precursors is required for coordination by 1,1'-diamidoferrocene ligands to prevent side reactions.

Book Description
Nuclear Magnetic Resonance is a powerful tool, especially for the identification of 1 13 hitherto unknown organic compounds. H- and C-NMR spectroscopy is known and applied by virtually every synthetically working Organic Chemist. Con- quently, the factors governing the differences in chemical shift values, based on chemical environment, bonding, temperature, solvent, pH, etc. , are well understood, and specialty methods developed for almost every conceivable structural challenge. Proton and carbon NMR spectroscopy is part of most bachelors degree courses, with advanced methods integrated into masters degree and other graduate courses. In view of this universal knowledge about proton and carbon NMR spectr- copy within the chemical community, it is remarkable that heteronuclear NMR is still looked upon as something of a curiosity. Admittedly, most organic compounds contain only nitrogen, oxygen, and sulfur atoms, as well as the obligatory hydrogen and carbon atoms, elements that have an unfavourable isotope distribution when it comes to NMR spectroscopy. Each of these three elements has a dominant isotope: 14 16 32 16 32 N (99. 63% natural abundance), O (99. 76%), and S (95. 02%), with O, S, and 34 14 S (4. 21%) NMR silent. N has a nuclear moment I = 1 and a sizeable quadrupolar moment that makes the NMR signals usually very broad and dif cult to analyse.

Book Description
This Special Issue is one of the first for the new MDPI flagship journal Chemistry (ISSN 2624-8549) which has a broad remit for publishing original research in all areas of chemistry. The theme of this issue is Supramolecular Chemistry in the 3rd Millennium and I am sure that this topic will attract many exciting contributions. We chose this topic because it encompasses the unity of contemporary pluridisciplinary science, in which organic, inorganic, physical and theoretical chemists work together with molecular biologists and physicists to develop a systems-level understanding of molecular interactions. The description of supramolecular chemistry as 'chemistry beyond the molecule' (Jean-Marie Lehn, Nobel Lecture and Gautam R. Desiraju, Nature, 2001, 412, 397) addresses the wide variety of weak, non-covalent interactions that are the basis for the assembly of supramolecular architectures, molecular receptors and molecular recognition, programed molecular systems, dynamic combinatorial libraries, coordination networks and functional supramolecular materials. We welcome submissions from all disciplines involved in this exciting and evolving area of science.

Book Description
Anion recognition plays a critical role in a range of biological processes, and a variety of receptors and carriers can be found throughout the natural world. Chemists working in the area of supramolecular chemistry have created a range of anion receptors, drawing inspiration from nature as well as their own inventive processes. This book traces the origins of anion recognition chemistry as a unique sub-field in supramolecular chemistry while illustrating the basic approaches currently being used to effect receptor design. The combination of biological overview and summary of current synthetic approaches provides a coverage that is both comprehensive and comprehensible. First, the authors detail the key design motifs that have been used to generate synthetic receptors and which are likely to provide the basis for further developments. They also highlight briefly some of the features that are present in naturally occurring anion recognition and transport systems and summarise the applications of anion recognition chemistry. Providing as it does a detailed review for practitioners in the field and a concise introduction to the topic for newcomers, Anion Receptor Chemistry reflects the current state of the art. Fully referenced and illustrated in colour, it is a welcome addition to the literature.

Book Description
The lanthanides and actinides (the f elements) are rarely studied in detail by chemistry undergraduates. More often they appear as an afterthought in bonding, spectroscopy, magnetism, coordination chemistry, and organometallics courses. This is largely because of a lack of an accessible text treating the chemistry of these elements in one cover. Moreover, the placement of lanthanides and actinides in the closing pages of standard inorganic chemistry text books serves to marginalise these elements further. The f elements has therefore been written to fill a gap in the undergraduate chemistry textbook market. It covers much of the fundamental chemistry of the lanthanide and actinide elements, including coordination chemistry, solid state compounds, organometallic chemistry, electronic spectroscopy, and magnetism. Many comparisons are made between the chemistry of the lanthanides and actinides and that of the transition elements, which is generally much more familiar to undergraduate chemistry students. The book uses the chemistry of the f elements as a vehicle for the communication of several important chemical concepts that are not usually discussed in detail in undergraduate courses, for example the chemical consequences of relativity and the lanthanide and actinide contractions. Many important modern applications of f element chemistry, e.g. the use of actinides in nuclear power generation and of the lanthanides in magnetic resonance imaging and catalytic converters in motor vehicle exhausts, are also discussed in depth.

Book Description
The design of ancillary ligands used to modify the structural and reactivity properties of metal complexes has evolved into a rapidly expanding sub-discipline in inorganic and organometallic chemistry. Ancillary ligand design has figured directly in the discovery of new bonding motifs and stoichiometric reactivity, as well as in the development of new catalytic protocols that have had widespread positive impact on chemical synthesis on benchtop and industrial scales. Ligand Design in Metal Chemistry presents a collection of cutting-edge contributions from leaders in the field of ligand design, encompassing a broad spectrum of ancillary ligand classes and reactivity applications. Topics covered include: Key concepts in ligand design Redox non-innocent ligands Ligands for selective alkene metathesis Ligands in cross-coupling Ligand design in polymerization Ligand design in modern lanthanide chemistry Cooperative metal-ligand reactivity P,N Ligands for enantioselective hydrogenation Spiro-cyclic ligands in asymmetric catalysis This book will be a valuable reference for academic researchers and industry practitioners working in the field of ligand design, as well as those who work in the many areas in which the impact of ancillary ligand design has proven significant, for example synthetic organic chemistry, catalysis, medicinal chemistry, polymer science and materials chemistry.
