Book Description
This thesis deals with the Ti(III) catalyzed synthesis of exocyclic allenes and the development of new titanocene complexes. It is structured in six chapters: Chapter 1 is a general introduction about the generation and reactivity of [TiCp2Cl]. A review about the different [TiCp2Cl] catalyzed or promoted reactions reported to date, is included. Chapter 2 is divided in introduction and results and discussion. In the introduction, an overview about the promoted or catalyzed methodologies, already available for the synthesis of α-allenols, is included. Results and discussion section is sub-divided in other two parts. The first one describes the synthesis of carbocyclic or nitrogen heterocyclic precursors bearing a propargyl halide and a carbonyl group. Next, the [TiCp2Cl] catalyzed synthesis of exocyclic allenols is studied. Additionally, a mechanistic study through deuterium incorporation and reaction of secondary propargyl halide precursors is performed. In the second part, the preparation of oxygen precursors and its cyclization are studied. In chapter 3, there is an introduction about enantioselective syntheses using chiral titanocene catalysts. The results and discussion section deals with the enantioselective cyclization of some of the precursors previously prepared using precatalyst (R,R)-ethylenebis(4,5,6,7-tetrahydro-1-indenyl) titanium(IV), also known as Brintzinger complex. A formal synthesis of the alkaloid (})-stemoamide is carried out in chapter 4, being the key step for this synthesis the generation of an α-allenol derivative through a [TiCp2Cl] catalyzedcyclization. This chapter is also divided in an introduction, in which a review about the different methods of synthesis of stemoamide are included, and results and discussion. Chapter 5 compiles the project that I have developed during my research stay at University of Bonn, under the supervision of Prof. Gansauer. The target of this project was to develop an azide functionalized short linker titanocene derivative with the aim of linking it to a surface by click chemistry. The chapter is divided in introduction and results and discussion. In the introduction the different methodologies for the synthesis of titanocene derivatives are reviewed. This section also includes the background in which this project is based. Chapter 6 includes the experimental part. In this chapter all reactions performed during the development of this thesis, as well as the spectroscopic characterization of compounds, are compiled.

Book Description
This book deals with adsorption and catalysis on the surface of transition elements and their compounds, many of which are in teresting because of their particular electronic structure. The authors have worked through a vast body of experimental evi dence on the structure and properties of surfaces of transition metals and relevant oxides. Consideration is given mostly to simple (as opposed to mixed) oxides of transition elements, to common metals and to the adsorption of simple gases. A great deal of attention is paid to the nature of active surface sites responsible for chemisorption and catalytic transformations. The description relies mainly on the simplified ligand-field theory, which, however, proves quite satisfactory for predicting the adsorptive and catalytic activity of species. In many cases simple systems were explored with the aid of novel techniques, and it is only for such systems that the mechanism of the ele mentary act of adsorption and catalysis can be given adequate treatment. The present monograph has emerged from our earlier work in Russian, which appeared in the Khimiya Publishing House (Mos cow) in 1981. This English edition has, however, been revised completely to broaden its scope and to include more recent a chievements. For fruitful discussions the authors are grateful to A.A.

Book Description
This volume builds on the previous two editions, Environmental Photochemistry Part I and Part II, which reflect the diverse range of activities in this highly dynamic research field. The chapters cover fundamental topics, from photocatalyst materials, surface-modified materials, reaction kinetics and reactor modelling, to translational research activities on chemical synthesis, energy conversion and water treatment. The applications of the new generation of LED irradiation sources and spectroscopic methods for elucidating reaction pathways are also covered in detail. This new volume maintains the ethos of the previous editions by further contributing to readers’ understanding of photochemical and photocatalytic processes for environmental applications.

Book Description
At long last: The second, completely revised edition of this comprehensive standard reference. Alwyn G. Davies has updated the contents of his book to reflect the current state of research into organotin chemistry. He covers all aspects in detail, such as its synthesis, characterization, structures and applications, while also devoting space to such hot topics as environmental issues. This new edition also includes a CD-ROM with more than 5,000 references, making this database an invaluable tool for everyone working in the field. "The text is well written, extremely accessible and very comprehensive: particularly impressive is the inclusion of up-to-the-minute references in these areas...." - Advanced Materials, 13 (1998) "The standard of production is very good, with well-structured tables and an abundance of clear formula schemas, which enable the reader to quickly grasp the essence of the text." - Angewandte Chemie 16, 1997

Book Description
Transition metal ions in biological systems are of interest in biology, biochemistry, chemistry, medicine, and physics. Scien tists with rather different viewpoints, employing many methods, have contributed to this area. A concise review of the current state of the field will, to some extent, reflect the special knowledge of the person writing it - in this case application of physical methods to the investigation of metal coordination. x ray diffraction is one of the most important of these methods, but a useful treatment of X-ray structure analysis would be com parable in size with and beyond the scope of the monograph. Many results of X-ray diffraction studies are, of course, presented. Electron paramagnetic resonance spectroscopy has played a major part in the rapid advance in knowledge of the electronic struc tures of transition metal ions in biological systems. More gener ally, measurements involving light, microwaves, and magnetic fields are capable of producing much new information, and the required instrumentation is available at most research institu tions. Therefore light absorption and paramagnetic resonance are treated in depth. The principles described in the latter discus sions are broadly applicable, for example to the promising tech niques of X-ray spectroscopy (utilizing synchrotron radiation) and lanthanide-perturbed, very high-resolution nuclear magnetic resonance spectroscopy.
