The selective catalytic oligomerization of ethylene to alpha-olefins constitutes a process of significant scientific as well as economic interest both in industry and academics. The present thesis gives both experimental and theoretical contributions to the catalyzed selective tri- and tetramerization with chromium coordination complexes. Important aspects of the mechanism of this reaction are adressed, including the oxidation state of the active species, the origin of cyclic secondary products, as well as the influence of the ligand steric bulk, are comprehensively adressed. A number of alternative bidentate ligands have been evaluated in the oligomerization reaction. Another part of this thesis concerns the selective ethylene dimerization with nickel(II) complexes bearing mixed heteroatomic iminophosphorane (N,O), (N,S), and (N,P) ligands. The synthesis of these new ligands, their coordination to Ni(II), as well as the catalytic evaluation of the obtained complexes are reported. The last part of this work concerns the preparation of two new phosphatitanocenes and catalytic evaluation in the ethylene oligomerization/polymerization reaction.

Comprehensive Coordination Chemistry II (CCC II) is the sequel to what has become a classic in the field, Comprehensive Coordination Chemistry, published in 1987. CCC II builds on the first and surveys new developments authoritatively in over 200 newly comissioned chapters, with an emphasis on current trends in biology, materials science and other areas of contemporary scientific interest.

Most syntheses in the chemical research laboratory fail and usually require several attempts before proceeding satisfactorily. Failed syntheses are not only discouraging and frustrating, but also cost a lot of time and money. Many failures may, however, be avoided by understanding the structure-reactivity relationship of organic compounds. This textbook highlights the competing processes and limitations of the most important reactions used in organic synthesis. By allowing chemists to quickly recognize potential problems this book will help to improve their efficiency and success-rate. A must for every graduate student but also for every chemist in industry and academia.
