The synthesis of transition metal complexes containing redox-active ligands or ligands with redox-active substituents have been areas of ongoing interest in chemical research. To date, only a handful of examples involving redox-active ligands containing main group centres have been reported. This thesis presents work on the development of novel redox-active ligands utilizing an assortment of nitrogen-based frameworks (diiminopyridine (DIMPY), 1,4-diaza-1,3-butadiene (DAB), N-heterocyclic carbene (NHC)) that contain metallocene substituents (ferrocene and an understudied redox-active Co(III) moiety). Initially the syntheses of an N, N'-differocenyl diiminopyridine and its low-valent chalcogen (S2+, Se2+, Te2+) and pnictogen (P+) complexes are discussed. These complexes represent the first such examples of utilizing low-valent main group systems containing redox-active ligands with pendant ferrocenyl substituents. Other work focuses on the synthesis of the above listed nitrogen-based ligands containing novel mixed sandwich Co(III) substituents, and include comparative reactivity studies (SnCl2 and GeCl2.dioxane for DIMPY and SnCl4 and Pt2Me4(SMe2)2 for DAB) of those ligands to their ferrocene derivatives. Electrochemical studies reveals an instability of the Co(III) containing complexes, leading to the continuous variation in the ligand framework towards a more stable compound.

That terms like sandwich complexes or the concept of compounds without direct chemical bonds between the central metal atom and the ligating atoms are nowadays common knowledge can be attributed to the sensational discovery of ferrocene in the early 1950s. Although ferrocene is still at the forefront of research, this two-volume book highlights the development of metallocene chemistry, and emphasizes the similarities and differences between ferrocene and other metallocenes. Do you require a transition metal to build metallocenes? Must the planes of the cyclopentadienyl ligands be parallel to allow the compound to behave like a typical metallocene? Do zirconocenes react by the same mechanism as molybdenocenes? What are the (potential) applications of these substances? Let yourself be guided by the leading experts in this field, and learn all about the synthesis, reactivity, and unique properties of these sandwich complexes. If you are more interested in applications, there is a wealth of polymeric and dendritic materials with metallocene building blocks described herein. This book also focusses on metallocenes as catalysts in polymerization or asymmetric reactions. If you are graduate student or researcher in organic, inorganic, organometallic, polymer chemistry, and materials science you will find this book an inspiring source of ideas for your own research.

With an enormous velocity, olefin polymerization has expanded to one of the most significant fields in polymers since the first industrial use about 50 years ago. In 2005, 100 million tons of polyolefins were produced - the biggest part was catalyzed by metallorganic compounds. The Hamburg Macromolecular Symposium 2005 with the title "Olefin Polymerization" involved topics such as new catalysts and cocatalysts, kinetics, mechanism and polymer reaction engineering, synthesis of special polymers, and characterization of polyolefins. The conference combined scientists from different disciplines to discuss latest research results of polymers and to offer each other the possibility of cooperation. This is reflected in this volume, which contains invited lectures and selected posters presented at the symposium.
