New Aspects of Zirconium Containing Organic Compounds by Ilan Marek Pdf

Metal carbene complexes have made their way from organometallic curiosities to valuable reagents and catalysts. They offer novel synthetic opportunities in carbon-carbon bond formation based on either carbene-centered reactions or on metal-templated processes which makes them indispensable in modern synthetic methodology. The most prominent metal carbenes are now either commercially available or easy to synthesize and handle with modern laboratory techniques. This volume organized in eight chapters written by the leading scientists in the field illustrates the theoretical background, non-classical nucleophilic and cycloaddition patterns, chromium-templated benzannulation and photo-induced reactions, rhodium-catalyzed carbene transfer as well as the principles and applications of olefin metathesis which has coined the progress in synthetic methodology over the past decade. Designed for researchers in academia and industry as well as graduate students it presents the state-of-the-art potential of carbene complexes in modern organic synthesis.

The Chemistry of Zirconacycles and 2,6-Diazasemibullvalenes by Shaoguang Zhang Pdf

In this thesis, the author introduces two strategies used to construct various types of N-heterocycles, based on the chemistry of zirconacycles and 2,6-diazasemibullvalenes. In the first part, the author presents the development of multi-component cyclization of a zirconacyclobutene-silacyclobutene fused compound, nitriles and unsaturated compounds. These reactions provide synthetically useful methodology for various N-heterocycles such as 3-acyl pyrrole, pyrrolo[3,2-d]pyridazine and dihydropyrroloazepine, which are all difficult to synthesize by other means. The isolation and characterization of the key three-fused-ring Zr/Si-containing intermediates are also described in detail. These results show that the zirconacyclobutene-silacyclobutene fused compound behaves as a “chemical transformer” upon treatment with various substrates via the “coordination-induced skeleton rearrangement” mechanism. In the second part, the author demonstrates the synthesis and isolation of a series of 2,6-diazasemibullvalenes (NSBVs) from the reaction of 1,4-dilithio-1,3-dienes and nitriles, highlighting the significant progress made for the first time in this work: (1) determination of X-ray crystal structure of a substituted 2,6-diazasemibullvalene; (2) measurement of the activation barrier of its rapid intramolecular aza-Cope rearrangement in solution; (3) exploration of several reaction types of NSBV with diverse ring-expansion products and “bowl-shape” or “cage-shape” N-containing polycyclic skeletons; (4) demonstration of the localized structure as the predominant form and the homoaromatic delocalized structure as a minor component in the equilibrium using theoretical analysis. Based on well-founded results, this work sheds new light on this controversial topic.

Organometallic Chemistry of Titanium, Zirconium, and Hafnium by P.C. Wailes Pdf

Organometallic Chemistry of Titanium, Zirconium, and Hafnium covers the chemistry of organic complexes of titanium, zirconium, and hafnium having metal-to-carbon linkage. This book is organized into eight chapters that consider the significant developments in delineating the chemistry of these metal derivatives. This book starts with a description of the stability and bonding in cyclopentadienyl derivatives of the metals, based on the thermodynamic and spectroscopic evidence. The remaining chapters discuss the preparation and reactions of titanium-, zirconium-, and hafnium-bonded organic compounds. These chapters also look into the synthetic difficulties encountered from the reactions and preparation of these compounds. The stabilization and adduct formation of these metal complexes are also explored. Organic chemists and organic chemistry researchers and students will find this book invaluable.
