This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 3: Having synthesized LiPrCr(N)(R) in Chapter 2, we explored the oxidation, nucleophilic attack and reduction reactions to study nitride migratory insertion mechanism. Oxidation led to the loss of alkyl ligands, reduction ofLiPrCr(N)(CH2TMS) (3c) resulted in two 3c molecules bridged by two K atoms, and nucleophilic attack on the nitrido ligand did not happen.

Download or read book Photochemistry and Photophysics of Coordination Compounds written by Rakshit Ameta and published by Elsevier. This book was released on 2023-06-24 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photochemistry and Photophysics of Coordination Compounds: Fundamentals and Applications provides a systematic overview of the photochemical and photophysical properties of coordination compounds with different metal cores. Beginning with a clear introduction to the fundamentals of both photochemistry and coordination chemistry, the book goes on to outline the photochemical and photophysical properties of a large range of coordination compounds, clustering metal cores together in chapters according to their period table group, ranging across Transition metals, Lanthanides and Actinides. In addition to outlining their properties, each chapter discusses the synthesis, current applications and future potential of coordination compounds in each group. Drawing on the experience of a global team of experts, this book is an authoritative guide for all those interested in understanding and harnessing the photochemical properties and potential applications of coordination complexes for their own work. Introduces the fundamentals of both photochemistry and coordination compounds Supports learning through carefully structured content, with chapters uniquely arranged by period table group Bridges the knowledge gap between theory and practice by presenting application examples in each chapter
Download or read book Synthesis Characterization and Catalytic Activity of Chromium Complexes written by Joanna Gurnham and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a growing demand for specific linear alpha olefins in the polyethylene industry in order to control polymer rheology. This growing demand thereby increases the need for highly active and selective ethylene oligomerization catalysts. Chromium-based catalysts continue to be of high interest for this application due to this metal's versatility in both selective and non selective ethylene oligomerization. Ligand design is an important consideration in oligomerization chemistry: the ability of the ligand to stabilize low valent chromium and to support a two-electron redox process will allow the catalytic systems to follow the selective ring expansion mechanism for oligomerization. Chelating aminophosphane based ligands, previously studied by our group, have been shown to support both tri- and tetramerization of ethylene. We have explored modifications of one of the NP arms by replacing with a different coordinating group in an attempt to further stabilize the monovalent state of chromium and increase selectivity. Other ligands explored in this work are pyrrole based ligands, which have shown high activity and selectivity towards ethylene oligomerization. One example of this is the commercial Chevron-Phillips system. Recently, the co-polymerization of CO2 with epoxides has been studied as an environmentally friendly route to convert CO2 into biodegradable polymers. The first successful catalytic system to achieve these results consisted of a diethyl-zinc complex. More recently, aluminum, chromium, cadmium and cobalt have been studied as polycarbonate catalysts. To date, the only reported chromium catalysts for CO2-epoxide copolymerization are Cr-salen and Cr-porphyrin complexes, studied by Darrensbourg and Holmes, respectively. We were particularly interested in finding new chromium-based complexes able to catalyze epoxide/CO2 copolymerization by using molecules with the nitrogen donor motif embedded in different functions such as neutral pyridines with anionic pendants, pyrroles with either imine or amine pendants, or a combination of these.

Download or read book Organochromium Chemistry with Formally Neutral Chelating Ancillary Ligands written by Kevin Allen Kreisel and published by ProQuest. This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes research on chromium complexes with formally neutral, chelating ligands. The goal of this research is the fundamental study of organochromium chemistry with the hope of preparing Cr(II) complexes that are active for the polymerization or oligomerization of ethylene. This would provide evidence for Cr(II) to be active for these processes. Chapter 1 of this dissertation describes the synthesis and characterization of a series of chromium complexes supported by a chelating N-heterocyclic carbene ligand. The second chapter details the preparation and structural characterization of several complexes of chromium supported by several diimine ligands. The third chapter examines the organochromium chemistry derived from the complexes described in chapter 2. The final chapter entails the synthesis of the shortest metal-metal distance ever reported.
