Download Organochromium Chemistry with Formally Neutral, Chelating Ancillary Ligands Book in PDF, Epub and Kindle
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.

Download Organochromium compounds Book in PDF, Epub and Kindle
Organochromium Compounds is a three-chapter text that covers the major developments in the preparation, characterization, and reaction of the five main classes of organochromium compounds. These classes include the chromium p and solvated sodium and lithium poly(organo)chromate(III) and (II) complexes, carbenoid-chromium, solvated s-bonded organochromium(III) and (II), solvated sodium and lithium poly(organo)chromate(III) and (II) complexes, and unsolvated s-bonded tetra(organo)chromium(IV) compounds. This book will be of value to organic chemists and researchers who are interested in organotransition metal chemistry.

Download Molecular Catalysts Book in PDF, Epub and Kindle
Highlighting the key aspects and latest advances in the rapidly developing field of molecular catalysis, this book covers new strategies to investigate reaction mechanisms, the enhancement of the catalysts' selectivity and efficiency, as well as the rational design of well-defined molecular catalysts. The interdisciplinary author team with an excellent reputation within the community discusses experimental and theoretical studies, along with examples of improved catalysts, and their application in organic synthesis, biocatalysis, and supported organometallic catalysis. As a result, readers will gain a deeper understanding of the catalytic transformations, allowing them to adapt the knowledge to their own investigations. With its ideal combination of fundamental and applied research, this is an essential reference for researchers and graduate students both in academic institutions and in the chemical industry. With a foreword by Nobel laureate Roald Hoffmann.

Download Machine Learning in Chemistry Book in PDF, Epub and Kindle
Recent advances in machine learning or artificial intelligence for vision and natural language processing that have enabled the development of new technologies such as personal assistants or self-driving cars have brought machine learning and artificial intelligence to the forefront of popular culture. The accumulation of these algorithmic advances along with the increasing availability of large data sets and readily available high performance computing has played an important role in bringing machine learning applications to such a wide range of disciplines. Given the emphasis in the chemical sciences on the relationship between structure and function, whether in biochemistry or in materials chemistry, adoption of machine learning by chemistsderivations where they are important

Download The Chemistry of Mycotoxins Book in PDF, Epub and Kindle
The biological activity of mycotoxins ranges from weak and/or sometimes positive effects, such as antibacterial activity (see penicillin derivatives derived from Penicillium strains) to strong mutagenic (e. g. aflatoxins, patulin), carcinogenic (e. g. aflatoxins), teratogenic, neurotoxic (e. g. ochratoxins), nephrotoxic (e. g. fumonisins, citrinin), hepatotoxic, and immunotoxic (e. g. ochratoxins, diketopiperazines) activity. Nowadays, many laboratories around the world are specialized in the detection of mycotoxins in food products and contaminated material found in housing. In this volume, a focus on the most important classes of mycotoxins is provided and their chemistry of the last ten years is discussed. In each Section, the individual biological impact is outlined. Sections are arranged according to mycotoxin classes (e. g. aflatoxins) and/or structural classes (e. g. resorcinyl lactones, diketopiperazines). The biology of mycotoxins is also described.

Download Olefin Upgrading Catalysis by Nitrogen-based Metal Complexes I Book in PDF, Epub and Kindle
This book highlights key advances that have occurred in the field of olefin conversion in recent years. The role of homogenous transition metal catalysts which contain an imine functionality is emphasized; their potential applications in the processing and upgrade of olefins to a wide variety of commodity products of very high industrial value is also explored. On the threshold of the fiftieth anniversary of the Noble Prize to Ziegler and Natta, this book gives a critical summary of the state of the art developments in the fascinating and rapidly developing field of the olefin polymerization, oligomerization, and co-polymerization catalysis.

Download Topics in Inorganic and Organometallic Stereochemistry Book in PDF, Epub and Kindle
This volume is devoted entirely to inorganic and organometallic stereochemical subjects. Discusses the systematic notations that have been developed to satisfy the needs for a rational and systematic stereochemical nomenclature. Reviews the stereochemical aspects of the changes of bonding at carbon centers induced by metals, either catalytically or stoiciometrically. Also reviews the major achievements in current stereochemical research—the synthesis of asymmetric compounds mediated by transition metals. Discusses the structures of transition metal carbonyl clusters, summarizing recent progress in this expanding area and providing a semiquantitative rationalization of the structures for these clusters.
