Download or read book Mechanistic Investigations Into the Thermal C C Bond Forming Cyclization of Metal Pyridine Enamide Complexes and the Synthesis and Reactivity of Cationic and Neutral Iron IV Alkylidene Complexes written by Brian Lindley and published by . This book was released on 2016 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of first row transition metal pyridine-enamide complexes has been synthesized. In the course of reactivity studies, it was discovered that heating a solution of the cobalt bis(pyridine-enamide) pyridine adduct resulted in intraligand CC coupling to form an indolamide ligand. Control experiments with the corresponding lithium pyridine-enamide afforded the same indolamide. In order to probe the mechanism of cyclization, deuterium labeling experiments for the lithium pyridineenamide compound were conducted. Careful kinetics measurements supported a mechanism consisting of reversible hydrogen transfer followed by rate-determining CC bond formation, in accord with computational results. Iron(II) complexes bearing cyclometalated benzyldialkylphosphine ligands were synthesized via a salt metathesis approach by treating FeCl2(PMe3)2 with two equivalents of (2-lithiobenzyl)diphenyl- and (2-lithiobenzyl)dicyclohexylphosphine reagents. For the phenyl derivative, a 6-coordinate diamagnetic complex containing two chelating phosphine ligands and two trimethylphosphine ligands was obtained. Contrarily, for the cyclohexyl derivative, a 5-coordinate complex containing two chelating phosphines and one molecule of trimethylphosphine was obtained. This compound is paramagnetic with an S = 1 ground state. Efforts to synthesize Fe(IV) alkylidenes by treating these Fe(II) complexes with diphenyldiazomethane were ultimately unsuccessful. An iron(II) vinyl complex was synthesized by reaction of cis-Me2Fe(PMe3)4 with a 2-propynylaniline benzylidene ligand. Protonation of this complex with [H(OEt2)2]BArF4 (BArF4 = B(3,5-(CF3)2C6H3)4) gave access to a cationic Fe(IV) alkylidene complex. By treating this complex with different anionic nucleophiles, a rare series of neutral Fe(IV) alkylidene complexes was obtained. In addition, treatment of the cationic alkylidene complex with MeMgCl afforded a novel Fe(IV) methyl complex. Attempts at catalyzing olefin metathesis with both the cationic and neutral alkylidene complexes proved unsuccessful, likely due to recalcitrant phosphine dissociation and the sterics at the alkylidene carbon.

This book was released on 2011-05-19 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Olefin Upgrading Catalysis by Nitrogen-based Metal Complexes II: State-of-the-art and Perspectives provides a critical review of the state-of-the-art developments in industrially relevant processes connected to efficient and selective olefin upgrading. Specific attention is devoted to catalysts containing imine- and amine-based ligands. All the chapters in this book have been designed to provide a systematic account of the vast amount of information available for this type of catalyst as well as to highlight the factors that ultimately control the catalyst’s performance and productivity. A comprehensive panorama of catalyst precursors is presented, spanning from group 10 α-diimine complexes and iron and cobalt 2,6-bis(imino)pyridine derivatives, to vanadium, chromium, titanium, zirconium and lanthanide complexes supported by nitrogen-containing ligands. The authors of this collective work are currently involved in the development of imine-based catalysts for efficient and selective olefin upgrading and the majority of them have dedicated most of their scientific career to this important field. In writing this book, their major goal is to transfer as many ideas and experiences as possible to the global audience of scientists engaged in this area of research.
Download or read book Olefin Polymerization written by Walter Kaminsky and published by Wiley-VCH. This book was released on 2006-08-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Synthesis And Applications In Chemistry And Materials In 4 Volumes written by Armando J L Pombeiro and published by World Scientific. This book was released on 2024-01-16 with total page 2103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemistry and Material Sciences naturally depend greatly on Synthesis as the initial stage for the existence of compounds and materials with desired behaviors, within the overall streamline of Design/Synthesis — Properties — Application/Function, and their relations. Such a general approach is of a too wide scope to be properly treated in a single set of publications, but this one on 'Synthesis and Applications in Chemistry and Materials' restricts itself by aiming to show the strength and international character of the current research in synthetic chemistry that is being developed in Portugal or abroad by teams that cooperate with this country. Hence, it gathers representative contributions of main Portuguese research groups and foreign collaborating ones. Nevertheless, the topic should be understood in a wide sense, being open to types of studies with significance on sustainable synthesis and applications in chemistry, materials and/or related sciences.
