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 Organometallic Catalysis for Controlled Olefin Polymerization and Oligomerization written by Kyung-Sun Son and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: My Ph. D. work primarily involves the synthesis of ethylene-based oligomers and ethylene-styrene copolymers using organometallic catalysis. Chapter 1 reviews selective ethylene oligomerization that produces 1-hexene and 1-octene, with particular emphasis on the chromium-based catalytic systems and the mechanism by which they operate. Its application to the preparation of value-added chemicals is also covered. Chapter 2 and Chapter 3 present investigations on selective ethylene oligomerization with a Cr(PNP)Cl3/MAO catalyst system (PNP = Ph2PN(iPr)PPh2) in the presence of dialkyl zinc as an effective strategy for the co-generation of 1-octene and functionalized ethylene oligomers. Transmetallation with ZnMe2 during Cr-catalyzed ethylene tetramerization generated end-labeled 1-alkenes in Cn> 10 along with 1-octene, while that with ZnEt2 or ZnBu2 produced a mixture of end-labeled linear alkanes and 1-alkenes in Cn> 10 as well as 1-octene. Labeling studies with D2O provided a mechanistic test for metallacycle intermediates. Mechanistic proposals are presented to explain the formation of end-labeled products in the presence of various types of zinc alkyls. Chapter 4 and Chapter 5 examine a series of titanocenes [CpTiCl3, CpTiCl2TEMPO, CpNTiCl3, CpNTiCl2TEMPO, where Cp = C5H5, CpN = C5H4CH2CH2N(CH3)2, and TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl] for styrene homopolymerization and ethylene-styrene (ES) copolymerization at 70 °C and 120 °C to determine the influence of the pendant amine group and the hydroxylaminato ligand on comonomer incorporation and distribution. Titanocenes bearing the pendant amine ligand were active for ES copolymerization, whereas complexes lacking the pendant group afforded only mixtures of homopolymers, revealing the critical role of the pendant amine donor on the copolymerization behavior. At 120 °C, the titanocene complexes with the amine group generated high molecular weight ES copolymers along with an atactic polystyrene (aPS) byproduct. The molecular weight of the ES copolymers produced by a coordination mechanism was found to coincide with that of the aPS produced by a radical polymerization mechanism. A method to separate these two components was developed by the addition of a catalytic chain-transfer agent, cobalt tetraphenylporphyrin, successfully decreasing the molecular weight of the radically-produced aPS and offering expedient separation of the ES copolymer from the aPS. Chapter 6 describes a series of new mono-, bi-, and trimetallic complexes based on the dinucleating ligand, N, N'-bis[2-(diphenylphosphino)phenyl] formamidine (PNNP), which provides two binding sites suitable for accommodating Pd, Ni, Co, Fe, and Cu. Definitive evidence for the structures of all complexes were given by X-ray crystal structures. The synthesis, characterization and crystal structure of each complex are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Heterocycles are ubiquitously present in nature and occupy a unique place in organic chemistry as they are part of the DNA and haemoglobin that make life possible. The Chemistry of Heterocycles covers an introduction to the topic, followed by a chapter on the nomenclature of all classes of isolated, fused and polycyclic heterocycles. The third chapter delineates the highly strained three membered N,O and S containing aromatic and non-aromatic heterocycles with one and more than one similar and dissimilar heteroatom. The four-membered heterocycles are abundantly present in various natural and synthetic products of pharmacological importance. This chapter describes the natural abundance, synthesis, chemical reactivity, structural features and their medicinal importance. This class of compounds are present as sub-structures in penicillin and cytotoxic Taxol. Lastly, a chapter on the natural abundance, synthesis, chemical reactivity and pharmacological importance of 5-membered heterocycles with N,O,S heteroatom is covered. The chemistry of heterocycles with mixed heteroatom such as, N-S, N-O, N-S etc. is also described. Gives in-depth, clear information about various systems of nomenclature along with widely acceptable IUPAC system for naming various classes of heterocycles Provides complete information about natural occurrences, synthesis, chemical reactivity, pharmacological importance of heterocycles and their application in material science Highly relevant for graduate students and researchers, providing updated information about various isolated and fused N,O and,S containing heterocycles
