Lum and published by . This book was released on 2013 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Abstract: Copper(I) complexes with fluorinated alkoxide ligands with the form K[Cu(OCRMe F2 )2 ], in which R = MeF ( 4 ), Ph (5 ), or Me (6 ), were synthesized and characterized. The dioxygen (O2 ) reactivity of the series of complexes was investigated at -78°C and two stoichiometries of {Cun O 2 }species were observed. Manometric O2 uptake studies showed dinuclear {Cu2 O2 } and triuclear {Cu3 O 2 } species and their chromophores were measured with UV-vis spectroscopy. Warming these species to room temperature resulted in irreversible spectroscopic changes, and ligand hydroxylation was observed for complexes 5 and 6. ESI-MS study of reactions with 18 O 2 confirmed O2 as the source of the ligand hydroxyl O atom. A tetrameric Cu(II) carbonate complex, {{K2 (DME)1.5 }[Cu(OCMeMe F2 )2 CO3 ]}4 (14 ), was obtained from CO2 addition to the {Cu2 O3 } moiety derived from 6. Irreversible reduction of O2 required secondary potassium-ligand (K···F and K-O) interactions which bridge multiple [Cu(OCRMe F2 )2 ]- anions in solid-state structures of 4, 5, and 6, and were quantified by K+ cation bond valence analysis. Solution conductivity studies confirmed that neutral aggregates of K[Cu(OCRMeF2 ) 2 ] complexes are retained in solution. Ionic copper(I) complexes of the form {K(18C6)}[Cu(OCRMeF2 )2 ] in which R = MeF (7 ), Ph (8 ), or Me ( 9 ) and (Ph4 P)[Cu(OCRMeF2 ) 2 ], with R = MeF (10 ) were prepared, none of which react with O2 at -78°C. The Cu(II) alkoxide compounds {K(18C6)}[Cu(OCRMeF 2 )3 ], in which R= MeF (15 ) and Me (16 ) were prepared and spectroscopically and magnetically characterized. Compound 16 was demonstrated to be trigonal-planar by X-ray crystallography and all other data for 15 are consistent with trigonal-planar coordination. Two four-coordinate Cu(II) compounds with dodecafluoropinacolate (ddfp) ligands were also synthesized and characterized spectroscopically. The structurally characterized square-planar ddfp compounds have the form {K(solvent) 2 }2 [Cu(ddfp)2 ], in which solvent = H2 O (17 ) or DME (18 ). Diamagnetic Zn(II) derivatives with aryloxide ligands of the form {K(18C6)} 2 [Zn(OAr)4 ], in which Ar = ArF (19 ) or Ar' (20 ) and {K(18C6)}[Zn(OCRMeF2 ) 3 ], with R = Ph (21 ) were also prepared and characterized by X-ray crystallography and multinuclear NMR.
Download or read book Surface Organometallic Chemistry Molecular Approaches to Surface Catalysis written by Jean-Marie Basset and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface organometallic chemistry is a new field bringing together researchers from organometallic, inorganic, and surface chemistry and catalysis. Topics ranging from reaction mechanisms to catalyst preparation are considered from a molecular basis, according to which the "active site" on a catalyst surface has a supra-molecular character. This. the first book on the subject, is the outcome of a NATO Workshop held in Le Rouret. France, in May. 1986. It is our hope that the following chapters and the concluding summary of recommendations for research may help to provide a definition of surface organometallic chemistry. Besides catalysis. the central theme of the Workshop, four main topics are considered: 1) Reactions of organometallics with surfaces of metal oxides, metals. and zeolites; 2) Molecular models of surfaces, metal oxides, and metals; 3) Molecular approaches to the mechanisms of surface reactions; 4) Synthesis and modification of zeolites and related microporous solids. Most surface organometallic chemistry has been carried out on amorphous high-surf ace-area metal oxides such as silica. alumina. magnesia, and titania. The first chapter. contributed by KNOZINGER. gives a short summary of the structure and reactivity of metal oxide surfaces. Most of our understanding of these surfaces is based on acid base and redox chemistry; this chemistry has developed from X-ray and spectroscopic data, and much has been inferred from the structures and reactivities of adsorbed organic probe molecules. There are major opportunities for extending this understanding by use of well-defined (single crystal) oxide surfaces and organometallic probe molecules.

Download or read book Hydrosilylation written by Bogdan Marciniec and published by Springer Science & Business Media. This book was released on 2008-11-09 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: For fifty years, Hydrosilylation has been one of the most fundamental and elegant methods for the laboratory and industrial synthesis of organosilicon and silicon related compounds. Despite the intensive research and continued interest generated by organosilicon compounds, no comprehensive book incorporating its various aspects has been published this century. The aim of this book is to comprehensively review the advances of hydrosilylation processes since 1990. The survey of the literature published over the last two decades enables the authors to discuss the most recent aspects of hydrosilylation advances (catalytic and synthetic) and to elucidate the reaction mechanism for the given catalyst used and the reaction utilization. New catalytic pathways under optimum conditions necessary for efficient synthesis of organosilicon compounds are presented. This monograph shows the extensive development in the application of hydrosilylation in organic and asymmetric syntheses and in polymer and material science.
Download or read book Nanostructured Catalysts written by Susannah L. Scott and published by Springer Science & Business Media. This book was released on 2008-04-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the recent advent of nanotechnology, research and development in the area of nanostructured materials has gained unprecedented prominence. Novel materials with potentially exciting new applications are being discovered at a much higher rate than ever before. Innovative tools to fabricate, manipulate, characterize and evaluate such materials are being developed and expanded. To keep pace with this extremely rapid growth, it is necessary to take a breath from time to time, to critically assess the current knowledge and provide thoughts for future developments. This book represents one of these moments, as a number of prominent scientists in nanostructured materials join forces to provide insightful reviews of their areas of expertise, thus offering an overall picture of the state-- the art of the field. Nanostructured materials designate an increasing number of materials with designed shapes, surfaces, structures, pore systems, etc. Nanostructured materials with modified surfaces include those whose surfaces have been altered via such techniques as grafting and tethering of organic or organometallic species, or through various deposition procedures including electro, electroless and vapor deposition, or simple adsorption. These materials find important applications in catalysis, separation and environmental remediation. Materials with patterned surfaces, which are essential for the optoelectronics industry, constitute another important class of surface-modified nanostructured materials. Other materials are considered nanostructured because of their composition and internal organization.

Download or read book Structural Chemistry of Silicates written by F. Liebau and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: As natural minerals, silica and silicates constitute by far the largest part of the earth's crust and mantle. They are equally important as raw materials and as mass produced items. For this reason they have been the subject of scientific research by geoscientists as well as by applied scientists in cement, ceramic, glass, and other industries. Moreover, intensive fun damental research on silicates has been carried out for many years because silicates are, due to their enormous variability, ideally suited for the study of general chemical and crystallographic principles. Several excellent books on mineralogy and cement, ceramics, glass, etc. give brief, usually descriptive synopses of the structure of silicates, but do not contain detailed discussions of their structural chemistry. A number of monographs on special groups of silicates, such as the micas and clay min erals, amphiboles, feldspars, and zeolites have been published which con tain more crystal chemical information. However, no modern text has been published which is devoted to the structural chemistry of silicates as a whole. Within the last 2 decades experimental and theoretical methods have been so much improved to the extent that not only have a large number of silicate structures been accurately determined, but also a better under standing has been obtained of the correlation between the chemical composition of a silicate and its structure. Therefore, the time has been reached when a modern review of the structural chemistry of silicates has become necessary.
