Book excerpt: The investigation and development of heterobimetallic systems has seen a meteoric surge over the past decade. Generally, these heterobimetallic systems involve two transition metals with distinct properties used together to activate chemical bonds. Many heterobimetallics consist of a soft, low-valent metal and a harder, high-valent metal. The unique electronics afforded by heterobimetallics of this sort can be exploited, yielding access to novel reactivities that may be otherwise inaccessible to a single transition metal. Less studied are heterobimetallic complexes composed of one late transition metal (LTM) and one Lewis-acidic p-block (Group 13) metal. Due to its electropositivity being the highest among Group 13 metals as well as its high earth-abundance, aluminum holds particular interest to the Brewster laboratory. In contrast to their exhaustively investigated boron analogues, the field of aluminum-containing heterobimetallics is relatively uncultivated due to the high reactivity and synthetic difficulty of aluminum species, making isolation and characterization quite challenging. One of the aims of the Brewster lab is to develop heterobimetallic systems comprised of an electron-rich, low-valent transition metal and aluminum to investigate potential synergistic reactivity between both metal centers. In this dissertation, I report the successful synthesis and electronic characterization of myriad novel mono- and heterobimetallic complexes of either iridium or rhodium and aluminumover 35 new complexes in total. Moreover, I detail the ability of selected heterobimetallic complexes to facilitate activation of molecular hydrogen as well as hydrogenolysis, thereby generating alkane gas..

This book was released on 2017 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work described herein focuses on the synthesis and characterization of new heterobimetallic complexes containing the redox-active W[SNS] 2 metalloligand and investigation into their electronic properties and reactivity. Most recent studies have explored the redox nature of the [SNS]H 3 scaffold through the synthesis and reactivity of a novel set of square-planar nickel complexes.Chapters 2 and 3 describe a modular synthetic approach towards generating a new series of heterobimetallic complexes with the general formula W[SNS]2M(L) ([SNS] = bis(2-mercapto- p-tolyl)amine; M = Ni, Pd, or Pt; and L = dppe, depe, dmpe, dppp, PR'2NRPR'2 (R = phenyl, benzyl; R'=phenyl), DPEphos or dppf). The complexes were prepared by a salt metathesis of Cl2MII(L) with the previously reported W[SNS]2 coordination complex under reducing conditions. X-ray diffraction analysis revealed interesting coordination geometries about the appended Group 10 metal centers moving from Pt and Pd (pseudo-square planar) to the first row Ni (pseudo-tetrahedral) analogue. These complexes demonstrate formal metal--metal bond formation across the series with a tunable first oxidation potential up to 600 mV.Chapter 4 investigates the use of W[SNS]2Ni(dppe) as a catalyst for the electrochemical reduction of protons to hydrogen. This complex was found to catalytically generate hydrogen with an overpotential of 700 mV, a TOF of 14 sec--1, and a Faradaic yield of 80 +/- 3 % using 4-cyanoanilinium tetrafluoroborate in non-aqueous solutions.Chapter 5 demonstrates the effect of exchanging the nickel center of the heterobimetallic complexes discussed in Chapters 2 and 3 with other first row transitions metal ions (i.e. cobalt and copper). Analysis into the observed metal--metal distances reveal stark differences across the series. Additionally, the copper ion containing complexes demonstrate dynamic behavior in solution.Chapter 6 investigates the synthesis and reactivity of a series of monomeric square-planar nickel complexes of the [SNS] scaffold to demonstrate the ligand as redox, proton, and hydrogen atom non-innocent.Appendix A illustrates the electrochemical responses observed for the monoanionic complexes from Chapter 6 in the presence of CO2 and CO. Appendices B and C describe the synthesis and characterization of a five-coordinate cobalt and a heterotrimetallic tungsten-nickel complex, respectively.

Book Synopsis Group 13 Chemistry by : Pamela J. Shapiro
Download or read book Group 13 Chemistry written by Pamela J. Shapiro and published by . This book was released on 2002 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Group 13 Chemistry: From Fundamentals to Applications contains research reports and review articles in both the fundamental and applied aspects of group 13 chemistry. Topics covered illustrate the widespread influence of group 13 chemistry in modern science and technology. This volume addresses recent research and technological achievements involving group 13 chemistry and provides important background information for both experienced practitioners and novices. New developments in group 13 compounds, the stabilization of compounds of the lighter group 13 elements in their +1 oxidation state, and electron-deficient group 13 clusters, are presented. Because of the unusual geometries of newly developed electron-deficient group 13 clusters, chemists have had to reexamine and refine their models of structure and bonding. Furthermore, the stabilization of compounds of the lighter group 13 elements in their +1 oxidation state has produced some unique molecular structures and reactivity. Group 13 compounds are well known as reagents for organic synthesis and as both catalysts and cocatalysts for asymmetric organic transformations and alkene and ring-opening polymerization. Now, the design of multidentate Lewis acids is expected to exhibit enhanced activity via the cooperation of multiple electrophilic sites. Finally, a special section devoted to aluminum chemistry examines the environmental sources and biological effects of this most abundant metal. Research implicating aluminum in the etiology of neurological diseases is examined as well as potentially useful biochemical applications for aluminum in the form of Al4-.

Book Synopsis Surface Organometallic Chemistry: Molecular Approaches to Surface Catalysis by : Jean-Marie Basset
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.

Book Synopsis Late Transition Metal Polymerization Catalysis by : Bernhard Rieger
Download or read book Late Transition Metal Polymerization Catalysis written by Bernhard Rieger and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the start of the 1950s, Ziegler and Natta discovered that simple metallorganic catalysts are capable of transforming olefins into linear polymers with highly ordered structures. This pioneering discovery was recognized with a Nobel Prize in 1963. In the 80s and 90s, the development of molecular defined metallocenes led to a renaissance for non-polar polyolefin materials. Designer catalysts allowed a greater precision in defining properties of the material. The past 10 years have seen the discovery of new catalysts based on late transition metals, which allow the combination of polar monomers with non-polar olefins and thus lead to innovative materials. Here, the world's leading authors from industry and academia describe the latest developments in this fascinating field for the first time in such comprehensive detail. In so doing, they introduce readers systematically to the basic principles and show how these new catalysts can effectively be used for polymerization reactions. This makes the book an ideal and indispensable reference for specialists, advanced students, and scientists of various disciplines dealing with research into catalysts and materials science.
