Abstracts International Symposium on Relations between Homogeneous and Heterogeneous Catalysis July 16-20, 2007 Gabor Somorjai, Ed. University of California, Berkeley, CA Preface The International Symposium on Relations between Homogeneous and Heterogeneous Catalysis (ISHHC) has a long and distinguished history. Since 1974, in Brussels, this event has been held in Lyon, France (1977), Gr¨oningen, The Netherlands (1981); Asilomar, California (1983); Novosibirsk, Russia (1986); Pisa, Italy (1989); Tokyo, Japan (1992); Balatonf¨ured, Hungary (1995); Southampton, United Kingdom (1999); Lyon, France (2001); Evanston, Illinois (2001) and Florence, Italy (2005). The aim of this international conference in Berkeley is to bring together practitioners in the three fields of catalysis, heterogeneous, homogeneous and enzyme, which utilize mostly nanosize particles. Recent advances in instrumentation, synthesis and reaction studies permit the nanoscale characterization of the catalyst systems, often for the same reaction, under similar experimental conditions. It is hoped that this circumstance will permit the development of correlations of these three different fields of catalysis on the molecular level. To further this goal we aim to uncover and focus on common concepts that emerge from nanoscale studies of structures and dynamics of the three types of catalysts. Another area of focus that will be addressed is the impact on and correlation of nanosciences with catal- ysis. There is information on the electronic and atomic structures of nanoparticles and their dynamics that should have importance in catalyst design and catalytic activity and selectivity. There are over 300 attendees registered for this meeting attesting to the vitality of these fields of sci- ence. We look forward to making your visit in Berkeley enjoyable as well as scientifically rewarding. Gabor A.

  • (Title of the Thesis)*
    FLUOROCARBENE, FLUOROALKYL, AND FLUORIDE COMPLEXES OF FIRST-ROW TRANSITION METALS Graham Mark Lee Thesis submitted to the Faculty of Graduate and Postdoctoral Studies University of Ottawa In partial fulfillment of the requirements for the degree of Doctor of Philosophy Ottawa-Carleton Chemistry Institute Faculty of Science University of Ottawa © Graham Mark Lee, Ottawa, Canada, 2017 Abstract Fluorinated organic compounds play important roles in our society, as these products range from life-saving pharmaceuticals and agrochemicals, to fluoropolymers with extremely high thermal and chemical stability. Although elemental fluorine (F2) is the most reactive element, some fluoro- organic compounds are chemically inert. As such, controlled reactivity of fluorine or highly- fluorinated organic fragments is a considerable, yet important challenge for synthetic chemists. Fluoro-organometallic chemistry has been studied for decades, as researchers attempt to maximize the potential of metal mediated/catalyzed processes for the synthesis of fluorinated organic molecules. Within this framework, metal fluorocarbene complexes are particularly interesting because of their highly tunable reactivity, and are proposed for use in important metathesis/polymerization reactions of perfluorinated alkenes. While considerable work is still needed to make these proposed reactions a reality, this thesis outlines contributions from our F F research group. We showed that cobalt fluorocarbene complexes CpCo(=CFR )(PPh2Me) (R = F, CF3) undergo [2+2] cycloaddition reactions with tetrafluoroethylene (TFE) and phenylacetylene to form perfluorometallacyclobutane and partially fluorinated metallacyclobutene products, respectively. For both reactions, computational studies reveal a stepwise ring-closing mechanism, which proceeds through a singlet 1,4-diradical intermediate. Next, the formation of CpCo(=CF2)(L) complexes is achieved via the direct addition of difluorocarbene, generated in situ, to a cobalt(I) precursor.

  • Polytetrafluoroethylene: Synthesis and Characterization of the Original Extreme Polymer
    Polytetrafluoroethylene: Synthesis and Characterization of the Original Extreme Polymer Gerard J. Putsa, Philip Crousea and Bruno M. Amedurib* aDepartment of Chemical Engineering, University of Pretoria, Pretoria 0002, South Africa. b Ingenierie et Architectures Macromoléculaires, Institut Charles Gerhardt, UMR 5253 CNRS, UM, ENSCM, Place Eugène Bataillon, 34095 Montpellier Cedex 5, France. Correspondence to: Bruno Ameduri (E-mail: [email protected]) 1 ABSTRACT This review aims to be a comprehensive, authoritative, and critical review of general interest to the chemistry community (both academia and industry) as it contains an extensive overview of all published data on the homopolymerization of tetrafluoroethylene (TFE), detailing the TFE homopolymerization process and the resulting chemical and physical properties. Several reviews and encyclopedia chapters on the properties and applications of fluoropolymers in general have been published, including various reviews that extensively report copolymers of TFE (listed below). Despite this, a thorough review of the specific methods of synthesis of the homopolymer, and the relationships between synthesis conditions and the physico-chemical properties of the material prepared, has not been available. This review intends to fill that gap. As known, PTFE and its marginally modified derivatives comprise some 6065 % of the total international fluoropolymer market with a global increase of ca. 7 % per annum of its production. Numerous companies, such as Asahi Glass, Solvay Specialty Polymers, Daikin, DuPont/Chemours, Juhua, 3F and 3M/Dyneon, etc., produce TFE homopolymers. Such polymers, both high molecular-mass materials and waxes, are chemically inert, hydrophobic, and exhibit an excellent thermal stability as well as an exceptionally low co-efficient of friction. These polymers find use in applications ranging from coatings and lubrication to pyrotechnics, and an extensive industry (electronic, aerospace, wires and cables, as well as textiles) has been built around them.

  • Environmental Property Modeling of Perfluorodecalin and Its Implications for Environmental Fate and Hazards
    Aerosol and Air Quality Research, 11: 903–907, 2011 Copyright © Taiwan Association for Aerosol Research ISSN: 1680-8584 print / 2071-1409 online doi: 10.4209/aaqr.2010.12.0106 Environmental Property Modeling of Perfluorodecalin and its Implications for Environmental Fate and Hazards Wen-Tien Tsai* Graduate Institute of Bioresources, National Pingtung University of Science and Technology, Pingtung 912, Taiwan ABSTRACT In a variety of medical and industrial uses, small amounts of perfluorodecalin (C10F18) may have been released into the environment. However, it may significantly contribute to the global warming due to its highly radiative efficiency and global warming potential (GWP). Using the chemical similarity approach, this article aimed at calculating the fate properties and discussing the environmental implications of the perfluorinated compound for the purpose of mitigating its emissions. The environmental fate properties of perfluorodecalin, including octanol-water partition coefficient, water solubility and Henry’s law constant, were first estimated in the present study. These predicted values were further compared with those of other chemically similar compounds such as naphthalene, decalin and decane. From the computational findings, perfluorodecalin, which has exceptionally low solubility in water and high vaporization from the water bodies, tends to be hydrophobic and partitioned into organic matter, suggesting that it will sink into the atmosphere. Also addressed in the paper was a possible proposal for forming trifluoroacetic
