Reactivity and Functionalization of Naphthalene and Anthracene Complexes of {Tpw(NO)(Pme3)}
Reactivity and Functionalization of Naphthalene and Anthracene Complexes of {TpW(NO)(PMe3)} Laura Jessica Strausberg Baltimore, Maryland B.A., Hollins University, 2008 A Dissertation presented to the Graduate Faculty of the University of Virginia in Candidacy for the Degree of Doctor of Philosophy Department of Chemistry University of Virginia July, 2013 ii Abstract Chapter 1 introduces the organic chemistry of aromatic hydrocarbons, with attention paid to regiochemical outcomes of organic reactions. The binding of naphthalene and anthracene to metal complexes is discussed, along with organic transformations they undergo as a result of their complexation. The previous work on osmium and rhenium complexes of naphthalene from the Harman group is explored. Finally, some spectroscopic techniques for exploring the chemistry of {TpW(NO)(PMe3)} complexes of naphthalene and anthracene are introduced. Chapter 2 discusses the highly distorted allyl complexes formed from {TpW(NO)(PMe3)} and the exploration of their origin. Attempts at stereoselectively deprotonating these cationic complexes is also discussed. 2 Chapter 3 describes our study of TpW(NO)(PMe3)(3,4-η -naphthalene)’s ability to undergo a Diels-Alder reaction with N-methylmaleimide. A solvent study suggested that this reaction proceeds by a concerted mechanism. To probe the mechanism further, we synthesized a series of methylated and methoxylated naphthalene complexes and measured their rates of reaction with N-methylmaleimide compared to the parent complex. We found that 1- substitution on the naphthalene increased the rate of cycloaddition, even if the substituent was in the unbound ring, while 2-substitution slowed the reaction rate when in the bound ring. This information is consistent with a concerted mechanism, as a 2-substituted product would be less able to isomerize to form the active isomer for the cycloaddition to occur. -

Chapter 16 Liquid and Solids
Homework #2 Chapter 16 Liquid and Solids 7. Vapor Pressure: The pressure exerted by the vapor of a liquid when the vapor and the liquid are in dynamic equilibrium. The vapor pressure reflects the fact that within a system there is a distribution of energies that molecules can have, therefore, some molecules will have enough energy to overcome the intermolecular forces and enter into the gas phase. All liquids have some vapor pressure. The stronger the intermolecular forces the smaller the vapor pressure. All solids also have a vapor pressure. This is why if you leave ice in the freezer for a long time it “disappears.” The vapor pressure of solids is less than the vapor pressure of liquids. As the temperature increases the molecules have more energy, therefore, more molecules can escape into the gas phase (vapor pressure increases). When the vapor pressure is equal to the atmospheric pressure the solution boils. 9. a) Surface Tension As the intermolecular forces increase (↑), surface tension increases (↑). b) Viscosity As the intermolecular forces increase (↑), the viscosity increases (↑). c) Melting Point As the intermolecular forces increase (↑), the melting point increases (↑). d) Boiling Point As the intermolecular forces increase (↑), the boiling point increases (↑). e) Vapor Pressure As the intermolecular forces increase (↑), the vapor pressure decreases (↓). 11. Intermolecular Forces: The forces of attraction/repulsion between molecules. Intramolecular Forces: The forces of attraction/repulsion within a molecule. Intramolecular forces are stronger the intermolecular forces. Types of intermolecular forces: Dipole-Dipole Forces: The interaction between two electric dipoles in different molecules. Hydrogen Bonding: The attraction between a hydrogen atom (that is bonded to an O, N, or F atom) and an O, N, or F atom in a neighboring molecule. -
