  • Aromatic Or Antiaromatic?
    10322 J. Am. Chem. Soc. 2001, 123, 10322-10328 Butalene and Related Compounds: Aromatic or Antiaromatic? Philip M. Warner* and Graham B. Jones* Contribution from the Department of Chemistry, Northeastern UniVersity, Boston, Massachusetts 02115 ReceiVed May 7, 2001 Abstract: Density functional theory (DFT) has been used to study the first three members of the condensed cyclobutadienoid series, butalene (3), bicyclobutadienylene (12), and dicyclobutenobutalene (20). The first is planar and is judged “aromatic” by comparisons with suitable models using both energetic and magnetic criteria. The second is nonplanar, and not aromatic, but not so antiaromatic as cyclobutadiene (11). The third is slightly more antiaromatic and best viewed as a butalene fused to two cyclobutadiene rings; its properties are the sum of aromatic and antiaromatic components, like benzocyclobutadiene. Ring-opening transition states for both 3 and 12 have been located, and these are conrotatorily twisted. The ring-opening barrier for 12 is more than twice that for 3. Ring-opening of 20 involves ring inversion as the only barrier. Introduction The Bergman rearrangement of enediynes to p-benzynes (e.g., 1 to 2) continues to receive experimental and theoretical attention.1 The possibility that butalene (3), a “valence isomer” of 2, could have an independent existence was recognized over 25 years ago, when it was introduced as a theoretical species less stable than 2 and insulated from conversion to 2 by a 4.6 kcal/mol barrier (MINDO 3).2,3 The Breslow lab has reported experimental results implicating 3 as an intermediate.4,5 Briefly summarized, chloro-Dewar benzene 4 was treated with strong base to afford, in the presence of diphenylisobenzofuran, 10- 15% of amino-Dewar benzene adduct 6.

  • Modern Valence-Bond Descriptions of Polycyclic Fused Aromatic Compounds Involving Cyclopropenyl Rings
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by University of Liverpool Repository Modern Valence-Bond Descriptions of Polycyclic Fused Aromatic Compounds Involving Cyclopropenyl Rings a, b, Peter B. Karadakov and David L. Cooper aDepartment of Chemistry, University of York, Heslington, York, YO10 5DD, U.K. b Department of Chemistry, University of Liverpool, Liverpool L69 7ZD, U.K. Abstract The feasibilities and electronic structures of five ten--electron fused conjugated molecules involv- ing cyclopropenyl rings are explored using second-order Møller-Plesset perturbation theory (MP2), spin-coupled (SC) and complete-active-space self-consistent-field (CASSCF) wavefunctions, in the cc-pVTZ basis. All five fused conjugated molecules are predicted to have rigid planar ground state geometries of C2v or D2h symmetry and large dipole moments (if not of D2h symmetry). The com- pact ground state SC(10) wavefunctions with ten active orbitals for these molecules are found to be of comparable quality to the respective CASSCF(10,10) constructions, but much easier to interpret. The analyses of the ground state SC(10) wavefunctions for all five fused conjugated molecules re- veal resonance patterns which indicate that all of these molecules are aromatic in their electronic ground states; on the other hand, the SC(10) approximations to the first singlet electronic excited states are found to exhibit “antiresonance” which suggests that each of the five molecules switches from aromatic to antiaromatic upon vertical excitation from the ground state to its first singlet excited state. Ring strain prevents the formation of a fused structure involving three cyclopropenyl rings and a cycloheptatrienyl ring; the alternative stable dehydro compound which resembles m-benzyne is shown, using a SC(12) wavefunction, to involve a weak bond between the dehydro centres.

  • Quantitative Studies on Aromaticity and Antiaromaticity
    QUANTITATIVE STUDIES ON AROMATICITY AND ANTIAROMATICITY RONALD BRESLOW Department of Chemistry, Columbia University, New York, N.Y. 10027, USA ABSTRACT The properties of the simplest aromatic compound, are fully consistent with expectations. Spectroscopic studies show that it is a symmetric cation with approximately the stability expected from simple quantum mechanical con- siderations. Various studies on cyclopropenyl anions reveal that they are undoubtedly resonance destabilized. Thus, the kinetic studies which have been done on rates of hydrogen exchange in this system can be shown to be consistent only with electronic destabilization in the antiaromatic cyclopropenyl anion. Direct thermodynamic determinations of the stability of cyclopropenyl anions can also be performed using a novel electrochemical procedure, and using this method very high PKaS are found for some of these anions, indicating great stability. Resonance destabilization in cyclobutadiene can also be demon- strated by examining the basicity of a cyclobutadienocyclopentadiene anion and also by electrochemical studies on a fused naphthalenecyclobutadiene derivative. 1-Chloro-bicyclo{2,2,O]hexadiene has been prepared. On treatment with strong base it apparently eliminates HC1 to generate transient butalene (cyclobutadienocyclobutadiene) which is then trapped by the medium. Since the first synthesis of a cyclopropenyl cation, the triphenyl derivative synthesized in 19671, work in our laboratory and in a number of others has been devoted to a study o this simplest aromatic system. Of course, the description of the cyclopropenyl cation ring as 'aromatic' involves some assumptions about a definition of the term aromaticity, and I would like to focus first on this problem. There are a number of things which are special about the compounds which have been called aromatic, but the one which is certainly at the root of most of their unusual properties concerns their energies.

    Exploring the validity of the Glidewell- Lloyd extension of Clar’s -sextet rule. Assessment from polycyclic conjugated hydrocarbons† Ouissam El Bakouria, Jordi Poaterb,c, Ferran Feixasa and Miquel Solà*,a a Institut de Química Computacional i Catàlisi (IQCC) and Departament de Química, Universitat de Girona, Campus Montilivi, 17071 Girona, Spain. E-mail: [email protected] b Departament de Química Inorgànica i Orgànica & Institut de Química Teòrica i Computacional (IQTCUB), Universitat de Barcelona, Martí i Franquès 1-11, 08028 Barcelona, Catalonia, Spain. c Institució Catalana de Recerca i Estudis Avançats (ICREA), Pg. Lluís Companys 23, 08010 Barcelona, Catalonia, Spain Abstract The Clar -sextet rule was formulated as a tool to qualitatively assign the local aromatic character of six-membered rings in benzenoid species. This simple rule has been widely validated both experimentally and theoretically. In 1984, Glidewell and Lloyd reported an extension of this rule to polycyclic conjugated hydrocarbons having rings with any even number of carbon atoms in their structure. In this work, we assess the validity of the Glidewell-Lloyd extension in 69 polycyclic conjugated hydrocarbons composed of different combinations of four-, six-, and eight-membered rings. Our results support the validity of this extension with some exceptions that are discussed. Finally, a minor modification to the rule is proposed. Keywords: Glidewell-Lloyd’s rule · Clar’s -sextet rule · Polycyclic conjugated hydrocarbons · Aromaticity · Clamped benzenes · double bonds in ring junctions † This work is dedicated to Prof. Dr. Alberto Vela as a proof of our admiration for his brilliant contributions to chemistry 1 Introduction The renowned Hückel 4n+2 -electron rule [1-4] states that monocyclic conjugated hydrocarbons (annulenes) of DNh symmetry with 4n+2 π-electrons are aromatic.

  • Steam, the Necessity of the Safety Device Became Evident
    Introduction to Safety Valves Introduction As soon as mankind was able to boil water to create steam, the necessity of the safety device became evident. As long as 2000 years ago, the Chinese were using cauldrons with hinged lids to allow (relatively) safer production of steam. At the beginning of the 14th century, chemists used conical plugs and later, compressed springs to act as safety devices on pressurised vessels. Early in the 19th century, boiler explosions on ships and locomotives frequently resulted from faulty safety devices, which led to the development of the first safety relief valves. In 1848, Charles Retchie invented the accumulation chamber, which increases the compression surface within the safety valve allowing it to open rapidly within a narrow overpressure margin. Today, most steam users are compelled by local health and safety regulations to ensure that their plant and processes incorporate safety devices and precautions, which ensure that dangerous conditions are prevented. The primary function of a safety valve is therefore to protect life and property. The principle type of device used to prevent overpressure in plant is the safety or safety relief valve. The safety valve operates by releasing a volume of fluid from within the plant when a predetermined maximum pressure is reached, thereby reducing the excess pressure in a safe manner. As the safety valve may be the only remaining device to prevent catastrophic failure under overpressure conditions, it is important that any such device is capable of operating at all times and under all possible conditions. Safety valves should be installed wherever the maximum allowable working pressure (MAWP) of a system or pressure-containing vessel is likely to be exceeded.
