Download or read book Ab Initio Study of the Thermal Isomerization of Small Strained Cyclic Hydrocarbons written by Zhendong Zhao and published by . This book was released on 2010 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermal isomerizations of several small highly strained polycyclic hydrocarbons were studied using ab intitio methods at the multiconfiguration self-consistent field level. The lowest-energy pathway for the thermolysis of tricyclo- [4.1.0.02,7 ]heptene proceeds through the intermediate (E,Z,Z)-1,3,5-cyclohepta-tri-ene with an activation barrier of 31.3 kcal · mol-1 . The intermediate can then isomerize via two pathways to give bicyclo[3.2.01hepta-2,6-diene through an electrocyclic ring closure with a barrier of 11.1 kcal · mol -1 or (Z,Z,Z)-1,3,5- cycloheptatriene through a trans double bond rotation with a barrier of 16.1 kcal · mol-1 . The thermolysis of bicyclo[3.2.0]hepta-2,6-diene via a conrotatory pathway to give (E,Z,Z)-1,3,5-cycloheptatriene has a barrier of 30.5 kcal · mol-1 . The lowest-energy pathway for the thermal isomerization of tetracyclo[4.1.0.024 .- 03,5 ]heptane proceeds through the intermediate cis-trans-norcaradiene with a barrier of 37.4 kcal mol-1 . The intermediate rearranges to cis-cis-norcaradiene through a trans double bond rotation with a low barrier of only 1.4 kcal · mol-1 . The lowest-energy pathway for the thermolysis of 2-aza-tricyclo[3.1.0.02,6 ]hexane proceeds through intermediate (E,Z)-1,3-pyridine with an activation energy of 30.1 kcal · mol-1 which then isomerizes via a trans double bond rotation with a low barrier of 4.3 kcal · mol-1 . The methyl substituent effects on the conrotatory isomerization of bicyclo[3.2.0]hepta-2,6-diene were also studied. The methyl sbustituent favors the "outward" rotation; the "outward" rotation of a methyl substituent is about 2.5 kcal · mol -1 lower than the "inward" rotation.

Download or read book Polynuclear Aromatic Compounds written by Lawrence B. Ebert and published by . This book was released on 1988 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents accounts of current research in polynuclear aromatic compounds, showing examples of studies both of pure compounds and of complex, fossil fuel related mixtures. Offers a thorough knowledge of aromatic chemistry through coverage of reduction, oxidation, and thermal reactions--including applications developed for both coal and petroleum materials. Featured topics include quantum chemical structure-reactivity relationships, spatial configurations of large polynuclear hydrocarbons, cyclophanes, and desulfurization of heterocycles. Scientists studying all aspects of the chemistry of polynuclear aromatics will discover important, pertinent information in this volume.
