    was found to compete with intramolecular addition to the double bonds. The product distributions are strongly affected by triplet sensitization, in contrast to those of analogous intermolecular reactions. The singlet and triplet components of the intramolecular processes were dissected and evaluated in terms of k S /k ST and k T /k TS rate ratios.

  • The effect of the benzene ring on 1,5-electrocyclizations: Synthesis and thermolysis of optically active benzohomofuran, benzohomothiophene, N-carbmethoxyhomoindole, benzohomophosphole and homoindene.
    作者:Frank-Gerrit Klärner、Annette E. Kleine、Dirk Oebels、Friedrich Scheidt

    日期:1993.3
    Carbonyl ylide-like intermediates are involved in the 1,5-electrocyclization of the benzo-heterocycles 3a-d mentioned in the title. The activation barriers analyzed by the time- and temperature-dependence of the racemisation of the optically active derivatives turned out to be higher by DELTADELTAG(not-equal) = 13 +/- 2 kcal/mol than those determined for the parent systems 1a-d whereas for the corresponding carbocycles 3d and 1d the difference is only DELTADELTAG(not-equal) almost-equal-to 4 kcal/mol as expected from the difference between the bond dissociation energies of toluene and propene (DELTABDE = 3.2 kcal/mol). This result can be considered as an evidence for the electrocyclic character of the ring-opening in the heterocycles 1a-d and 3a-d. The difference between the Gibbs activation enthalpies found for the ring-opening of homofuran 1a and homothiophene 1b (DELTADELTAG(not-equal) = 8.7 kcal/mol) can be attributed to the heteroatom effect on the ground state.
