High impact information on cyclooctatetraene

  • The porphyrin sheet 3 forms stable 1:2 complexes with guest molecules G1 and G2, whose 1H NMR spectra exhibit remarkable downfield shifts for the guest protons that are located just above the cyclooctatetraene (COT) core of 3, whereas the imidazolyl protons bound to the zinc(II) porphyrin local cores are observed at slightly upfield positions [1].
  • Density functional theory study of redox pairs: 2. Influence of solvation and ion-pair formation on the redox behavior of cyclooctatetraene and nitrobenzene [2].
  • In the case of 14, the ring-opening reaction (E(A) = 27.2 kcal/mol) is concerted and leads directly to 15, a 4-fold bridged cyclooctatetraene [3].
  • A novel cyclooctatetraene (COT) radical cation fully annelated with bicyclo[2.1.1]hexene units was prepared as SbCl(6)(-) salt, and planarity of the octagonal ring was clarified by ESR and theoretical calculations [4].
  • A pericyclic mechanism involving dimerization of C4H4 metallocycles is proposed to account for the formation of cyclooctatetraene [5].
