Bent Bonds and the Antiperiplanar Hypothesis. A Model to Account for Sigmatropic [1,n]-Hydrogen Shifts Sigmatropic hydrogen shifts are rationalized using the BBAH involving antiperiplanar displacement of radical intermediates. The stereochemistry of both thermal and photochemical […]
High Temperature Isomerization of Benzenoid Polycyclic Aromatic Hydrocarbons. An Analysis through the Bent Bond and Antiperiplanar Hypothesis Orbital Model. The properties and stereochemical reactivity of cyclobutadiene, benzene, cyclooctatetraene and the [10]- to [14]annulenes can be […]
Bent Bonds (τ) and the Antiperiplanar Hypothesis – the Chemistry of Cyclooctatetraene and other C8H8Isomers The fascinating chemistry of cyclooctatraene, including its propensity for ring inversion, bond shifting, and valence isomerization, is analyzed by the […]
