Phase 2, 5-Pentadienyl system

By analogy with the categories of pericyclic reactions we have already considered, the feasibility of the migration will then be decided by the relative phase of the terminal lobes, i.e. the symmetry, of the HOMO of the pentadienyl radical (38). As this is a 5ne system, its... [Pg.352]

Pentadienyl cations can undergo electrocyclization to cyclopentenyl cations. As this is a four Tt-electron system, it should occur by conrotation. Based on gas phase ion stability data, the reaction is exothermic by 18 kcal/mol. ... [Pg.908]
