Thermal electrocyclization reactions II: benzooctatetraenes and benzodecapentaenes
Thermal electrocyclization reactions of benzooctatetraenes and benzodecapentaenes substituted with R¼H, Cl, and methyl were studied experimentally and computationally. Methyl and unsubstituted benzooctatetraenes and benzodecapentaenes give the [4.2.0]bicyclooctadiene products by 8p, 6p- electrocyclization. Chlorine substitution led to thermal rearrangement of the initially formed 8p, 6p-electrocyclization intermediates to give unprecedented products.
