Popis: A significant acceleration effect of a β-silicon atom was observed on the electrocyclic ring-opening reaction of benzocyclobutene derivatives to form o-quinodimethanes. This acceleration effect could be attributed to an electronic σ-donating nature of the C(α)−Si(β) bond, associated with α-anion driven pericyclic reactions.
