(o‐Alkylbenzoyl)phosphonates readily cyclize to highly strained benzocyclobutenols simply upon irradiation with UV light. The remarkable efficiency is ascribed to the electron‐accepting character of the phosphonate substituent, which facilitates thermal ring closing of the o‐quinodimethane intermediate and suppresses reversion to the starting carbonyl compound.
