dienophiles triazolinedione, singlet oxygen and in part tetracyanoethylene cyclo-add to bicyclo[2.1.0]pent-2-ene (1) across the central σ-bond to give bicyclo[2.2.1]heptene-type adducts, while the dipoles phenyl azide, benzonitrile oxide and diphenyldiazomethane cyclo-add at the π-bond with expected stereochemistry.
