Facile o-quinodimethane formation from benzocyclobutenes triggered by the Staudinger reaction at ambient temperature

Electron-donating iminophosphoranes were found to significantly enhance 4π-ring opening of benzocyclobutenes to generate o-quinodimethanes at 20-25 °C. These iminophosphorane benzocyclobutenes can be conveniently generated from azide benzocyclobutenes and phosphines via the Staudinger reaction. Thus...
