Abstract
Long live the carbene: Longevity is granted to fluorophenoxycarbene when it is generated photochemically from fluorophenoxydiazirine (see picture) inside a hemicarcerand. This fleeting, and otherwise nonisolable, singlet carbene is the first electron-deficient species that has been stabilized by trapping. NOE experiments suggest that the carbene adopts the intrinsically less stable cis conformation in the confined inner phase. (Chemical Equation Presented).
