Parole denied : Fluoro(phenoxy)carbene persists for days if generated inside the cavity of a hemicarcerand. Elusive products of carbene rearrangements, such as cycloheptatetraenes and bridgehead alkenes, have also been stabilized by incarceration. Carbenes attack hemicarcerand hosts less readily than cyclodextrins whose hydroxy groups are the preferred sites of reaction.
