    Description / Table of Contents: Norpinyl-Norbornyl Rearrangements: Resonance-Stabilized Bicyclo[3.l.l]hept-2-yl Cations2-Phenylbicyclo[3.1.1]hept-2-yl cations (5c), generated by solvolysis of the 4-nitrobenzoate 8, undergo norpinyl-norbornyl rearrangement to a minor extent (〈 6% in water, 〈1% in methanol). The acid-catalyzed alkoxy exchange of 2,2-dimethoxybicyclo[3.1.1]heptane (13) proceeds without skeletal rearrangement. The solvolysis of bicyclo[3.1.1]hept-3-en-2-yl-4-nitrobenzoate (19) is complicated by O-acyl cleavage but the hydrolysis of the allylic bromide 21 and the nitrous acid deamination of the corresponding amine give bicyclo[3.1.1]hept-3-en-2-ol (18) exclusively.
    Notes: 2-Phenylbicyclo[3.1.1]hept-2-ylkationen (5c), erzeugt durch Solvolyse des 4-Nitrobenzoats 8, zeigen Norpinyl-Norbornyl-Umlagerung in geringem Ausmaß (〈 6% in Wasser, 〈 1% in Methanol). Der säurekatalysierte Alkoxy-Austausch in 2,2-Dimethoxybicyclo[3.1.1]heptan (13) verläft ohne Gerüstumlagerung. Die Solvolyse von Bicyclo[3.1.1]hept-3-en-2-yl-4-nitrobenzoat (19) wird durch O-Acyl-Spaltung kompliziert, jedoch ergeben die Hydrolyse des Allylbromids 21 und die Desaminierung des entsprechenden Amins 24, ausschließlich Bicyclo[3.1.1]hept-3-en-2-ol (18).
