The Baeyer-Villiger oxidation of exo-7-acetyl[4.2.1]- and exo-7-acetyl[4.2.2]propellanes (2X) and (3X) mainly proceeds via unusual carboration intermediates to afford the rearranged products.

The synthesis of bicyclo[n, 2.2]bridgehead alkenes (2a) and (2b) by the solvolytic rearrangement of the corresponding tricyclic acetates (3a) and (3b) in aceticacid and the electrophilic addition of aceticacid to anti-Bredt olefin (2a) are described.
Product study and kinetic data of the solvolysis of the bridgehead chlorides () and ( indicate the neighboring group participation of the strainedbridgeheaddoublebonds.
