Reaction of endo-tricyclo [3.2. 1.02~ 4] octane (1) with deuteron in methanol-dl gave a mixture (62: 38) of methoxy ethers 3b and 4b from cleavage of the most substituted cyclopropane bond. The reaction proceeds by attack of deuterium at the corner of the cyclopropane. Trapping of the intermediate cation 5b is competitive with rearrangement to the nonclassical cation 6b. Reaction of exo-tricycle [3.2. 1.02 v4] octane (2) under similar ...
