p-toluenesulfonate 11a lower their solvolysisrates in 80% EtOH by factors of 28 and 16, respectively. A spirocyclopropyl group including C(6), as in 21a and 22a, reduces the rate of exo- and endo-ionization by factors of 250 and 8, respectively. The geminally dimethyl-substituted tosylates 10a and 11a yield the 2-exo-alcohol 10b, whereas the spirocyclopropyl-substituted tosylates 21a and 22a furnish rearranged
