all-trans-1,2,3,4,5-pentamethylcyclopentyl cation have been developed. These cations both undergo very rapid multiple 1,2-hydrideshifts, but the rate of this process is about 40 times faster in the all-trans case. This implies that the stereochemistry of the penultimate hydride in the rearrangement cascade can affect the rate of a given 1,2-hydrideshift, i.e. that it is better if this penultimate
