The solvolysis rates of cyclopropyl(trifluoromethyl)carbinyl tosylate (1) have been determined in a series of aqueous alcohol, aqueous trifluoroethanol, and carboxylic acid solvents. Analysis of the rate data for % internal-return isomerization and salt effects and correlation with Y(OTs) values indicates that 1 underwent solvolysis by the k-DELTA pathway. Comparison of the relative ability [k(c-Pr)/k(Ph)] of cyclopropyl and phenyl groups to stabilize carbocation-like transition states in solvolysis reactions of the secondary systems RCH(Y)CH3 and RCH(Y)CF3 reveals that replacement of phenyl with cyclopropyl increases the rate in both systems by a factor of 10(2).
