The solvolysis rates of p-(cis-or trans-2-substituted cyclopropyl)-α-methylbenzyl chlorides including electron-donating and electron-attracting substituents relative to a hydrogen substituent were measured in 80% aqueous acetone. The trans isomers were more reactive than the corresponding cis derivatives where cyclopropyl and phenyl groups could not get a most favorable “bisected” conformation for the cyclopropyl group to release electrons to ...
