Solvolyses of monosubstituted benzhydryl bromides gave excellent linear correlations of logk with sigma + constants, and not with Y(BnBr) or Y(Br). Correlation analyses against corresponding logk of d-tert-butyl-(2-naphthyl)methyl bromide provided evidence for the importance of different extent of solvation in delocalized transition state and for nucleophilic solvent intervention in the solvolysis of benzhydryl systems.
