Abstract
Kinetics of the reactions of nine symmetrically substituted 1, 3-diarylallyl cations with different nucleophiles were studied photometrically in dichloromethane, acetonitrile, and DMSO solutions. The second-order rate constants k 2 were found to follow the correlation log k 2= s N (N+ E). The electrophilicity parameters E of the title cations were derived, using the known values of s N and N of the nucleophilic reaction partners, and compared with ...
