The rates of reactions of several substituted trans-cinnamate and acrylate ions with ethyl bromoacetate in 90percent acetone-10percent water (v/v) have been measured at 303, 308 and 313 K.A good Hammett correlation is obtained for trans-cinnamate ions with ρ = -0.181 at 308 K.Correlation with non-aromatic trans-3-substituted acrylate ions is poor.There is an apparent failure of reactivity-selectivity principle in this case possibly due to a slightly modified transition state.
