Abstract
To verify the Taft σ* values, data from several reaction series were fitted to the equation log k=ρ*σ*+ log k0. The calculated σ* values were in good agreement with each other, but certain substituents, especially hydrogen, behave differently in some reaction series. On the basis of the σ*(CCl3) values obtained from the different reaction series, it is concluded that the acid-catalysed esterification of trichloroacetic acid in an alcohol solution takes place by the normal AAC2 mechanism, although the acid-catalysed hydrolysis of ethyl trichloroacetate in aqueous solutions mainly proceeds by the exceptional A–BAC3 mechanism. In the case of simultaneous reactions, the Ingold–Taft equation can be employed to estimate the contribution of the normal AAC2 mechanism.
