The kinetics of the alkaline hydrolysis of a series of subtituted 4-dimethylamino-4'-methoxytriphenylcarbonium ions in water were studied by a spectrophotometric method.The activation parameters of the process were determined.Within the limits of the investigated reaction series there are two isokinetic temperatures, i.e., for donor and acceptor substituents, and accordingly various types of reactivity control.As a result of this the Hammett plots contain an inflection, the degree of which decreases with increase in temperature.The reactivity of the investigated cations with respect to water is practically independent of the substituent.
