摘要

In aqueous solution, Girard T hydrazone formation from para-substituted benzaldehydes does not proceed to completion under the conditions used. The corresponding equilibrium constants were determined and employed to calculate the rate of the reaction at completion. For all the reactions studied, the pH-rate profiles, extrapolated to zero buffer concentration, show one break at pH 4-5, characteristic of a change in the rate-determining step from ...
