| Abstract: | Two series of substituted N‐pyrrolyl‐2‐methylene‐aniline were synthesized and characterized to study their stability in a large domain of pH (0–14) and especially in the H0 domain (–4 to 0). The hydrolysis kinetics of the azomethine group was established in homogeneous media using a thermostated UV–vis spectrophotometer. The hydrolysis mechanism was investigated, and the experimental kinetic constants were calculated. Then, the pH–rate diagram profile was determined and the structural effect of substitutes on the kinetic constants was clarified and discussed. |
