Web8 mei 2016 · The reaction is likely with one equivalent of acetic anhydride and under thermodynamic control. Kinetically, the nucleophilic attack of phenol on acetic anhydride should be a lot faster than that of aniline. Aniline’s lone pair is taking part in resonance across the phenyl ring so it is barely able to attack. WebFor example, the classic hydrolysis of acetic anhydride is quite slow until temperatures exceed 55—60 °C. Similarly, sulfonyl chloride hydrolysis is very slow until temperatures exceed about 70 °C. This is in part driven by solubility - the substrate needs to be in the same phase as the water for fast rates.
