The acid-catalyzed hydrolysis of arylsulfonyl phthalimides was studied in aqueous solutions of sulfuric, perchloric, and hydrochloric acid at 35.0 ± 0.1°C. Analysis of the data by the excess acidity method and activation parameters, as well as substituent and solvent isotope effects, indicate hydrolysis by an A-2 mechanism at low acidity. At higher acidities, a changeover to an A-1 mechanism is observed
在 35.0 ± 0.1°C 的硫酸、高氯酸和盐酸水溶液中研究了芳基磺酰邻苯二甲酰亚胺的酸催化水解。通过过量酸度方法和活化参数以及取代基和溶剂同位素效应对数据的分析表明,在低酸度下通过 A-2 机制进行水解。在较高的酸度下,观察到转变为 A-1 机制。
