OH– an approximately linear Hammett correlation is found. Common chloride ion effects on the hydrolysis rate constants appear to be absent. Nucleophilicsubstitution reactions of substituted thiophen-2-sulphonyl chlorides were also studied in MeOH–MeCN, where the Hammettequation is obeyed. The data appear consistent with an SN2-type mechanism which can shift toward an SN1 or an SAN process depending
Nucleophilic substitution at sulphonyl sulphur. Part 4. Hydrolysis of substituted thiophenesulphonyl halides in water–acetone mixtures

Hydrolysis of substituted thiophene-2-sulphonyl bromides and chlorides have been studied in water and in water–acetonemixtures at 25°C. Curved Hammett plots with an upward concavity are obtained in water and in water-acetone with up to 40% acetone. For solvents richer in acetone (>80%) the Hammett plots become straight lines with positive slopes for both chlorides and bromides. The result are rationalized
在25°C的水中和水-丙酮混合物中,已研究了取代的噻吩-2-磺酰溴和氯化物的水解。在水中以及在含最多40%丙酮的水丙酮中获得具有向上凹度的弯曲Hammett图。对于富含丙酮(> 80%)的溶剂,哈米特图变为氯化物和溴化物均具有正斜率的直线。根据亲核试剂-硫键的形成和硫,卤素键在取代基,核试剂和溶剂的改变上的断裂之间的不同时机,对结果进行了合理化处理。More O'Ferrall势能面模型的应用与S N 2型机制一致,该机制可以向S N 1或S A转移N个过程取决于不同的因素。另一方面,Pross最近提出的VBCM模型进行的预测与实验结果相矛盾。苯甲酰氯和噻吩-2-磺酰氯的某些溶剂分解反应之间的比较表明,这两个亲电子中心之间存在相似的相似性。
