Kinetics of reactions between 2-phenylethyl benzenesulphonates and anilines in methanol at 65.0 °C have been studied; the mechanism is discussed on the basis of cross interaction constants, ρij. The overall reaction was found to proceed by a dissociative SN2 mechanism with a relatively small degree of aryl participation. The fraction of the phenonium ion intermediate captured by the nucleophile, aniline
研究了在65.0°C下2-苯乙基苯磺酸盐与苯胺在甲醇中的反应动力学。该机构被交叉相互作用常数,ρ的基础上讨论IJ。发现整个反应是通过离解的S N 2机理进行的,其中芳基的参与程度相对较小。亲核辅助途径中,亲核试剂苯胺所捕获的苯离子中间体的分数已显示出随着亲核试剂的增强而增加,并且对于芳基-建议在分子间S N i机理中出现四中心过渡态。无辅助路径。
