The acylations of l-menthol with p-substituted benzoyl- and substituted acetyl chlorides were carried out, and it was found that the electron-releasing substituents accelerate the reaction rate in chloroform even though the reaction is completely of the SN2 type. This result is interpreted in relation to the low isokinetic temperature, the reaction itself being carried out above that temperature. Such a phenomenon is discussed in terms of the configurational and the solvent effects on the entropy of activation.
研究人员用对取代的苯甲酰氯和取代的乙酰氯对 l-薄荷醇进行了酰化反应,结果发现,尽管反应完全是 SN2 类型的,但在氯仿中释放电子的取代基会加快反应速率。对这一结果的解释与低等动力学温度有关,反应本身是在该温度以上进行的。我们从构型和溶剂对活化熵的影响角度讨论了这一现象。
