Abstrakt: 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.
