The present approach for determining the electrophilicity (E) and nucleophilicity (N) of aldehydes includes a kinetic study of KMNO4 oxidation and NaBH4 reduction of aldehydes. A transition state analysis of the KMNO4 promoted aldehyde oxidation reaction has been performed, which shows a very good correlation with experimental results. The validity of the experimental method has been tested using the experimental activation parameters of the two reactions. The utility of the present approach is further demonstrated by the theoretical versus experimental relationship, which provides easy access to E and N values for various aldehydes and offers an at-a-glance assessment of the chemical reactivity of aldehydes in various reactions.
目前用于确定醛类电亲和性(E)和核亲和性(N)的方法包括对KMNO4氧化和NaBH4还原醛类的动力学研究。对KMNO4促进的醛氧化反应的过渡态分析表明,其与实验结果具有非常好的相关性。通过两种反应的实验活化参数验证了实验方法的有效性。通过理论与实验关系的进一步证明,该方法为各种醛类提供了便捷获取E和N值的途径,并能直观评估醛类在不同反应中的化学反应性。
