1,3-dimethyluracil, N-methyl-2-pyridone, and N-methyl-4-pyridone were determined through their reactions with bases derived from carbon acids with known pKa and the reactions of their corresponding carbanions with the carbon acids. No correlation between the stability of the carbanions and the rate of decarboxylation of corresponding carboxylic acids was found.
1,3-二甲基尿嘧啶,N-甲基-2-吡啶酮和N-甲基-4-吡啶酮的6-CH基团的pKa值是通过它们与衍生自具有已知pKa的碳酸的碱的反应及其反应确定的与碳对应的碳负离子。在碳负离子的稳定性与相应羧酸的脱羧速率之间未发现相关性。
