β(3-甲基-2,4-二氧代环己基)丙酸及其衍生物的NMR研究

NMR Study of β-(3 -Methyl- 2, 4 -Dioxocyclohexyl) Propionic Acid and Its Derivatives

本文测定了五个β(3-甲基-2,4-二氧代环己基)丙酸及其衍生物的^(13)C和^(1)HNMR谱.观测到了酮-烯醇互变异构现象.讨论了这些化合物的分子结构.酮-烯醇互变异构是人们熟知的慢交换过程,利用NMR方法对其进行研究,不影响酮-烯醇的平衡位置,是研究此类化合物的较为理想的方法^([1]).

^(13)C and ^(1)H NMR spectra of five congeners of β-(3-methyl-2,4-dioxocyc-lohexyl) propionic acid were determined in this work. Ketone-enol tautomerism was observed. The structures of these compounds were discussed.
