用FT-IR、Laser Raman光谱和EHMO计算研究了β-羟基酯脱水反应,发现反应产物α、β-烯酯和β、γ-烯酯两类共轭与非共轭构异体的分布,主要取决于β-碳上的取代甲基超共轭效应,该反应是受动力学控制的。
The dehydration reaction of β-hydroxyester was studied by FT-IR, Laser Raman spectroscopy and EHMO. The distributions of the conjugated and unconjugated conjugated α, β-enoester and β-γ-ene ester were found mainly Depending on the substituted methyl hyperconjugation effect on the β-carbon, the reaction is kinematically controlled.
