The cycloadditions of nitrile oxides with new and previously studied allylic fluorides were examined. The 1,3-dipolar cycloaddition reactions were also investigated theoretically with density functional theory (B3LYP) based transition-state modelling. The predictions provided reasonable agreement with experiment, indicating that both steric and electronic effects have important influences on the stereoselectivities
研究了新的和先前研究过的烯丙基氟化物对腈氧化物的环加成反应。还使用基于密度泛函理论(B3LYP)的过渡态建模理论研究了1,3-偶极环加成反应。这些预测与实验提供了合理的一致性,表明空间效应和电子效应均对这些反应的立体选择性具有重要影响。
