对不同α-卤缩醛低能构象的结构分析揭示了键长和几何形状的变化,这些变化对应于稳定的轨道相互作用,从而形成了这些体系的基态结构。几个因素,包括环上取代基的给电子和接受电子的能力,影响这些类碳水化合物体系中电子相互作用的程度。可以参与超共轭的α-卤素原子的存在有助于低能构象的结构特征。实验证据由自然键序(NBO)分析支持,以确定相互作用的类型并评估其相对重要性。
The analysis of the structures of low-energy conformers of different α-haloacetals reveals changes in bond lengths and geometries that correspond to stabilizing orbital interactions that contribute to the ground-state structures of these systems. Several factors, including the electron-donating and electron-accepting abilities of the substituents on the ring, affect the degree of the electronic interactions in these carbohydrate-like systems. The presence of an α-halogen atom that can participate in hyperconjugation has been shown to contribute to the structural characteristics of the low-energy conformer. The experimental evidence is supported by natural bond order (NBO) analysis to identify the types of interactions and to assess their relative importance.
