摘要

研究了14种不对称取代的1,3-二氧杂环的核磁共振光谱,并对它们的温度依赖性提供了取代基构象要求的信息。其中6个分子的环转化过程热力学参数可以得到评价。

Nuclear magnetic resonance studies of some asymmetrically substituted 1,3-dioxans
The n.m.r. spectra of 14 asymmetrically substituted 1,3-dioxans have been examined and their temperature-dependence has provided information on the conformational requirements of the substituents. Thermodynamic parameters for the ring inversion process could be evaluated for six of these molecules.
