assignment of the camphor parent molecule, are reported. The precise substituent‐induced chemical shifts (SCS) obtained for these difunctional systems are examined on the basis of well known transmission mechanisms aided by correlations with steric and electronic parameters, and taking into account SCS data from monohaloalkanes and the calculated molecular geometry data (using the AM1 method).
展示了 3-卤代樟脑(内型和外型)的高场 1H NMR 光谱的完整信号分配,允许改进先前对氯(内型和外型)和溴(内型)衍生物的分析。此外,报告了二氯和外氟衍生物以及三种新化合物(内氟、内碘和外碘)的未发表数据,以及樟脑母体分子的修订分配。在众所周知的传输机制的基础上,通过与空间和电子参数的相关性辅助,并考虑来自单卤烷烃的 SCS 数据和计算的分子几何数据(使用AM1 方法)。
