Abstract

The correlations of the H NMR, C NMR and FT-IR spectral data from the R-O-C[double bond, length as m-dash]O groups in the alkyl carbamates and esters of homologous alcohols reveal R-group-dependent negative charge stabilization at the carbonyl oxygen and their donation to generic acceptors at C of even alkyl alcohols (R), which explains several of their apparently anomalous properties.

摘要

来自同系醇的烷基氨基甲酸酯和酯中R-O-C=O基团的氢核磁共振（¹H NMR）、碳核磁共振（¹³C NMR）和傅里叶变换红外光谱（FT-IR）数据的相关性表明，在羰基氧处存在依赖于R基团的负电荷稳定作用，并且这些负电荷会向偶数碳醇（R）的C原子处的一般受体供体，这解释了它们一些明显异常的性质。
