Principal Component Analysis (PCA) was carried out on the basis of property descriptors for a set of α-halogenated ketones and aldehydes. The obtained PCA model showed that the chemical behaviour of the compounds with 1-ethoxy-3-trimethylsilylprop-1-yne is related to the steric effect of the structural environment of the C=O group. Moreover the PCA model, the steric effect was underlined quantitatively
基于一组α-卤代酮和醛的性质描述符进行了主成分分析(PCA)。所得PCA模型表明,具有1-乙氧基-3-三甲基甲
硅烷基丙-1-炔的化合物的
化学行为与C = O基团的结构环境的空间效应有关。此外,PCA模型的空间效应用回归分析模型定量强调。
