国际有机化学命名法研究(二)现代取代命名法 Studies on the International Nomenclature of Organic Chemistry: (II) Modern Substitutive Nomenclature

从历史发展和化学原理对IUPAC取代命名进行了研究，发现其中不合理的论述和命名过程是由于错误地将特性基团看作官能团，并且代替了官能团。正确地将特性基团作为形成官能团的取代基，同时将这两种基团合理地用于取代命名，结果形成以取代后缀为标志的现代取代命名。它较无特性基团参与的取代命名更为系统化，更便于对不同结构化合物的命名，并且与CA取代命名一致。 IUPAC substitutive nomenclature is studied from its historical development and chemical theory. It is found that mistaking and using characteristic group as functional group result in forming ir-rational naming rules and procedures. By taking characteristic group as a substituent producing functional group after substitution and correctly using these two groups in the nomenclature, modern substitutive nomenclature, characterized by the substitutive suffix, is formed. Modern substitutive nomenclature is more systematic and more versatile in naming organic compounds of various structures than the previous substitutive nomenclature without characteristic group in-volved. It is also in agreement with the “naming selection principle” of CA.
