Acid halide nomenclature

We study the nomenclature, structure, and characteristic reactions of acid halides in Chapter 14. In this chapter, our concern is only with their synthesis from carboxylic acids. 

Nomenclature for carboxylic acids and dicarboxylic acids. Structure and nomenclature for acid halides, anhydrides, esters, and amides.

The nomenclature of the imidoyl halides is not clearly established I have therefore attempted to select names which identify the compounds as imidoyl halides, and which furthermore, relate to their chemistry. For example. Chemical Abstracts lists the hydroxamoyl chlorides as oximes of the corresponding carboxylic acid chlorides. Although this name is formally correct, it does not reflect the chemistry of this class of compounds, which is closely related to hydroxamic acids, its hydrolysis products. 

The nomenclature of this class of compounds is not at all clear. For example, the following names can be found in the literature hydroxamic acid chlorides, hydroxamic chlorides, hydroximic chlorides (Beilstein lists them as Hydroximsaure chloride ), and acyl and aroylchloride oximes. The latter names are used by Chemical Abstracts, Although the name benzoyl chloride oxime for benzhydroxamoyl chloride is formally correct, it does not reflect the close relationship between hydroxamoyl chlorides and hydroxamic acids, their hydrolysis products. In order to be consistent with the nomenclature used in the earlier chapters, I prefer the term hydroxamoyl to hydroxamic chloride. The interrelationship of the halides with the corresponding acids is shown below, and R is representative of the alkyl, aryl, acyl, aroyl, and carbalkoxy group.
