Specific Classes of Compounds

R-5.7.6 Acid halides

Acid halides in which hydroxy groups of all acid groups expressed as the principal characteristic group (carboxylic, sulfonic, sulfinic, selenonic, etc., acids) have been replaced by halogen atoms are named by citing the name of the acyl group (see R-5.7.1.1) followed by the name(s) of the specific halide(s) as separate words, in alphabetical order, each preceded by a multiplicative prefix, as needed.

Examples to R-5.7.6

When another group is present that has priority for citation as prinsipal group or when attached to a substituting group, an acyl halide group is expressed by a prefix such as "fluorocarbonyl-", "chlorocarbonyl-", "bromocarbonyl-" or "iodocarbonyl-".

Examples to R-5.7.6

Mononulcear oxo acid halides and analogues named by functional replacement nomenclature (see R-3.4), which may be named as acyl halides as described above, are often named by replacing the term "acid" of the acid name by the appropriate halide class name(s).
