Carboxylic Acids and their Derivatives

Amic acids Rule C-431

431.1 - When a dicarboxylic acid has a trivial name and when one of its carboxyl groups is replaced by a carboxamide group -C(=O)-NH2, the resulting amic acid is named by replacing the suffix "-ic'' of the trivial name of the dicarboxylic acid by the suffix "-amic".

Examples to Rule C-431.1

The following names are also recommended:

431.2 - Acyl radicals derived from the above amic acids are named by replacing the "-amic acid" ending by "-amoyl''.

Examples to Rule C-431.2

431.3 - When the corresponding dicarboxylic acid has a trivial or semitrivial name, N-phenyl derivatives of-amic acids are named by changing the ending "-amic acid'' to "-anilic acid''.

Examples to Rule C-431.3

431.4 - Ionoamides of dicarboxylic acids without trivial names and the mono- or di-amides of tricarboxylic acids, etc., are designated as carbamoyl derivatives of the acid named on the basis of the remaining carboxyl groups.

(This Rule is partly alternative to Rule C-431.1.)
