824.1 - The compound is named as an N-substituted amide, the substituents and being cited as prefixes.
Note: This method is particularly suitable when the group in the acyl residue R1CO- is more complex than the group , or and , in the amine residue or .
824.2 - Alternatively, the acyl group is named as an N-substituent of the base.
Examples to Rule C-824.1
Note: This method is particularly suitable when the group in the acyl residue is less complex than the group , or and , in the amine residue or , and for use with derivatives of nitrogen containing heterocyclic compounds.
824.3 - As a further alternative, for mono-N-substituted primary amides the group is treated as a substituent into the compound and is named by changing the ending "-amide" to "amido-" or "-carboxamide" to "carboxamido-".

(but see also Rule C-824.3)
(but see also Rule C-824.4)
(see Rule C-304.3)
(see Rule C-304.1)
824.4 - For di-N-substituted primary amides the procedure of Rule C-824.3 is applied, the less complex of the groups and being named as substituent of the amido or carboxamido group with locant N.
Examples to Rule C-824.3
(but see also Rule C-824.2)
Note: The procedures of Rules C-824.3 and C-824.4 are particularly suitable when the group in the acyl residue is less complex than the group , or and , in the amine residue or ; they are not applicable to derivatives of N-acyl nitrogen-containing heterocyclic systems.
