Carboxylic Acids and their Derivatives

Salts and Esters Rule C-463

463.1 - Neutral esters of carboxylic acids, etc., are named in the same way as their neutral salts except that (a) the name of the alkyl or aryl, etc., radical replaces the name of the cation and (b) a periphrase such as "(alkyl or aryl) ester" replaces "(metal) salt".

Examples to Rule C-463.1

463.2 - Acid esters of carboxylic acids, etc., and their salts, are named analogously to neutral esters, but the components are cited in the order cation, alkyl or aryl, etc., radical, hydrogen, anion. Locants are added if necessary.

Examples to Rule C-463.2

463.3 - Ester groups in compounds are named (a) by use of a prefix "alkoxycarbonyl-" or "aryloxycarbonyl-", etc., for the group when the radical R1 contains a substituent with priority for citation as principal group, or (b) by use of a prefix "acyloxy-" for the group when the radical contains a substituent with priority for citation as principal group.
