Carboxylate salts nomenclature

The lithium salt of A/-ethy)ethanamine (diethylamine) is called lithium diethylamide,4 but this nomenclature can lead to confusion With compounds of the type RC02NH2, which are derived from carboxylic acids and also are... 

Nomenclature of Carboxylic Acid Salts Salts of carboxylic acids are named simply by naming the cation, then naming the carboxylate ion by replacing the -ic acid part of the acid name with -ate. The preceding example shows that sodium hydroxide reacts with acetic acid to form sodium acetate. The following examples show the formation and nomenclature of some other salts ... 

The nomenclature of esters is similar to the nomenclature of the carboxylic acid salts. The alkyl group bonded to the oxygen atom is named first, then the -ic acid ending of the corresponding carboxylic acid is changed to -oate.

Monadic (or AB) polyamides are based upon a single repeating lactam with, on the one end an amine reactive group, and on the other end a carboxylic acid group. The lactam thus reacts with itself and the number describes the lactam involved. Dyadic (or AABB) polyamides are based on the reaction of a diamine and a diacid. The diamine and the diacid react alternatively with each other in a salt solution. In regards to the nomenclature, the first number describes... 

In the analogy with inorganic acids, the carboxylic acids can be neutralized by bases. The names of the salts which are formed after neutralization follow the inorganic nomenclature. 

Interestingly, the salts of carboxylic acids, utilize the same nomenclature system. Thus, conversion of ethanoic acid (acetic acid, CH3CO2H) to its sodium salt (with, e.g., aqueous sodium hydroxide, NaOH) produces water and sodium ethanoate (sodium acetate, CHsCOi Na" ). Furthermore, when the (RCO2-) group must be named as a substituent, it is called the acyloxy or R-carbonyloxy group. 

Scheme 1 Low-energy structures for the complex of and Trp. Structures can be classified as salt-bridge (SB interaction between the positive metal ion and the negative carboxylate of the zwitterionic amino acid) or charge solvation (CS interaction of the metal ion with Lewis-basic sites of the canonical amino acid). Nomenclature of the various structures further includes the main binding sites of the amino acid...
