In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO (or RCO−2). It is an ion with negative charge. Carboxylate salts are salts that have the general formula M(RCOO)n, where M is a metal and n is 1, 2,.... Carboxylate esters have the general formula RCOOR′ (also written as RCO2R′), where … See more Carboxylate ions can be formed by deprotonation of carboxylic acids. Such acids typically have pKa of less than 5, meaning that they can be deprotonated by many bases, such as sodium hydroxide or sodium bicarbonate See more Nucleophilic substitution Carboxylate ions are good nucleophiles. They react with alkyl halides to form esters. The following reaction shows the reaction mechanism. The nucleophilicity of carboxylate ions are much weaker than … See more • Carboxylic acid See more Carboxylic acids easily dissociate into a carboxylate anion and a positively charged hydrogen ion (proton), much more readily than alcohols do (into an alkoxide ion and a proton), because the carboxylate ion is stabilized by resonance. The negative charge that is left after See more This list is for cases where there is a separate article for the anion or its derivatives. All other organic acids should be found at their parent carboxylic acid. • See more WebJan 2, 2015 · The presence of a trifluoromethyl-substituted oxadiazole moiety in pleconaril, rather than a more hydrophilic group in either pirodavir (ethyl carboxylate group) or BTA-188 (O-ethyloxime group) at structurally equivalent positions (fig.
