? Because they have been known for so long, the common acids, esters, and other acyl compounds are often referred to by their common names. 11.2 Nomenclature of Carboxylic Acid Derivatives ? Some common acids are formic acid (HCO2H), acetic acid(CH3CO2H), and benzoic acid (C6H5CO2H)...

The reaction could be efficiently accelerated by IrI4 catalyst and LiI promoter in AcOH solvent at 170 °C, and the yield of C5 carboxylic acids reached 70% after 16 h (entry 1). The products contained two isomers, i.e., pentanoic acid and 2-methylbutanoic acid, and their molar ...
Many carboxylic acids (acetic acid, citric acid, lactic acid) are intermediates in metabolism and can be found in natural products; others (e.g., salicylic acid) are used as solvents and to prepare many chemical compounds. Important carboxylic-acid derivatives include esters, anhydrides, amides,...
