Publisher Summary Laboratory methods for the synthesis of carboxylic acids are oxidation, oxidation-reduction reactions, carbonation of organometallics, condensation reactions, and hydrolysis reactions. This chapter discusses the haloform reaction that is used for the oxidation of aliphatic methyl ketones or of methyl carbinols to carboxylic acids ...

Acidity of Carboxylic Acids: A Rebuttal and Redefinition
Journal of the American Chemical Society, 2001A recent theory of ionization of carboxylic acids divided the process of ionization into two steps and attributed the main importance to the electrostatic potential of the acid molecule. The origin of the acidity was thus seen in the high energy of the acid molecule and not in the stabilization of the anion by resonance.

We found that in situ generated cerium(IV) carboxylate generated by mixing the precursor Ce(OtBu)4 with the corresponding carboxylic acids served as efficient photocatalysts for the direct formation of carboxyl radicals from carboxylic acids under blue light-emitting diodes (blue LEDs) irradiation and air, resulting in catalytic decarboxylative ...

A carboxylic acid is an organic acid that contains a carboxyl group (C(=O)OH) attached to an R-group. The general formula of a carboxylic acid is R−COOH or R−CO2H, with R referring to the alkyl, alkenyl, aryl, or other group. Carboxylic acids occur widely. Important examples include the amino acids and fatty acids.

Catalytic Conversion of Alcohols to Carboxylic Acid Salts and Hydrogen with Alkaline Water
, 2017A [RuH(CO)(py-NP)(PPh3)2]Cl (1) catalyst is found to be effective for catalytic transformation of primary alcohols, including amino alcohols, to the corresponding carboxylic acid salts and two molecules of hydrogen with alkaline water.

Reductive electron transfer (ET) to organic compounds is a powerful method for the activation of substrates via the formation of radicals, radical anions, anions, and dianions that can be exploited in bond-cleaving and bond-forming processes.

Phenanthrene-4-carboxylic Acid and 1,2-Dihydrophenanthrene-4-carboxylic Acid
Acta Crystallographica Section C Crystal Structure Communications, 1998Phenanthrene-4-carboxylic acid, C15H10O2, crystallized in the centrosymmetric space group P2(1)/n, while 1,2-dihydrophenanthrene-4-carboxylic acid, C15H12O2, crystallized in the centrosymmetric space group Pbca. In each structure, there is a single type of hydrogen bond: it is of the cyclic dimer type about a center of symmetry.

Green Carboxylic Acid-Based Deep Eutectic Solvents as Solvents for Extractive Desulfurization
, 2016The extractive desulfurization of thiophene (TS), dibenzothiophene (DBT), and benzothiophene (BT) in model oil was carried out using carboxylic acid-based deep eutectic solvents (DES).
