Behavior of carboxylic acids and carboxylic anhydrides in sulfuric acid

Canadian Journal of Chemistry, 1967
The behavior of some carboxylic acids and anhydrides in sulfuric acid has been investigated by cryoscopic and conductimetric measurements in 100% H2SO4, cryoscopic measurements in aqueous H2SO4, and conductimetric titrations in dilute oleum.The previously established behavior of acetic anhydride in dehydrating sulfuric acid, [Formula: see text]is ...

CARBOXYLIC ACIDS

1983
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, 2001
A 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.

Cerium(IV) Carboxylate Photocatalyst for Catalytic Radical Formation from Carboxylic Acids: Decarboxylative Oxygenation of Aliphatic Carboxylic Acids and Lactonization of Aromatic Carboxylic Acids

Journal of the American Chemical Society, 2020
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 ...

Carboxylic acids - snapshot

2022
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.

Phenanthrene-4-carboxylic Acid and 1,2-Dihydrophenanthrene-4-carboxylic Acid

Acta Crystallographica Section C Crystal Structure Communications, 1998
Phenanthrene-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.
