Deoxygenative Functionalizations of Aldehydes, Ketones and Carboxylic Acids.
Angewandte Chemie, 2021Conversion of carbonyl compounds, including aldehydes, ketones and carboxylic acids, into functionalized alkanes via deoxygenation would be highly desirable from a sustainability perspective and very enabling in chemical synthesis. This review covers the

This chapter discusses carboxylic acids that generally have high mobilities compared with those of proteins. Carboxylic acids used as model substances for checking both theoretical aspects and correct functioning of the equipment are separated qualitatively and quantitatively by isotachophoresis.

Degradation of Deep-Eutectic Solvents Based on Choline Chloride and Carboxylic Acids
ACS Sustainable Chemistry and Engineering, 2019Mixtures of carboxylic acids and choline chloride are one of the most commonly used families of deep-eutectic solvents. The thermal and long-term stability of carboxylic acid–choline chloride (ChCl) deep-eutectic solvents was investigated. This family of

In fluorene-1-carboxylic acid, C14H10O2, the sole hydrogen bond is of the cyclic dimer type about a center of symmetry. The carboxyl H atom is ordered. Distances in the fluorene core are very similar to those in fluorene itself; the fluorene core dihedral angle is, however, larger than in fluorene.

The title acid, C10H7NO2, crystallized in the centrosymmetric space group P2(1)/c with one molecule in the asymmetric unit. There is a single hydrogen bond. O-H...N, with a donor-acceptor distance of 2.596 (1) A. The carboxylic H atom is ordered. The dihedral angle between the best-fit quinoline core plane and the carboxyl plane is 45.9 (1) degrees ...
