Radical Carboxylative Cyclizations and Carboxylations with CO2
Accounts of Chemical Research, 2021Carbon dioxide (CO2) is not only a greenhouse gas and a common waste product but also an inexpensive, readily available, and renewable carbon resource. It is an important one-carbon (C1) building block in organic synthesis for the construction of valuable compounds.

Carboxyl–carboxylate interactions in proteins
Nature, 1982Much of our present understanding of macromolecular architecture has come from the extrapolation to large molecules of rules derived from analysis of small molecules. This is exemplified by the work of Pauling et al.1 on polypeptide conformation, which depended on the insight afforded by the crystal structures of individual amino acids and some ...

Chem. Soc. Rev., 2010
Dwindling petroleum feedstocks and increased CO(2)-concentrations in the atmosphere currently open the concept of using CO(2) as raw material for the synthesis of well-defined organic compounds. In parallel to recent advances in the chemical CO(2)-fixation, enzymatic (biocatalytic) carboxylation is currently being investigated at an increased pace.

Aliphatic Epoxide Carboxylation
Annual Review of Biochemistry, 2003▪ Abstract Aliphatic epoxides (epoxyalkanes) are highly reactive electrophilic molecules that are formed from the monooxygenase-catalyzed epoxidation of aliphatic alkenes. The bacterial metabolism of short-chain epoxyalkanes occurs by a three-step pathway resulting in net carboxylation to β-ketoacids.

Crystallization of Silver Carboxylates from Sodium Carboxylate Mixtures
Langmuir, 2007Silver carboxylates can be made by the reaction of silver nitrate and the corresponding sodium carboxylates. The length of the alkyl chain has a significant impact on the product behavior. In this study, 18, 20, and 22 carbon chains (stearate, arachidate, and behenate, respectively) have been selected.

Free Carboxylate Stretching Modes
The Journal of Physical Chemistry A, 2008We report the first IR spectroscopic observation of carboxylate stretching modes in free space, i.e., in the complete absence of solvent or counterions. Gas-phase spectra of a series of benzoate anions have been recorded and compared to condensed-phase spectra, revealing the profound influence of the environment on the symmetric and antisymmetric ...

Cationic carboxylation of methyl thiophene-2-carboxylate
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1983As exemplified by the electrochemical reduction of methyl thiophene-2-carboxylate, we have shown for the first time the selective one-stage introduction of a carboxyl group into a heteroaromatic ring.
