Electrochemical Borylation of Carboxylic Acids [PDF]

open access: yesProceedings of the National Academy of Sciences, 2021
Significance Boronic acids are one of the most useful functional groups in organic chemistry and can be used as intermediates in synthesis or as key motifs in medicines. This work describes an extremely simple and economical way to use electrochemistry to convert carboxylic acids, through the intermediacy of redox-active esters, to ...

Characterizing the growth of PHA-producing microorganisms on short-chain carboxylic acids [PDF]

open access: yesMicrobial Cell Factories
Short-chain carboxylic acids are important chemical intermediates in anaerobic treatment or thermal hydrolysis of biowaste. They are a crucial precursor for the production of Polyhydroxyalkanoate (PHA) by various microorganisms. However, there is limited

CARBOXYLIC ACIDS

open access: yes, 1983
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.

A review of anodic catalysts and their application in (non-)Kolbe electrocatalytic decarboxylation of carboxylic acids

open access: yesCarbon Resources Conversion, 2023
Biomass, as the exclusive and abundant organic resources, is considered to be the promising renewable resource. Carboxylic acids are one of the many compounds that can be obtained from raw biomass.

Recent advances in decarboxylative nitration of carboxylic acids [PDF]

open access: yesChemical Review and Letters, 2019
In this review, we will summarize the available literature on the preparation of nitro compounds from the corresponding carboxylic acids through nitrodecarboxylation. The review is divided into three major sub-sections.

Carboxylic acids - snapshot

open access: yes, 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.

Cobalt-Catalyzed Tandem Deamination, Decarboxylation, and Dehomologation of Primary Amines to Carboxylic Acids in Water

open access: yes, 2022
Selective transformation of carboxylic acids through oxidative deamination of primary amines is a catalytically challenging and useful transformation. Herein, we present a simple protocol for the transformation of primary amines to carboxylic acids with ...

Carboxylic acids and light interact to affect nanoceria stability and dissolution in acidic aqueous environments

open access: yesBeilstein Journal of Nanotechnology, 2023
Cerium atoms on the surfaces of nanoceria (i.e., cerium oxide in the form of nanoparticles) can store or release oxygen, cycling between Ce3+ and Ce4+; therefore, they can cause or relieve oxidative stress within living systems.

Effects of Carboxylic Acids on Friction and Wear Reducing Properties for Alkylmethylimidazolium Derived Ionic liquids

open access: yesTribology Online, 2006
Lubricant additive technology to improve lubricant performances is an important issue for ionic liquids to be applied practically. Effects of carboxylic acids with different carbon chain length in ionic liquid on tribological properties were examined ...
