It is to be noted that formic acid has a high potential for CO2 emission reduction (Sternberg et al., 2017). The reaction of CO2 with organic substances produces a variety of chemicals, such as carboxylic acids, carbonates, and carbamates (Zhang & Hou, 2017). Carboxylic acids are ...

ATR-IR spectra again provided molecular-level insights into the relevant interactions. As expected, the ionic interaction between the acid group of the selectand and the amine group of the selector is the strongest. The main force responsible for enantiodifferentiation is, however, the specific ...
Following coordination of the carbonyl oxygen to the tin, addition of hydrogen peroxide to give a “Criegee intermediate” is assumed which can undergo aryl migration (shown) towards the formate ester or H-migration to the carboxylic acid. The strongly electron-donating 4- and 2-alkoxy ...
Carboxylic acid can be targeted by carbodiimide and dihydrazides. The most widely used carbomiimide is 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC), which is often referred to as “zero-length” cross-linker as it facilitates a covalent linkage between carboxylate groups and primary amines...
