Benzoic acid tends to form more stable complexes than acetic acid. The binding force is due to a pair of hydrogen bonds, Ocarboxyl–H…O=Camide and C=Ocarboxyl…H–Namide, between the carboxyl group of a guest molecule and the amide group of a host molecule. The former bond is ...
Calconcarboxylic acid, with the chemical formula C30H20N2O10S2, has the CAS number 3737-95-9. It appears as a yellow powder with no distinct odor. The basic structure of calconcarboxylic acid consists of a complex organic molecule containing carbon, hydrogen, nitrogen, oxygen, and sulfur atom...

thiadiazolylphenoxybutanoic acid30by addition of water [69]. The occurrence of the lyotropic layer structure arises from the ether oxygen inclose proximityto the carboxylic acid group. The ether oxygen acts as an efficient proton acceptor and participates in the formation of ahydrogen bondingnetwork ...
Studies of hydrogen bonding in carboxylic acid-dimethyl sulfoxide systems by nuclear magnetic resonance dilution shifts Nmr dilution shifts have been measured for binary systems of carboxylic acids and dimethyl sulfoxide (DMSO). The acids studied were acetic, propionic, isob... H Fujiwara - 《Journal...
(Fig.4a, e). This suggests that thecomplex 1aconsisting of carboxylic acid substrate1nand TMG is the crucial intermediate for decarboxylation of the carboxylic acid and turnover of the photocatalytic cycle. The presence of TMG resulted in a significant reduction in the11B NMR signal of B2pin2,...
