Today, I performed an NMR Spectroscopy on an unknown solution containing an arene and a carboxylic acid. I am having a difficult time figuring out the chemical structure based on the NMR spectra. Below is the data: Chemical Formula: C9H10O4 Proton NMR: 7.0 ppm - multiplet - four hydrogens...

The proton nuclear magnetic resonance spin鈥搇attice relaxation time has been successfully used to evidence the reorientation of the imidazolium rings in carboxylic acid salts of imidazole: imidazolium oxalate, imidazolium adipate monohydrate and diimidazolium suberate. The process occurs in the temperature...
On the background of these findings, we describe in the present article, the formation of new hydrogen bonded proton transfer salt between 2, 6-diaminopyridine and 2-nitrobenzoic acid. The title salt was characterised by various physicochemical methods and screened to evaluate its biological ...
4a, e). This suggests that the complex 1a consisting of carboxylic acid substrate 1n and 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 the 11B NMR signal of B2pin2...
with 6-formyl-4 chromanones, followed by cyclization of the azides obtained leads to 7,8-dihydropyranoindol-9 (1H)-one.One aspect of the chemical reactivity of these new tricyclic systems is described.The structure of the compounds isolated from various syntheses is established by proton nmr ...
