1- aminocyclo-propane-1-carboxylic acidThe two sets of diastereomeric hydrogen atoms cis and trans to the carboxylate of 1-aminocyclopropane-1-carboxylic acid (ACC) were differentiated by a 1H-nmr study. The measurement of the 1H-nmr spectrum of ACC at pH 3.8 during the successive addition ...
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 ...
4). Firstly, the interactions between the carboxylic acid, arene, and triflic anhydride were monitored by 13C NMR. As shown in Fig. 4a, a significant chemical shift from 181.1 to 189.6 ppm was observed after the addition of Tf2O to the propionic acid 1 solution, indicating the rapid...
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...
NMR (CDCl3),δ, (proton) 3.89 (6H) (methyl protons); 6.86-7.31 (6H) (aromatic protons). 10.0 g of 3,3'-difluoro-4,4'-dimethoxybiphenyl was dissolved in 150 ml of dioxane, and 150 ml of 48% hydrobromic acid was added. The mixture was heated under reflux for 50 hours. After the...
