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...
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...
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...
Proton NMR evidence is presented on the number and relative concentrations of complexes formed by W(VI) and L-malic acid (pH range 3–6), their composition, conformation of the ligand moiety, and (briefly) on their pH-dependence and relative rates of formation. In particular, four complexes...
NMR and IR spectroscopy have been used in studying the equilibrium in the reaction of proton transfer from thiocarboxylic acids RCOSH [R=CH3 (a), C6H5 (b) or CH2Cl (c)] to -collidine (d), and also the kinetics of CH/NH proton exchange between protonated -collidine and excess RCOSH...
