1H NMR chemical shifts for some α-hetero-substituted N,N-diethylacetamides were recorded. The resonance assignments for the syn- and anti-methylene and -methyl protons have been made unambiguously through their aromatic solvent induced shifts and are opposed to the literture assignments for the N...
DMSO the water is already stronglyhydrogen-bonded to the solvent, and solutes have only anegligible effect on its chemical shift. This is also truefor D2O; the chemical shift of the residual HDO is verytemperature-dependent (vide infra) but, maybe counter-intuitively, remarkably solute (and pH...
