Description
Summary:A series of lithium, sodium, potassium, and ammonium salts were investigated by proton magnetic resonance spectroscopy in 1,3-dimethylethyleneurea, a relatively new non-aqueous solvent of high polarity and moderately high dielectric constant. The salts were found to shift the solvent proton peaks linearly as a function of salt concentration. Thiosulfate, perchlorate, and iodide salts shifted the solvent peaks downfield while tetraphenylborate salts uniquely shifted the peaks upfield indicating an unusual type of solvation behavior for the tetraphenylborates in this solvent.
