Abstract
The solution behavior of a series of alkali metal tetraphenylborates, perchlorates, and iodides in 1,1,3,3-tetramethylurea (TMU) has been studied by proton nuclear magnetic resonance (NMR) spectroscopy. TMU has a simple proton NMR spectrum consisting of one singlet at 2.75 ppm. Alkali metal tetraphenylborates and perchlorates were observed to be dissociated in TMU. Sodium iodide, however, was observed to be associated in TMU. Present results are compared with those from other NMR investigations in TMU and related nonaqueous solvents. Keywords: alkali metal salt solvation, tetramethylurea, nuclear magnetic resonance, solute–solvent interactions.
