Notes:
---Cation-anion interactions in 2-propanol solutions of sodium salts NaY (Y = MeS, iPrS, tBuS, iPrO, SCN, ClO4, Ph4B) have been studied by 23Na-NMR spectroscopy. The analysis involved measurements of chemical shift and T1 as a function of salt concentration in both the absence and presence of the Na+-complexing agent 18-crown-6. The results indicate that the interactions of Na+ with alkoxides and thiol anions are very different from those with charge-delocalized anions (SCN-, ClO4-, Ph4B-), and that the degree of association in NaSR salts is greater for R = tBu than for R = Me.
