Conformational Equilibria of N,N-Dimethylsuccinamic Acid and Its Lithium Salt as a Function of Solvent

Abstract
The conformational preferences of N,N-dimethylsuccinamic acid and its Li^+ salt were estimated by comparing the respective experimental NMR vicinal proton–proton coupling constants to semiempirical coupling constants for each staggered conformer as derived by the Haasnoot–De Leeuw–Altona method. The strong gauche preferences for the Li^+ salts clearly depended more on the solvents' hydrogen-bond donating strength (α) than on their hydrogen-bond accepting (β) counterpart, where α and β are the corresponding Kamlet–Taft parameters.
