Study of lone pair-arene interactions in solution
STUDY OF LONE PAIR-ARENE INTERACTIONS IN SOLUTION
By Yan Zou
Lone pair-? interactions in solution have been studied experimentally.
Triptycene-derived model compounds serve as conformational equilibrium reporters
for direct measurements of these interactions. A series of triptycene derivatives with
different 9-substituted benzyl groups were synthesized. VT NMR was applied to
determine the ratio of syn and anti conformers. The free energies differences of the
interactions were also obtained from the syn/anti ratios. The lone pair of oxygen-?
interaction seemed to be attractive with both electron-rich and electron-deficient arene.
This kind of interaction tends to be stronger for the electron-deficient arene. The
electrostatic forces were considered to play a major role. Other kinds of effects, such
as Van Der Waals forces, London dispersion forces also play in part role in the
