Bent structure and dynamic stereochemistry of chiral acridinium cations.
Chiral acridinium cations, easily prepared by reaction of enantiopure primary amines and tris(2,6-dimethoxy)trityl cation, display restricted rotations around the C(sp(3))-N(sp(2)) bond. A bending of the aromatic backbone and "out-of-plane" displacements of C(9) and N(10) atoms are enforced if bulky amines are introduced.
