Simultaneous deconstructive ring-opening and skeletal reconstruction of an inert, aromatic pyridinium ring is of great importance in synthetic communities. However, research in this area is still in its infancy. Here,...

Wide line nuclear magnetic resonance studies of pyridinium hexafluorophosphate, chloride, and nitrate show line width and second moment transitions which are attributed to reorientational motions of the pyridinium ring. The differences in transition temperatures are due to the different hydrogen bonded structures in the three salts.
