Abstract
CH2Cl2 solutions of five 2-mono and 2,6-disubstituted Mannich bases with different p-substituents were studied by FTIR spectroscopy and compared with their mono and diperchlorates. In the mono and disubstituted bases the H is localized at the O in the intramolecular OH⋯N bonds. In the mono salts of the disubstituted compounds an (NH⋯OH⋯N)+⇌(N⋯HO⋯HN)+ hydrogen-bonded system is formed. An IR continuum indicates that this system shows proton polarizability due to collective proton motion. This system is destroyed in the dihydroperchlorates. © 1988.
