Nuclear energy phenols

The nuclear magnetic resonance spectra of SchifF bases formed from primary amines and ortAo-hydroxy aldehydes and ketones show that the Schiff bases derived from l-hydroxy-2-acetonaphthone and from 2-hydroxy-1-naphthaldehyde exist as keto amines (7a) although their formation involves loss of most of the resonance energy of one of the aromatic rings When R is a phenyl group, the phenol-imine tautomer (7b) predominates Schiff bases derived from ortho-hydroxy aldehydes and ketones have the phenol-imine structure (8) . Evidently, in such compounds the keto-amine tautomer... [Pg.596]
