4-(Diethylamino)salicylaldehyde

J. Vanco, J. Marek and O. Svajlenová

Abstract: The title compound, C₁₁H₁₅NO₂, contains a planar diethylamine group with an sp²-hybridized N atom bonded to a nearly planar salicylaldehyde fragment. Electron density from the diethylamine group is transferred to a pseudo-ring formed by an intramolecular O-HO hydrogen bond involving the aldehyde and hydroxy groups. In the crystal structure, the molecules form C-HO hydrogen-bonded centrosymmetric dimers.
