4-[(4-Methylphenyl)amino]pent-3-en-2-one

Abstract

The title enaminoketone, C12H15NO, is a derivative of 4-(phenylamino)pent-3-en-2-one with an approximately planar pentenone backbone, the greatest displacement from the plane being 0.042 (1) Å; the asymmetry in C—C distances in the group suggests the presence of unsaturated bonds. The dihedral angle between the benzene ring and the pentenone plane is 29.90 (4)°. In the crystal, an intramolecular N—H...O interaction and an intermolecular C—H...O hydrogen bond are observed.
