Diethyl 2-{[2-(trifluoromethyl)anilino]methylidene}propanedioate

Abstract

The title compound, C15H16F3NO4, is an N-substituted derivative of ortho-trifluoromethylaniline featuring a twofold Michael system. The least-squares planes defined by the atoms of the phenyl ring and the atoms of the Michael system enclose an angle of 15.52 (5)°. Apart from classical intramolecular N—H...O and N—H...F hydrogen bonds, intermolecular C—H...O contacts are observed, the latter connecting the molecules into chains along [110]. The shortest intercentroid distance between two aromatic systems is 3.6875 (9) Å
