| | Definition | ChEBI: 3-Cyanochromone is a member of chromones. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 64, p. 8736, 1999 DOI: 10.1021/jo991031j | | General Description | 3-Cyanochromone (4-Oxo-4H-1-benzopyran-3-carbonitrile), a 3-substituted chromone, is a cyano substituted 1-benzopyran-4-one. It is an α,β-unsaturated nitrile and also an α,β-unsaturated ketone. Its molecule has electron deficiency at 3 sites i.e C (carbon) at second position, C of cyano and carbonyl group. 2-Amino-3-(alkyliminomethyl)chromones are obtained as major products during its reaction with aliphatic amines. |
