(Z)-4-(2-Naphthyl-amino)-pent-3-en-2-one
Abstract:
The title compound, C(15)H(15)NO, which was synthesized under solvent-free conditions by the reaction of acetoacetone and 2-naphthyl-amine, adopts a Z conformation about the C=C bond. The enamine-ketone fragment is approximately planar [maximum deviation = 0.026 (3) Å] and forms a dihedral angle of 39.78 (3)° with the naphthalene ring system. An intra-molecular N-H⋯O hydrogen bond is observed.

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
