2-Naphthaldehyde Chemical Properties,Usage,Production

Chemical Properties

Pink crystalline

Uses

2-Naphthaldehyde aids in stereo-selective formation of bicyclo 2-siloxy-2-alkoxyoxetanes. It is also used as catalytic agent and petrochemical additive.

Uses

2-Naphthaldehyde can be used as a reactant:

  • In proline catalyzed aldol reaction.
  • In asymmetric three-component Mannich reaction.
  • For the synthesis of Hantzsch 1,4-dihydropyridines.13}
  • Asymmetric benzoin condensation reaction.
  • For the synthesis of pyrazolo[1,2?b]phthalazinediones.
  • For the synthesis C60 by flash vacuum pyrolysis.

Definition

ChEBI: A naphthaldehyde that is naphthalene substituted by a formyl group at position 2.

Synthesis Reference(s)

Synthesis, p. 470, 1996 DOI: 10.1055/s-1996-4246

Purification Methods

Distil 2-naphthaldehyde with steam then crystallise it from water or EtOH. [Beilstein 7 IV 1288.]
