A Simple Alternative Method for the Synthesis of Aromatic Dialdehydes

Abstract

Aromatic dialdehydes were synthesized from 5-t-butylsalicylaldehyde and o-vanilline in good yields using paraformaldehyde, hydrobromic acid and catalytic amounts of sulfuric acid in one step which was previously unavailable with present methods.

Keywords

• aromatic dialdehydes
• bromomethylation
• 5-t-butylsalicylaldehyde
• o-vanilline.
