Application

Salicylaldehyde can be used to synthesize:
  • Salicylidene-tris(aminomethyl)ethane chelating agent which can form metal chelates with Fe3+, probes for 19F magnetic resonance imaging.
  • Schiff base ligands via condensation with cycloalkylamines.
  • 3-acetylcoumarin, an intermediate for the synthesis of various pyrrolidone fused coumarins and furan fused coumarins.
  • Biologically important 2-amino-4H-chromene scaffolds via multicomponent reaction with nitroalkanes and malononitrile.
