Beschreibung

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.
