Chemical Properties
white to light yellow crystal powder
Uses
2-Quinolinecarboxaldehyde was used in the preparation of:
· 3-(2-quinolyl)-1-phenyl-2-propenone via rapid, tandem aldol-Michael reactions with the lithium, sodium and potassium enolates of acetophenone;
· imine-type ligands;
· sugar-quinoline fluorescent sensor for the detection of Hg2+ in natural water.
Uses
2-Quinolinecarboxaldehyde was used to synthesize 3-(2-quinolyl)-1-phenyl-2-propenone and imine-type ligands.
Purification Methods
Distil it in steam and recrystallise it from H2O. Protect it from light. The semicarbazone has m 254o (from aqueous EtOH), and the picrate has m 197-199o. [Beilstein 21 H 322, 21 III/IV 4034, 21/8 V 442.]
