2-Quinolinecarboxaldehyde Usage And Synthesis | |
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. |
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.] |
