8-Quinolinecarboxylic acid Usage And Synthesis

Chemical Properties

white to light yellow crystal powder

Uses

8-Quinolinecarboxylic acid may be used in the synthesis of novel oxorhenium(V) complexes incorporating quinoline and isoquinoline carboxylic acid derivatives, chiral 1,2,3,4-tetrahydroquinolinyl-oxazoline compounds, used as ligands for Ru-catalyzed asymmetric transfer hydrogenation of ketones and chiral quinolinyl-oxazoline compounds, used as ligands for Cu(II) catalyzed asymmetric cyclopropanation.

Uses

8-Quinolinecarboxylic acid may be used in the synthesis of:

• novel oxorhenium(V) complexes incorporating quinoline and isoquinoline carboxylic acid derivatives
• chiral 1,2,3,4-tetrahydroquinolinyl-oxazoline compounds, used as ligands for Ru-catalyzed asymmetric transfer hydrogenation of ketones
• chiral quinolinyl-oxazoline compounds, used as ligands for Cu(II) catalyzed asymmetric cyclopropanation

General Description

Herbicide 8-quinolinecarboxylic acid and its removal from aqueous solution using sodium montmorillonite, acidic montmorillonite and organo-acidic montmorillonite has been reported.

Purification Methods

Crystallise the acid from water, aqueous EtOH, EtOH or *C6H6. The ethyl ester has m 45o and b 194-197o/13mm. [Beilstein 22 H 81, 22 III/IV 1200, 22/3 V 217.]
