Rc. Fox et Pd. Taylor, THE SYNTHESIS AND CONFIRMATORY STRUCTURAL CHARACTERIZATION OF TETRADENTATE CHELATORS BASED ON KOJIC ACID, Synthetic communications, 28(9), 1998, pp. 1575-1583
Carbon linked tetradentate chelators based on kojic acid were synthesi
sed by a modification of the Mannich reaction. Suppression of the amin
omethylation process favours the formation of dimeric, Bakerlite-type
structures.
