Formation of New Tetradentate Schiff Base Metal Chelates

Abstract

Condensation products of o-aminophenol, N-substituted-o-aminophenols, and 8-amino-1-naphthol with α-diketones have been compared. The basis for the lack of reactivity of these products to yield Schiff base chelates for the cases where the parent diketone is different from glyoxal was examined. Steric factors alone did not appear to influence the reaction.
