Synthesis, characterization and coordination behavior of novel Schiff base ligands derived from pyridine anologues

SYNTHESIS, CHARACTERIZATION AND COORDINATION BEHAVIOUR OFNOVEL SCHIFF BASE LIGANDS DERIVED FROM PYRIDINE ANALOGUESAyşegül BULDAĞSUMMARYSchiff bases and their metal complexes have been widely studied due to theirstraightforward prepration and their selectivity and affinition towards metal atoms.Schiff base ligands can be easily synthesised from the condensation of primer amineswith active carbonyl compounds. They form highly stable complexes with metal atoms.Amine and carbonyl compounds that contain second functional group are able to form 5-6membered chelate rings by condensation. Recently, chelate complexes have been attractedconsiderable interest in biology due to their antitumor, antibacterial and antifungal properties.Transition metal complexes of salicylaldehyde-amine derivatives are found to be a potentialcatalyst in organic chemistry for addition of oxygen to organic substrates.This work aims to prepare novel Schiff bases from amines namely 3,3'-diamino-2,2'-bipyridine and 2-amino-3-hydroxy pyridine with aldehydes such as salicylaldehyde andphthalaldehyde.First row transition metal ( Co(II), Ni(II), Cu(II) ve Zn(II) ) complexes of these ligandsare also be prepared characterised and their coordination behaviour investigated.Key words: Schiff bases, Pyridine, Metal complex.
