Abstract :

<p>Schiff base ligands have been extensively studied in co-ordination chemistry, mainly due to their facile synthesis, tunable steric and electronic properties. It is well known that ligands containing &lsquo;N&rsquo; and &lsquo;O&rsquo; atoms can easily co-ordinate metal ions. Therefore Schiff base ligands possessing N,O-donor and chromophore groups are of important building blocks to construct luminescence complexes[1]. The pyrolide anions have received particular research interest, because they offer a reasonable mimic of the cyclopentadienyl functions and could act as competent &eta;5 ligand. Additionally, the pyrolide anions afford the possibility of forming &sigma;-bond through the ring nitrogen donor, providing tunable steric and electronic features required for compensating coordinative unsaturation of metal atoms and enhancing catalytic activity towards polymerization[2]. We have successfully synthesized one of such ligand starting from pyrole-2-aldehyde.</p>
