    • 10 Actually, in order to avoid uncontrolled growth of compounds of diverse nuclearity, one of the two chelating sites of a bis-chelating ligand is protected by methylation at a pyridine nitrogen. The obtained intermediate will than be employed in subsequent preparative steps, after deprotection of the previously blocked chelating function.
