Studies of Titanium(IV)complexes of mixed nitrogen and oxygen donor macrocycles and related schiff base ligands

Abstract

This work investigated the use of large tetradentate mixed nitrogen and oxygen donor macrocycles as potential ligands for titanium(IV).These large ligands are capable of encapsulating the metal ion, thereby protecting it from reacting further. In addition, titanium complexes of this type had not been reported previously.Molecular modelling was utilised to evaluate and predict the coordinating potential of the macrocycles investigated.An alternative synthetic strategy was needed to achieve coordination complexes with titanium. This involved the use of a benzene based solvent system and rigorously dry reaction conditions.The final part of the work involved a detailed study of the kinetics of the hydrolysis of the titanium complexes investigated.
