Nitrogen containing derivatives of diacetyl and their use as ligands

TL;DRAbstract

The main objective of this thesis is to synthesise and examine the chelating properties of substituted dihydrazones of diacetyl, CH3C(0)C(0)CH3. The synthesis, structures, spectroscopic and electrochemical properties of the substituted dihydrazones and their metal complexes are described.\n\nChapter I provides a general introduction to the chemistry of substituted dihydrazones and describes the advantages of their use as coordinating ligands over more commonly studied ligands such as 2,2-bipyridine (bipy). A review of previously reported metal complexes of substituted dihydrazones of diacetyl and their applications is described.\n\nThe synthesis and characterisation of a series of substituted mono- and dihydrazones of diacetyl including the preparation of some novel asymmetric dihydrazones are described in chapter II. The development of a new synthetic route for the preparation of azine oligomers of discrete sizes, H2N-[-N=C(CH3)-C(CH3)=N-]n-NH2 (for n = 1 to 5), where n is the number
