Abstract:
This thesis deals with the synthesis, characterisation and
catalytic activity studies of some new transition metal complexes of the
Schiff bases, derived from quinoxaline—2—carboxaldehyde. The model
complexes derived from specially designed and synthesised Schiff bases
help us to understand the chemistry of biological systems. Schiff bases
derived from heterocyclic aldehydes like quinoxaline-2-carboxaldehyde
provide great structural diversity during complexation. The Schiff
bases synthesised in the present study ' are
quinoxaline—2—carboxa.lidene-2-aminophenol (QAP). quinoxaline—2carboxaldehyde
semicarbazone (QSC), quinoxaline-2—carboxalidene—o—
phenylenediamine (QOD) and quinoxaline-2-carboxalidene-2-furfurylamine
(QFA). The elucidation of the structure of these complexes is done
using conductance, magnetic susceptibility measurements. infrared,
UV—Vis and EPR spectral studies.
