The present work describes the synthesis, characterization and the investigation of electrochemical
and catalytic performance of a series of new N2O2type oxidovanadium(IV) Schiff base complexes. The
Schiff base ligands had salophen type structure and were derived from the condensation of 4-methyl or 4-
nitro-1,2-phenylenediamine with salicylaldehyde. The catalytic ability of the complexes was studied in the
process of epoxidation of cyclooctene with tert-butylhydroperoxide (TBHP). Several factors affecting this
catalytic ability was optimized such as solvent type, catalyst amount, substrate to oxidant ratio, and
reaction time. Electrochemical studies revealed that in the presence of electron withdrawing groups, the
VIV/VV redox potentials shifted to more positive values. Besides, the catalytic performance of the
complexes was increased by this increase.
