Abstract
ABSTRACT The synthesis of Ni (II) complexes with pro-oxidant applications has demonstrated many advantages, such as accelerated reactions, solution stability and with high selectivity reactions. In this work we describe the synthesis, characterization and structural analysis of nickel ([(Ni)(C30H28N4O4S2)]);([(Ni)(C31H30N4O4S2)]) and ([(Ni)(C33H37N4O4S2)]·DMF — complex 3) complexes with ligands obtained from the condensation of pyridoxal and aryl-thiol amines and their application as a pro-oxidant in the reaction of the phenol-aminoantipyrine adduct. The complexes show variation in carbon spacers between pyridoxal molecules: ethane, propane and butane. It was found that the spacer two carbons containing the most significant as the pro-oxidant activity.
