Abstract
Two binary and two ternary mono‐oxovanadium (IV) complexes of acetylacetonate, curcumin and N,N′‐bis(2‐pyridyl)thiourea were synthesized. They were characterized using elemental analysis, infrared and UV–visible spectroscopies and magnetic and conductivity measurements. The formation constants Kf were determined from spectrophotometric measurements. The catalytic potential of the VO complexes was investigated for the oxidation of 1‐octene by aqueous H2O2 in acetonitrile. They display high catalytic potential for the conversion of 1‐octene with low chemoselectivity to the epoxy product. The VO complexes exhibit good antibacterial and antimicrobial activities. The antioxidant activity of the VO complexes and their ligands was investigated. The VO complexes show high DNA affinity and DNA cleavage ability.
