Abstract: A new water-soluble copper(II) complex bearing 4-bromobenzoate/2,2?-dipyridylamine ligands was successfully synthesized and characterized by using single crystal X-ray diffraction and spectroscopic techniques. The catalytic activity of the compound was investigated as a homogeneous catalyst in the oxidation of several alcohols (benzyl alcohol, cinnamyl alcohol, 1-phenylethanol, cyclohexanol, 1-heptanol) and alkenes (styrene, ethylbenzene, cyclohexene) in aqueous medium. The copper(II) catalyst was found to be active for the studied alcohols and alkenes. H 2O 2 was used as an active oxidant for alcohol oxidation, while t-BuOOH (TBHP) was used for alkenes. The compound exhibited high selectivity toward benzaldehyde (88%) in cinnamyl alcohol oxidation under mild conditions (70 ?C) after 4 h. Particularly, remarkable results were obtained for the oxidation of styrene and cyclohexene; transformation via allylic oxidation to 2-cyclohexene-1-one as one product in 2 h (TOF=50h-1) and benzaldehyde in 1 h (100% conversion, TOF = 86 h – 1, 100% selectivity). The Cu(II)/TBHP (or H 2O 2) / H 2O system proved to be an alternative for catalytic oxidations in the green chemistry concept. Graphical Abstract: New Copper(II)-complex bearing 4-bromobenzoate/2,2?-dipyridylamine ligands was synthesized and characterized by single crystal diffraction technique. The complex exhibited good catalytic oxidation activity on alcohols and alkenes in water, a green solvent. [Figure not available: see fulltext.].

The interaction of the complexes with serum albumins was investigated by fluorescence emission spectroscopy and the corresponding binding constants were calculated. UV-Vis spectroscopy, viscosity measurements and fluorescence emission spectroscopy for the competitive studies of the complexes with ethidium bromide were the techniques used in order to investigate the interaction of the complexes with calf-thymus DNA; intercalation was revealed as the most possible mode of DNA-binding.
