Nishida, Yuzo, Tadashi Tokii, and Izumi Watanabe. "Reaction between Superoxide Anion and Several Oxovanadium(IV) Compounds." Zeitschrift für Naturforschung B 47, no. 7 (1992): 905–10. http://dx.doi.org/10.1515/znb-1992-0701.

Abstract:
We have observed that the superoxide anion reacts with VO(salen), but not with VO(saldpt), where H2(salen) and H2(saldpt) are Schiff base ligands derived from salicylaldehyde and ethylenediamine or dipropylenetriamine, respectively. Based on the electrochemical, ESR, and UV spectroscopic studies of the reaction mixture, it was concluded that the superoxide anion reacts with VO(salen) to oxidize V(IV) to V(V) through the formation of a vanadium(V)-peroxide adduct with side-on configuration. The SOD-like function of VO(salen) was elucidated in terms of the above assumption.

Abstract:
Propylene carbonate can be used as a green solvent for the asymmetric synthesis of cyanohydrin trimethylsilyl ethers from aldehydes and trimethylsilyl cyanide catalysed by VO(salen)NCS, though reactions are slower in this solvent than the corresponding reactions carried out in dichloromethane. A mechanistic study has been undertaken, comparing the catalytic activity of VO(salen)NCS in propylene carbonate and dichloromethane. Reactions in both solvents obey overall second-order kinetics, the rate of reaction being dependent on the concentration of both the aldehyde and trimethylsilyl cyanide. T
