First row transitionmetalsubstituted polyfluorooxmetalates with quasi Wells–Dawson structures and a nitro terminal ligand, [NaH2M(NO2)W17F6O55]q−, were used as catalysts for the aerobic epoxidation of cyclic alkenes. The Cu(NO2) analog combined the best traits of conversion and selectivity. Some C–C bond cleavage was also observed and cis isomers reacted preferentially without stereochemical inversion
