The reaction of MoO3 [or “WO3 · H2O”], aqueous H2O2 (30 wt%) with R 2 Si ( OR ′ ) 2 in alkaline hydrogen peroxide–ethanol mixtures followed by treatment with PPh4+Cl− affords the corresponding salts of the previously unknown dioxotetrapero

The Keggin dodecatungstoarsenato anion of HNa2[AsW12O40] is inherently unstable in aqueous hydrogen peroxide and is mainly degraded to [AsO4{W2O2(-O2)2(O2)2}2]3-, [HAsO4{W2O2(-O2)2(O2)2}]2- and [{WO(O2)2(H2O)}2(-O)]2-. These anions were isolated as s

In the presence of catalytic quantities of [MoO2Cl2L] (L=β-ketophosphonate derived from camphor), water initiates the selective ring opening of cis (+) or (−)-limonene oxide to give the trans-diaxial diol. The trans isomer of the limonene oxide re
