The new heteropolyperoxometalate compounds [NMe4][(Me2AsO2){MoO(O2) 2}2] 1, [NMe4][(Ph2PO2){MoO(O2) 2}2] 2, [NBun4][(Ph2PO2){WO(O 2)2}2] 3 and [NH4][(Ph2PO2){MoO(O2) 2(H2O)}] 4 have been isolated and their crystal structures determined. Compounds 1-3 are dinuclear, whilst compound 4 is mononuclear; in all four structures the metal centre(s) have essentially identical pentagonal-bipyramidal co-ordination geometries with a weak axial ligand trans to an oxo group. The utility of 3 as a catalyst for the oxidation of alkenes, alcohols and tertiary amines with hydrogen peroxide as cooxidant has been studied.
Heteropolyperoxo- and Isopolyperoxo-tungstates and -molybdates as Catalysts for the Oxidation of Tertiary Amines, Alkenes and Alcohols

The catalytic oxidation of tertiary amines to the corresponding N-oxides by 4>(3-) (X = P or As, M = Mo or W) and by (2-) with H2O2 as co-oxidant has been studied.Epoxidation of alkenes and oxidation of alcohols by (2-) with H2O2 as co-oxidant has also been examined and compared with that effected by 4>(3-).A possible structure for (2-) is suggested.
