Osmium-(III) and -(IV) complexes of the ligands salen , bpb and bpc were synthesised by reducing the corresponding trans-dioxoosmium(VI) complexes with PPh3.The structure of IV(salen)(OPri)2> has been detremined by X-ray crystallography: monoclinic, space group C2/c (no. 15), a = 15.367(2), b = 7.847(1), c = 17.999(2) Angstroem, β = 95.36(1) deg and Z = 4.Electrochemical studies of trans-dialkoxyoosmium(IV) complexes in acetonitrile showed a reversible oxidation wave assignable to the oxidation of OsIV to OsV.Some trans-dialkoxyoosmium(V) complexes were characterised by UV/VIS spectroscopy.The osmium(III) complexes of salen, bpb and bpc were found to catalyse the oxidation of alkenes by iodosylbenzene.
