Abstract
Abstract: The reduction of 0s(NH3)5(CF3S03)3 in methanol or aqueous solution affords the dihydrogen complex [Os-
(NH3)5(H2)]2+, [1]2+. The one-electron oxidation of this species generates a trivalent dihydrogen complex [1]3+ which, unlike
its precursor, is capable of hydrogenating acetone to isopropyl alcohol. The use of methanol as a solvent offers important
advantages for the preparation of a number of Os(II) complexes over other nonaqueous solvents previously used.
