Alkanes such as adamantane, ethylbenzene and cyclohexane, cyclohexene, and aldehydes are selectively oxidized to the corresponding alcohols, ketones, and acids with molecular oxygen alone catalyzed by the Fe(3-x)Ni(x)-substituted Keggin-type heteropolyanion, [PW9O37{Fe(3-x)Ni(x)(OAc)3}](9+x)- (x = predominantly 1). The catalytic activities of [PW9O37{Fe(3-x)Ni(x)(OAc)3}](9+x)- for the oxidation of cyclohexane and butyraldehyde were compared with mono-transition-metal substituted heteropolytungstates and other compounds having oxo-bridged tri-transition-metal sites. In addition, the effects of acetonitrile as a solvent and the addition of isobutyraldehyde were investigated.
