Аннотация: Osmium derivatives are much less popular among catalytic chemists in comparison with, for example, compounds of iron (an analog of osmium), copper, manganese+ Indeed, this metal is expensive, poisonous and volatile. Nevertheless, osmium finds applications not only in cis-hydroxylation of olefins but more recently, derived complexes have been employed in oxygenation of C‒H compounds (saturated and aromatic hydrocarbons and alcohols) by hydrogen peroxide as well as organic peroxides. The turnover numbers in alkane oxidations catalyzed by soluble osmium derivatives have been found to be much higher in comparison with analogous reactions induced by complexes of other transition metals (e.g., iron, manganese or copper). The authors of the present review, using certain additives, developed osmium-containing systems that extremely efficiently transform alkanes into corresponding alkyl hydroperoxides which can be further easily reduced to alcohols. These new catalytic systems described here are record holders in the field of metal-complex catalysts.
