Hydroxylation or ketonization of alkanes is achieved using lithium or sodium hypochlorite in the presence of catalytic amounts of ruthenium(II) complexes in a biphasic dichloromethane-water system, at room temperature. The oxidation of cyclooctane is first order both in substrate and in catalyst: a kinetic isotope effect (k(H)/k(D)) = 5.6 was measured using cyclohexane-d12. A discussion is included concerning the origin of the different regioselectivities.

Abstract
Hydroxylation or ketonization of alkanes is achieved using lithium or sodium hypochlorite in the presence of catalytic amounts of ruthenium(II) complexes in a biphasic dichloromethane-water system, at room temperature. The oxidation of cyclooctane is first order both in substrate and in catalyst: a kinetic isotope effect (k(H)/k(D)) = 5.6 was measured using cyclohexane-d12. A discussion is included concerning the origin of the different regioselectivities.File in questo prodotto:
