摘要:
Saturated hydrocarbons such as adamantane, cyclooctane, cyclohexane, hexane and heptane are oxygenated by t-butylhydroperoxide (TBHP) or hypochlorite in the presence of the homogeneous catalysts K5[Ru(H2O)PW11O39] and cis-[Ru(H2O)2(dmso)4](BF4)2. With the latter a free-radical mechanism appears to dominate when TBHP is employed, thus accounting for the remarkably high rates of alkane conversions (up to ca. 8 turnovers per minute). Hypochlorite oxygenations proceed via oxo-metal species.
