Abstract

A neutral trans-dioxoosmium(vi) complex [OsO₂(CN)₂(dp-phen)] (dpphen = 4,7-diphenyl-1,10-phenanthroline) is prepared and characterized by X-ray crystal analysis; the excited state is long-lived, emissive and oxidizing [E°(Os^VI-V) = 2.15 V vs. NHE; lifetime = 0.95 μs; quantum yield = 5 × 10^-4; λ_em(max.) = 650 nm]; under UV-VIS irradiation and in the presence of dioxygen, cyclohexane is oxidized to cyclohexanol and cyclohexanone with a turnover number of 16; secondary C-H bonds of propane and primary C-H bonds of n-hexane are also oxidized.
