Abstract

Abstract Hydroquinone and methoxybenzene derivatives were catalytically oxidized promptly to the corresponding quinones in up to 99% yield. With a catalyst loading of 0.01 mol%, a maximum TON of 8.4× 10 3 was attained in the case of Ru (II)-complex. Ru (II)(pybox-dh)(pydic) is able to enhance the hydrogen peroxide oxidation of substituted hydroquinones as well as methoxybenzenes, but Ir [(coe) 2 Cl] 2 and Ir [(cod) Cl] 2 were ...
