对苯二酚和甲氧基苯衍生物在催化剂作用下迅速氧化成相应的醌类化合物，产率高达99%。在Ru（II）-络合物的情况下，在0.01摩尔%的催化剂负载下，获得8.4 × 10（3）的最大TON。Ru（II）（pybox-dh）（pydic）能够增强取代对苯二酚和甲氧基苯的过氧化氢氧化，但Ir[（coe）（2）Cl]（2）和Ir[（cod）Cl]（2）在类似的氧化条件下仅对前者是有效的催化剂。
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 x 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 found to be effective catalysts only for the former substrates under similar oxidation conditions.
