Iron(II) perchlorate in an H₂O-H₂O₂-CH₃CN mixture was used to efficiently carry out CH bond activations of benzene to form phenol and/or hydroquinone, and of toluene to form benzaldehyde, benzyl alcohol, o-cresol, p-cresol, and/or methyl-p-benzoquinone. The reactions were facilely tuned and controlled to selectively yield either a single or double oxygenation of benzene as well as a sp³ or sp² CH bond oxidation of toluene. On the basis of H/D kinetic isotope effect data, we determined the aromatic oxidation to mostly proceed by way of formation of an arene oxide or a σ-complex intermediate from high-valence iron species and to then undergo a 1,2-hydride shift, i.e., NIH-shift rearrangement.

铁（II），高氯酸中的H ₂ O - H ₂ ö ₂ -CH ₃ CN混合物用于至C有效地进行苯的H键激活以形成苯酚和/或氢醌，和甲苯以形成苯甲醛，苄醇，ö -甲酚，对甲酚和/或甲基对苯醌。可以轻松调节反应并进行控制，以选择性产生苯的单次或双次氧化以及sp ³或sp ² C甲苯的H键氧化。根据H / D动力学同位素效应数据，我们确定了芳族氧化反应主要是通过从高价铁物种形成氧化芳烃或σ-复杂中间体而进行的，然后进行1,2-氢化物移位，即NIH移位重排。
