Among a series of iron salts, iron triflates revealed as highly active catalysts for the oxidation of cyclohexane by tert ‐butyl hydroperoxide into cyclohexanol and cyclohexanone with initial turnover frequencies higher than 10,000 h^–¹. The coordination of the catalytic iron center readily evolved in the presence of the reaction products, ultimately deactivating it. Iron and organic superoxo intermediates were identified as plausible active species.

铁三氟甲磺酸盐作为环己烷无溶剂氧化的高活性催化剂

在一系列铁盐中，三氟甲磺酸铁是高活性催化剂，可将叔丁基氢过氧化物氧化成环己醇和环己酮，并将环己烷氧化为环己烷和环己酮，初始转化频率高于10,000 h ^–¹。在反应产物的存在下，催化铁中心的配位容易发展，最终使其失活。铁和有机超氧中间体被认为是合理的活性物质。
