Aerobic epoxidation of olefins catalyzed by iron complexes without the use of a sacrificial coreductant is unknown. We report the reductive activation of O by a bioinspired [(bTAML)Fe(HO)] (1) complex to catalyze the epoxidation of alkenes with TONs of up to 80. Spectroscopic and kinetic evidence indicates the involvement of Fe(O) as the active oxidant during the reaction.
铁配合物在不使用牺牲性共还原剂的情况下催化烯烃的有氧环氧化反应尚属未知。我们报道了一种受生物启发的[(bTAML)Fe(HO)] (1)配合物对O的还原活化作用，以催化烯烃的环氧化反应，其转换数高达80。光谱和动力学证据表明，Fe(O)作为活性氧化剂参与了反应。
