| 中文摘要 | Chiral bioinspired iron complexes of N4 ligands based on the ethylenediamine backbone display remarkable levels of enantioselectivity for the first time in the asymmetric epoxidation of a,b-unsaturated ketones using hydrogen peroxide (up to 87% ee) or peracetic acid as oxidant, respectively. Notablely, isotopic labeling with H2 18O strongly demonstrated that there is a reversible water binding step prior to generation of the significant intermediate. Besides, the complex [L2FeACHTUNGTRENUNG(III)2ACHTUNGTRENUNG(m-O)ACHTUNGTRENUNG(m-CH3CO2)]3+ usually derived from the decay of the LFe(IV)=O species or thermodynamic sinks for a number of iron complexes was identified by HR-MS. In addition, the possible mechanisms were proposed and LFe(V)=O species may be the main active intermediate in the catalytic system. |
