摘要：

(Chemical Equation Presented) Going ferryl: FeII complexes with two isomeric bispidine ligands catalyze the oxidation of cyclooctene with H 2O2 in MeCN under aerobic conditions with high selectivity for the epoxide (see scheme; L = bispidine ligand). An {FeIV=O} complex is postulated to be the oxidant, formed by the homolytic cleavage of the O-O bond of an {FeIII-OOH} intermediate. Performing the reaction under argon gives a mixture of cis and trans diols as well as the epoxide. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
