Abstract

(Chemical Equation Presented) Going ferryl: Fe^II 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 {Fe^IV=O} complex is postulated to be the oxidant, formed by the homolytic cleavage of the O-O bond of an {Fe^III-OOH} intermediate. Performing the reaction under argon gives a mixture of cis and trans diols as well as the epoxide.
