Graphical Abstract

Zweierlei Reaktivität zeigt eine HOFeVO-Spezies bei der Fe(tpa)-katalysierten Oxidation von Olefinen (tpa=Tris(2-pyridylmethyl)amin). Greift der Oxoligand an einem olefinischen Kohlenstoffatom an, so entsteht das Epoxid, ist es der Hydroxoligand, so wird das cis-Diol gebildet (siehe Schema). Hybrid-Dichtefunktionalrechnungen ergaben vergleichbar hohe Aktivierungsenergien für die beiden Reaktionen.
