N2 - A new structurally characterized ferrous corrole [FeII(ttppc)]− (1) binds one equivalent of dioxygen to form [FeIII(O2−.)(ttppc)]− (2). This complex exhibits a 16/18O2-isotope sensitive ν(O-O) stretch at 1128 cm−1 concomitantly with a single ν(Fe-O2) at 555 cm−1, indicating it is an η1-superoxo (“end-on”) iron(III) complex. Complex 2 is the first well characterized Fe-O2 corrole, and mediates the following biologically relevant oxidation reactions: dioxygenation of an indole derivative, and H-atom abstraction from an activated O−H bond.
