Abstract

AbstractA 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.
