AI Article Synopsis
- - A new ferrous corrole complex, [Fe(ttppc)] (1), is reported to effectively bind dioxygen, leading to the formation of an η-superoxo complex, [Fe(O)(ttppc)] (2).
- - This complex showcases a distinct O-isotope sensitive ν(O-O) stretch at 1128 cm and a ν(Fe-O) stretch at 555 cm, confirming its structural properties.
- - Notably, [Fe(O)(ttppc)] (2) is the first well-characterized Fe-O corrole and plays a crucial role in important biological oxidation reactions, including the dioxygenation of indole derivatives and H-atom abstraction from O-H bonds.
Article Abstract
A new structurally characterized ferrous corrole [Fe (ttppc)] (1) binds one equivalent of dioxygen to form [Fe (O )(ttppc)] (2). This complex exhibits a O -isotope sensitive ν(O-O) stretch at 1128 cm concomitantly with a single ν(Fe-O ) at 555 cm , indicating it is an η -superoxo ("end-on") iron(III) complex. Complex 2 is the first well characterized Fe-O corrole, and mediates the following biologically relevant oxidation reactions: dioxygenation of an indole derivative, and H-atom abstraction from an activated O-H bond.
