Abstract

Abstract: Herein, we report a new tripodal tris‐benzimidazole ligand (Tbim ) that structurally mimics the 3‐His coordination environment of certain nonheme mononuclear iron oxygenases. The coordination chemistry of Tbim was explored with iron(II) revealing a diverse set of coordination modes. The aerobic oxidation of biomimetic model substrate diethyl‐2‐phenylmalonate was studied using the Tbim −Fe and Fe(OTf)2 .
