NO2 – Activation and Reduction to NO by a Nonheme Fe(NO2)2 Complex

The selective reduction of nitrite (NO2 –) to nitric oxide (NO) is a fundamentally important chemical transformation related to environmental remediation of NO x and mammalian blood flow. We report the synthesis and characterization of two nonheme Fe complexes, [Fe­(LN4 Im)­(MeCN)2]­(BF4)2 (1 MeCN )...

Description
Summary:The selective reduction of nitrite (NO2 –) to nitric oxide (NO) is a fundamentally important chemical transformation related to environmental remediation of NO x and mammalian blood flow. We report the synthesis and characterization of two nonheme Fe complexes, [Fe­(LN4 Im)­(MeCN)2]­(BF4)2 (1 MeCN ) and [Fe­(LN4 Im)­(NO2)2] (2), geared toward understanding the NO2 – to NO conversion. Complex 2 represents the first structurally characterized FeII complex with two axial NO2 – ligands that functions as a nitrite reduction catalyst.
