The selective reduction of nitrite (NO2(-)) to nitric oxide (NO) is a fundamentally important chemical transformation related to environmental remediation of NOx and mammalian blood flow. We report the synthesis and characterization of two nonheme Fe complexes, Fe(LN4(Im))(MeCN)22 (1(MeCN)) and [Fe(LN4(Im))(NO2)2] (2), geared toward understanding the NO2(-) to NO conversion. Complex 2 represents the first structurally characterized Fe(II) complex with two axial NO2(-) ligands that functions as a nitrite reduction catalyst.
亚硝酸盐(NO2(-))选择性还原为一氧化氮(NO)是与 NOx 环境修复和哺乳动物血流相关的一种非常重要的化学转化。我们报告了两种非血红素 Fe 配合物Fe(LN4(Im))(MeCN)22(1(MeCN))和[Fe(LN4(Im))(NO2)2](2)的合成和表征,旨在理解 NO2(-)到 NO 的转化。配合物 2 代表了第一个具有两个轴向 NO2(-)配体的结构特征明确的 Fe(II)配合物,它可作为亚硝酸盐还原催化剂。
