The mechanistic investigation of copper-catalysed transformations has been an important and fundamental task. Herein, we report via XAS and EPR spectroscopy that the sodium bis(trimethylsilyl)amide could reduce Cu(II) to a Cu(I) species serving as an electron donor. XAS spectroscopy demonstrates that the newly formed Cu(I) species is the Cu[N(TMS)₂]₂Na ate complex, in which the nitrogen atoms coordinate with copper linearly.

揭示双（三甲基甲硅烷基）酰胺钠对Cu（ii）的还原过程†

铜催化转化的机理研究一直是重要而基本的任务。在这里，我们通过XAS和EPR光谱报告，双（三甲基甲硅烷基）酰胺钠可以将Cu（II）还原为充当电子供体的Cu（I）物种。XAS光谱表明，新形成的Cu（I）物种是Cu [N（TMS）₂ ] ₂ Na ate配合物，其中的氮原子与铜呈线性配位。
