The direct decomposition of nitromethane into nitrile compounds is a significant challenge due to the occurrence of severe side-reactions. In this study, we present a novel and gentle methodology for converting primary nitromethane into nitriles using [Cp*RhCl₂]₂. This reaction stands out for its simplicity and convenience under mild conditions. Moreover, the resulting nitrile serves as a direct precursor for the construction of organometallic complexes 1–3, through treating with different equivalents of AgOTf. Additionally, we conducted a systematic investigation into the mechanism of this reaction, revealing that the presence of AgOTf plays a crucial role in the formation of diverse organometallic cages. To provide comprehensive characterization, we employed various techniques including IR spectroscopy, ¹H NMR spectroscopy, HRESI-MS measurements, and single-crystal X-ray diffraction (SCXRD).

硝基甲烷溶液中的异常反应：使用 Cp*Rh 部分形成普鲁士蓝类似物

由于会发生严重的副反应，硝基甲烷直接分解为腈化合物是一个重大挑战。在这项研究中，我们提出了一种使用 [Cp*RhCl ₂ ] ₂将伯硝基甲烷转化为腈的新颖且温和的方法。该反应因其在温和条件下的简单性和方便性而脱颖而出。此外，通过用不同当量的 AgOTf 处理，所得腈可作为构建有机金属配合物1-3的直接前体。此外，我们对该反应的机理进行了系统研究，揭示了AgOTf的存在在多种有机金属笼的形成中起着至关重要的作用。为了提供全面的表征，我们采用了各种技术，包括红外光谱、¹ H NMR 光谱、HRESI-MS 测量和单晶 X 射线衍射 (SCXRD)。
