Low-Temperature Conversions of Complex Solid Precursors in Ionic Liquids: New Compounds and Insights into Reaction Principles

在上一个资助期，我们已经证明，合成和光谱技术的组合是非常有价值的离子液体（ILs）的反应机制的评估。因此，我们将在第二个资助期内继续德累斯顿工业大学Ruck组（无机化学）和Brunner组（分析化学）的成功联合研究，并专注于离子液体反应的原位监测和通过先进的固态NMR光谱对反应产物进行深入表征。特别重要的是以下问题：哪种起始物料被IL动员？如何启动动员或解散？离子液体中的支持剂（如刘易斯酸或酸性杂质）的作用是什么？大众运输是如何进行的？如何在原子/分子尺度上形成产物？它是如何发展到最终产品颗粒的形成的？这些结果将有助于更深入地了解在原子/分子尺度上的电离合成，并允许确定的参数，至关重要的影响反应。这应该允许更有针对性的方法，并使我们能够选择性地进行材料合成，并具有高产率。特别是，我们的目标是开发一个（至少是原油）的一般策略，适用于合成的过渡金属和元素的第13至16族离子液体的二元化合物。

In the previous funding period, we have demonstrated that the combination of synthetic and spectroscopic techniques is extremely valuable for the evaluation of reaction mechanisms in ionic liquids (ILs). We will therefore continue the successful joint research of the Ruck group (Inorganic Chemistry) and the Brunner group (Analytical Chemistry) at TU Dresden in the second funding period and focus on the in-situ monitoring of reactions in ILs and the in-depth characterization of reaction products by advanced solid-state NMR spectroscopy. Of special importance are the following questions: Which starting material is mobilized by the IL? How is the mobilization or dissolution initiated? What is the role of supporting agents, such as Lewis acids or acidic impurities in the ILs? How does the mass transport proceed? How does product formation start at the atomic/molecular scale? How does it progress to the formation of the final product particles?The results will contribute to a deeper understanding of the ionothermal syntheses at the atomic/molecular scale and allow the determination of parameters that crucially influence the reactions. This should allow for a more targeted approach and enable us to perform materials synthesis selectively and with high yields. In particular, we are aiming to develop a (at least crude) general strategy that is applicable for the synthesis of binary compounds of transition metals and elements of the groups 13 to 16 in ILs.
