The Lewis basicity of transition metal complexes forms a foundation of both inorganic chemistry and catalysis, however, unambiguous examples of Lewis adducts based on transition metal Lewis bases are still very rare. This proposal requests renewal of our previous DFG grant (2011-2014) related to dative bonds between main groups and transition metals, during which we elaborated on the concept of metal-only Lewis pairs (MOLPs). This project witnessed the significant expansion of the range of both Lewis base and acid components suitable for forming MOLPs, a number of borderline cases, and in some cases unusual alternative reaction outcomes. The scope of MOLP reactivity was also considerably widened. The future work proposed herein takes two distinct directions. Subproject A: Development of new Lewis acid and base components, their combination to form MOLPs, and further reactivity and spectroscopic studies to better understand the nature of metal-to-element dative bonds. Subproject B: The use of dynamic metal-to-element dative bonds as structural elements for supramolecular chemistry, a type of bond never before used in this field. This subproject aims to first develop synthetic routes to multitopic Lewis acid and base building blocks, and their combination to construct proof-of-principle supramolecular assemblies.

过渡金属配合物的刘易斯碱性是无机化学和催化的基础，然而，基于过渡金属刘易斯碱的刘易斯加合物的明确例子仍然非常罕见。该提案要求更新我们之前的DFG资助（2011-2014），该资助与主族和过渡金属之间的配价键有关，在此期间，我们详细阐述了金属刘易斯对（MOLP）的概念。该项目见证了适用于形成MOLP的刘易斯碱和酸组分的范围的显著扩展，许多临界情况，以及在某些情况下不寻常的替代反应结果。MOLP反应性的范围也大大拓宽。本文提出的未来工作有两个不同的方向。次级项目A：开发新的刘易斯酸和碱组分，它们的组合形成MOLP，并进一步进行反应性和光谱研究，以更好地了解金属与元素配价键的性质。子项目B：使用动态金属-元素配价键作为超分子化学的结构元素，这是一种从未在该领域使用过的键。该子项目旨在首先开发多主题刘易斯酸和碱构建块的合成路线，以及它们的组合来构建原理验证的超分子组装体。
