Template assisted small molecule activation with s-/p-block bimetallics

该提案描述了模板辅助小分子活化与s-/p-嵌段双金属的概念化，用于生成新的主基团基材料。简而言之，工作方案一般可分为四个部分。下面，我们将按照各自的主要目标对它们进行详细的概述。第一部分是具有弱配位阴离子的s-嵌段金属盐的合成。这主要包括新的同系物[Al(OTf)4]-的合成，这是一种弱配位阴离子，对于难以捉摸的主基团化合物的稳定几乎没有探索过。第二部分，遵循低价13族元素化合物的附着，生成新的杂双金属化合物。即将合成的系列双金属化合物包括Li+ - Cs+、Mg2+ - Ba2+以及s嵌段相关离子Zn2+与Al(I)和Ga(I)的组合。双金属化合物作为同感复合物的功能，最终用于激活第三包中的小分子。在FLP化学之后，s-嵌段介质用于强制寡聚化反应，如Ph-CN、Ph-NC、Ph-CNO、CO2和其他小分子。有了这些基于主基团的大环，主基团材料的合成最终在碱诱导的开环聚合反应中被仔细研究，作为第四个工作包的一部分。

The given proposal describes the conceptualizaiton of a template assisted small molecule activation with s-/p-block bimetallics for the generation of novel main-group based materials.In a nutshell, the work programme can generally be divided into four parts. In the following, these are outlined precisely along the respective main aims.The first part will be the synthesis of s-block metal salts with weakly coordinating anions. This primarily includes the synthesis of the novel congener [Al(OTf)4]-, a weakly coordinating anion which is virtually unexplored regarding the stabilization of elusive main-group compounds. In the second part, it follows the attachment of low-valent group 13 element compounds to generate novel heterobimetallic compounds. The series of bimetallics which is about to be synthesized includes combinations of the ions Li+ - Cs+, Mg2+ - Ba2+ as well as the s-block related ion Zn2+ with Al(I) and Ga(I). Bimetallics as a function of homoleptic complexes are eventually used for the activation of small molecules in the third package. s-block mediation is used to enforce oligomerization reactions here following FLP chemistry such as with Ph-CN, Ph-NC, Ph-CNO, CO2 and further small molecules. With these main-group based macrocycles in hand, the synthesis of main-group materials is eventually scrutinized in base-induced ring-opening polymerization reactions as part of the fourth working package.
