The main objective of this project is to prepare and investigate low-valent group 13/15 compounds stabilized by NHC ligands.13/15 compounds tend to be to oligomerization, since both Lewis acid and Lewis basic atoms are present. Consequently, targeted stabilization and isolation of low-valent, monomeric compounds of this element combination has hitherto been achieved only in a few exceptional cases.In this project, the tendency to form oligomers is systematically suppressed by the use of NHC ligands which optionally coordinate to the Group 13 or Group 15 element. This makes it possible to access a new class of compounds whose structures, bonding and properties have so far been very little known. In the further course of the project, the findings from the investigated 13/15 compounds are to be used to determine other low-valent compound classes of the element combinations 14/15, 15/15 or even ÜM/15.

本项目的主要目的是制备和研究低价的13/15族化合物稳定的NHC配体。13/15族化合物倾向于低聚，因为刘易斯酸和刘易斯碱原子都存在。因此，迄今为止仅在少数例外情况下实现了该元素组合的低价单体化合物的目标稳定化和分离。在该项目中，通过使用任选与第13族或第15族元素配位的NHC配体，系统地抑制了形成低聚物的趋势。这使得有可能获得一类新的化合物，其结构，键合和性质迄今为止知之甚少。在该项目的进一步过程中，研究13/15化合物的结果将用于确定元素组合14/15，15/15甚至ÜM/15的其他低价化合物类别。
