Chemistry Beyond the Cyano Ligand: Shape Control of Cyano Compound with Lewis Acid Scaffolds Towards Stabilize Metal Cyanoradical (M(CN2-))

氰化物被认为是不反应的，像卤素一样，然而，在特定条件下，它可以表现为非无辜配体，即，接受电子（CN ^2-）。这种不清白的情况没有得到调查。我们建议回答这样一个问题：当M-CN^-被简化为“M-CN^2-”时，有什么准则？我们将研究含有氰化物的体系，该体系通过用与氰化物配体的N原子结合的刘易斯酸封端配体来保护。此外，我们计划通过创造一种可以与两个氰化物结合的分子来控制二氰基复合物的几何形状，类似于自然界与氰化物配体的相互作用。

Cyanide is considered unreactive, like a halogen, however, under specific conditions it may behave as a non-innocent ligand, i.e., accept electrons (CN^2-). This non-innocence has not been investigated. We propose to answer the question: What are the guidelines where M-CN^- is reduced to “M-CN^2-“ character? We will study systems containing a cyanide protected by capping the ligand with a Lewis acid bound to the N atom of the cyanide ligand. Additionally, we plan to control the geometry of the dicyano complexes by creating a molecules that can bind to two cyanides, similar to how nature interacts with cyanide ligands.
