Functionalized fluorinated carba-closo-borates and related boron clusters synthesis and reactivity of polyfluorinated boron cluster compounds

具有一个或多个官能团的多氟阴离子硼簇合物与具有其他卤素取代基的类似的非氟化簇合物和衍生物相比，表现出不同寻常的反应性。我们已经证明，这种不寻常的反应活性可以用于制备高氟化的硼团簇，这是其他合成方法所不能达到的。本项目的目的是进一步开发合成高氟化的含官能团的硼簇合物，研究新化合物的性质，并比较氟化簇合物与卤化簇合物的反应性。重点介绍了碳基-环十二硼和环-十一硼簇合物以及作为官能团的氨基和氰基取代基。该项目的另一个目标是使具有官能团的多氟闭硼阴离子可用作合成构筑块。

Polyfluorinated anionic boron clusters with one or more functional groups exhibit an unusual reactivity compared to the analogous non-fluorinated clusters and derivatives with the other halogen substituents. We have demonstrated that this unusual reactivity can be used for the preparation of highly fluorinated boron clusters, which are not accessible by other synthetic methods. The aim of this project is the further development of syntheses to result in highly fluorinated boron clusters with functional groups, the investigation of the properties of the novel compounds, and the comparison of the reactivity of the fluorinated clusters to those of the halogenated clusters with the heavier halogens. The focus is on carba-closo-dodecaboron and closo-undecaboron clusters and amino as well as cyano substituents as functional groups. A further aim of this project is to make polyfluorinated closo-borate anions with functional groups available as synthetic building blocks.
