Fluorinated Acyclic and Heterocyclic Nitrogen and/or Phosphorus-Containing Compounds

无机、生物无机和有机金属化学项目的这个项目的目标是合成和表征各种新的含氟氮和/或磷化合物。与不含氟的类似物相比，氟的存在将使新化合物具有理想的性质，例如特殊的高温稳定性和伴随的高密度和长液体范围。合成的目标化合物有三个族：(A)氟化环磷腈和聚磷腈；(B)氟化四氮唑和其他四氮-5元环体系；(C)氟化高氮化合物。许多新化合物将通过类似于用于无氟类似物的程序合成，但使用含氟的起始材料。在其他情况下，氟化可以用羰基氟或氧化三氟胺来完成。新化合物将通过各种光谱方法以及x射线和电子衍射结构技术进行表征。

The goal of this project in the Inorganic, Bioinorganic and Organometallic Chemistry Program is the synthesis and characterization of a wide variety of new fluorine-containing nitrogen and/or phosphorus compounds. It is expected that the presence of fluorine will endow the new compounds with desirable properties, such as special high temperature stabilities and concommitant high densities and long liquid ranges, compared to nonfluorinated analogs. The target compounds for synthesis are in three families: (A) fluorinated cyclophosphazenes and polyphosphazenes; (B) fluorinated tetrazoles and other tetraza-5-membered ring systems; and (C) fluorinated high-nitrogen compounds. Many of the new compounds will be synthesized by procedures analogous to those used for nonfluorinated analogs, but using fluorinated starting materials. In other cases fluorination will be accomplished with either carbonyl fluoride or trifluoroamine oxide. The new compounds will be characterized by a variety of spectroscopic methods and by x-ray and electron diffraction structural techniques.
