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.

该项目在无机、生物无机和有机金属化学计划中的目标是合成和表征各种新型含氟氮和/或磷化合物。与非氟化类似物相比，预计氟的存在将赋予新化合物所需的性能，例如特殊的高温稳定性以及随之而来的高密度和长液体范围。 合成的目标化合物分为三个家族：（A）氟化环磷腈和聚磷腈； (B)氟化四唑和其他四氮杂5元环系统； (C)氟化高氮化合物。许多新化合物将通过与非氟化类似物类似的程序合成，但使用氟化起始材料。在其他情况下，氟化可以用碳酰氟或三氟氧化胺来完成。新化合物将通过多种光谱方法以及 X 射线和电子衍射结构技术进行表征。
