Fluoride is a widely distributed nephrotoxin with exposure potentially resulting from environmental fluorine excess.

肾脏是氟的主要排泄器官，当机体摄入过量氟超过肾的排泄能力时，肾组织细胞就会因处于高氟环境而受到损害。

The main research now is focused on the polymerization of difluoramino substituted oxetane monomers, the preparation of neopentyl difluoramino nitrato plasticizers, and the molecular design and synthesis of cyclic N2 nitramino geminal difluoramino oxidizers.

目前该领域的研究工作主要集中在二氟氨基取代环氧丁烷聚合物合成，新戊基二氟氨基硝酸酯增塑剂制备，以及环N2硝胺基偕二氟氨基氧化剂的分子设计与合成上。

In the presence of catalytic rhodium acetate, ethyl 2-diazo-3-oxo-per fluoroalkanoates, reacted readily with nitriles to give a series of 5-fluoroalkyl substituted 1, 3oxazoles with high regio-selectivity through a metal carbenoid intermediate. The reactions of carbenoids with noncyclic vinyl ethers or cyclic vinyl ethers afforded dihydrofuroates in good to excellent yields. Interestingly, only vinyl C-H insertion compound was obtained concerning of the reaction of carbenoids with 2, 5dimethylfuran due to the steric hindrance of methyl group

醋酸铑分解2-重氮-3-氧代-全氟羧酸乙酯形成的金属卡宾作为1，3-偶极体，可以与一系列芳基或烷基取代的腈反应，高度区域选择性地生成一系列4-乙氧羰基-5-氟烷基取代的噁唑化合物；也可以与富电子的链状和环状的烯基醚反应，以优良的产率得到一系列氟烷基取代的二氢呋喃类化合物；而与2，5-二甲基呋喃的反应，由于甲基的位阻作用，只得到金属卡宾对呋喃3-位烯基碳氢键插入产物。

The use of perfluorous nonene solvent allowed the formation of a fluorous biphase system with the ester products thereby driving the esterification equilibrium to move rightly.
