A review of the methods available for the preparation of monodentate P(III) compounds containing fluoroalkenyl, fluoroalkynyl and fluoroalkyl groups is given. The synthesis, properties and coordinationchemistry of some fluoroalkenyl- and fluoroalkynyl-containing phosphines derived from HFC-134a (CF3CH2F) and HFC-245fa (CF3CH2CH2F) is summarised. The development of the reaction between trimethylsilyl-containing
综述了可用于制备含有氟烯基,氟炔基和氟烷基的单齿P(III)化合物的方法。总结了一些衍生自HFC-134a(CF 3 CH 2 F)和HFC-245fa(CF 3 CH 2 CH 2 F)的含氟烯基和氟炔基的膦的合成,性质和配位化学。含三甲基甲硅烷基的膦与R f I之间反应的发展,这提供了一种通用的方法,通过该方法可以形成庞大的氟代烷基,例如i -C 3 F 7,t -C 4 F 9,据报道,c -C 6 F 11可以很容易地引入到磷(III)中心。这些方法共同提供了一种生成R 3− n P(R f)n类型的P(III)系统的方法,该系统具有广泛的空间和电子特性。

reported TFMPhos, products from nucleophilic or electrophilic trifluoromethylation of substrates, requiring one or more steps and prepared from phosphine chlorides, are very limited in structure diversity. Herein, we report a convenient and scalable (up to 100 mmol) recipe to synthesize diverse trifluoromethylphosphines via direct radical trifluoromethylation of phosphine chlorides with CF3Br in the presence
‘F'lurry of activity: The title reaction provides a convenient procedure for direct synthesis of perfluoroalkylated phosphines. The synthesized phosphine n‐C10F21PPh2 forms a complex with palladium(II) to give 1 and several runs of coupling reactions are attained with n‐C10F21PPh2 by using a fluorous/organic biphasic system.
活性的“ F”浆:标题反应为直接合成全氟烷基化的膦提供了便利的程序。合成的膦n- C 10 F 21 PPh 2与钯(II)形成配合物,生成1,通过使用氟/有机双相体系,n- C 10 F 21 PPh 2可以进行多次偶联反应。
