Bis(diethylamino)pentafluoroethylphosphane represents a versatile starting material for the synthesis of functionalized pentafluoroethylphosphanes. Perfluoroalkyl substituted aminophosphanes themselves already exhibit interesting coordination properties and were treated with the catalytically relevant salts PtCl2 and PdCl2 affording trans‐[Cl2MP(C2F5)(NEt2)2}2]. The hitherto unknown (C2F5)PBr2, accessible
双(二乙氨基)五氟乙基膦烷代表了一种多功能的原料,用于合成功能化的五氟乙基膦烷。全氟烷基取代的氨基膦烷本身已经显示出令人感兴趣的配位性能,并用催化相关的盐PtCl 2和PdCl 2处理,得到反-[Cl 2 M P(C 2 F 5)(NEt 2)2 } 2 ]。迄今未知的(C 2 F 5)PBr 2,可通过处理C 2 F 5 P(NEt 2)以高收率获得2用HBr平稳地转化为相应的膦C 2 F 5 PH 2或氟代衍生物C 2 F 5 PF 2。C 2 F 5 P(NEt 2)2的酸水解产生次膦酸C 2 F 5 P(O)(OH)H,其阴离子在结构上得到了表征。次膦酸在PC键的形成下平滑地加到丙酮的羰基上。与醛类(例如水杨醛)的类似反应提供了生成立体中心的可能性。

angstrom and re(P-O) = 1.582(3) angstrom for (C2F5)2POH. The different coordination properties of (C2F5)3P, (C2F5)2POH, (CF3)3P and (CF3)2POH were evaluated by complex formation with [Ni(CO)4]: the maximum achievable number of CO ligands substituted by (C2F5)3P is 1, by (C2F5)2POH is 2, by (CF3)3P is 3 and by the smallest ligand (CF3)2POH is 4.
