Addition of bis(pentafluorophenyl)phosphinousacid to α,β-alkenones and α,β,β’-alkene-diones in anhydrous Et2O (the solvent, in which the P-OH tautomeric form predominates) proceeds rapidly and regiospecifically at the C=C bond of the substrate at room temperature in the absence of catalysts. The reaction leads to bis(pentafluorophenyl)phosphorylated alkanones and alkanediones, as a rule, in the yields
在无水 Et2O(溶剂,其中 P-OH 互变异构形式占主导地位)中,将双(五氟苯基)次膦酸添加到 α,β-烯烃和 α,β,β'-烯烃-二酮中,在 C= 处快速且区域特异性地进行在没有催化剂的情况下,基材在室温下的 C 键。该反应产生双(五氟苯基)磷酸化烷酮和烷二酮,通常收率接近定量,可被视为合成相应官能化氧化膦的高效方法。所得化合物的结构通过红外光谱和核磁共振光谱以及X射线衍射分析确定。
In this paper a safe one step and high yield synthesis of (CF3)2POH is described. The compound (C6F5)2POH, originally claimed as a phosphinousacid, is proved to exist at room temperature exclusively in the tautomeric oxide form. (C6F5)2P(O)H crystallizes in the triclinic space group P1¯ (no. 2) with a 992.9(1) pm; b 1501.9(2) pm; c 1539.4(2) pm; α 117.48(1)°; β 100.39(1)°; γ 96.02(1)° and Z 6.
有机元素化合物的电子特性受有机替代物的电子特性的强烈影响。两个CF 3基团与磷原子的键合使碱性大大降低。即,磷原子是化合物(CF 3)2 POH中的最低碱性中心。该化合物由Burg和Griffiths于1960年合成,是次膦酸的唯一已知实例,尽管这类化合物应引起人们的普遍关注。但是,仅报道了一些调查,这些调查可以通过乏味而危险的综合来解释。在本文中,描述了一种安全的一步法和高收率的(CF 3)2 POH合成方法。化合物(C.6 F 5)2 POH原本被称为次膦酸,已证明在室温下仅以互变异构形式存在。(C 6 F 5)2 P(O)H在三斜空间群P1中结晶(无)。 2)用一个992.9(1)时; b 1501.9(2)下午; c 1539.4(2)pm; α 117.48(1)°; β 100.39(1)°; γ 96.02(1)°和Ž 6。

The interaction of a series of acrylic and cinnamic acid amides with bis(pentafluorophenyl)-phosphinic acid proceeds vigorously at room temperature without any catalyst in the presence of the organic solvents providing for a high fraction of the > P-OH tautomer of the phosphinic acid. The reactions have afforded (2-carbamoylethyl)bis(pentafluorophenyl)phosphine oxides in a high yield.
