  • Fluorotrimethyl[( <i>Z</i> )‐pentafluoropropen‐1‐yl]phosphorane: Structure, Bonding, and Reactivity

    In this contribution we report on fluorotrimethyl[(Z)‐pentafluoropropen‐1‐yl]phosphorane as a phosphorus based fluorinating reagent. Its solid state structure can be described as a trigonal bipyramid featuring elongated axial bonds due to the formation of a 3‐center 4‐electron bond. Abstraction of the fluoride ion leads to a shortening of the axial P–C bond. Thus the title compound can be utilized
    在此贡献中,我们报告了氟三甲基[(Z)-五氟丙烯-1-基]磷烷作为磷基氟化试剂。它的固态结构可以描述为三棱锥,由于形成了3中心4电子键,所以具有细长的轴向键。氟化物离子的提取导致轴向P–C键的缩短。因此,标题化合物可用于用氟取代溴,以及将氟离子转移到亲电子化合物上。与Sn(C 2 F 5)2 Br 2反应,得到盐[P(CH 3)3(C 3 F 5)] 2 [Sn(C 2F 5)2 F 4 ]。当用P(C 2 F 5)2 F处理氟代三甲基[(Z)-五氟丙烯-1-基]磷烷时,主要生成的阴离子具有足够的亲核性,可以攻击位于磷原子β位的阳离子的丙烯基产生两性离子[Me 3 PCF = C(CF 3)–PF 3(C 2 F 5)2 ]。

    The reaction with P(C2F5)3F2 afforded [Et2N=CF‐CHF‐CF3][P(C2F5)3F3] as an ionic liquid. The fluorine atom in the cation in α position to the nitrogen atom is labile towards nucleophilic substitution as demonstrated by the reaction with SnCl2 where an exchange of the fluorine by a chlorine atom took place. Upon contact with water the fluorine atom is substituted by a hydroxyl group. The reaction of Ishikawa's
    我们在此报告了源自Ishikawa试剂Et 2 N-CF 2 -CHF-CF 3的亚胺盐。与P(C 2 F 5)3 F 2反应,得到[Et 2 N = CF-CHF-CF 3 ] [P(C 2 F 5)3 F 3 ],为离子液体。与SnCl 2的反应表明,位于氮原子α位的阳离子中的氟原子对亲核取代反应不稳定。其中氯原子与氟发生了交换。与水接触时,氟原子被羟基取代。石川试剂与P(C 2 F 5)2 F的反应得到两性离子[P(C 2 F 5)2 F 3 C(NEt 2)(CHF-CF 3)}。最有可能[Et 2 N = CF-CHF-CF 3 ] [P(C 2 F 5)2 F 2]是瞬时形成的。阴离子显然具有足够的亲核性,可以攻击阳离子中易受影响的α-氟原子。在几个月的时间里,石川的试剂损失了氟化氢,它与玻璃反应生成SiF 4,该SiF 4从石川的试剂中提取了氟离子,从而提供了[Et 2 N

    尽管不同的金属四氟磷酰胺 M[PF 4 ] (M = Cs, Ag, K) 很容易分解,但我们通过用吸电子五氟乙基取代两个氟原子成功地增强了此类物质的稳定性。因此,AgF 与 P(C 2 F 5 ) 2 F相加,产生 Ag[P(C 2 F 5 ) 2 F 2 ],其用作合成单-、双-和三[二氟双(五氟乙基)正膦基]银配合物。添加 2,2'-联吡啶可以分离出稳定的 [Ag(bipy)P(C 2 F 5 ) 2 F 2}],而与氯化物 [NMe 4 ]Cl 和 CoCl 2 的反应提供了双和三磷氨基甲酸根 [NMe 4 ][AgP(C 2 F 5 ) 2 F 2 } 2 (OEt 2 )] 和 [Co (NCMe) 6 ][AgP(C 2 F 5 ) 2 F 2 } 3 ]·2MeCN。总之,二氟双(五氟乙基)正膦基部分用作新型的、小的、非环状的正膦基配体。它提供了对第一个均质磷胺金属络合物
