elimination of oxygen by the reaction of HFA with N=WCl3 may be considered as a new Wittig type reaction. The dimer of hexafluorothioacetone inserts into its SC bond the carbon atom of an isonitrile group to yield five-membered rings. PCl5 adds to (CF3)2CC(CN)2, prepared from HFA and CH2(CN)2, to form a six-membered phosphorus containing ring.

Several new phosphoranides of the type [NR4][PR′(CN)2X](R′= Me, Et, Ph, or C6F5; X = Cl, Br, I, or NCS) have been synthesised, and characterised by means of 31P n.m.r. spectroscopy, elemental analysis, and (in some cases) i.r. spectroscopy. These are the first simple phosphoranides to be prepared with an organo group bound directly to phosphorus. Determination of the crystal structure of [Net4][PPh(CN)2Cl]
已合成了[NR 4 ] [PR'(CN)2 X](R'= Me,Et,Ph或C 6 F 5; X = Cl,Br,I或NCS)类型的几种新的磷酰胺,并通过31 P nmr光谱,元素分析和(在某些情况下)ir光谱进行表征。这些是要制备的第一个简单的带有直接与磷结合的有机基团的磷酰胺。对[Net 4 ] [PPh(CN)2 Cl]的晶体结构的测定表明,该阴离子具有扭曲的单体ψ-三角双锥体几何结构,具有苯基基团赤道和一个非常长的P-Cl轴向键,如先前观察到的在[PCl 4 ]中–离子。卤离子不会与PBu t(CN)2,PMe 2(CN)或PPh 2(CN)形成磷酰胺。

Cyanophenylphosphanes, Ph2PCN or PhP(CN)2, do not react with Me3SiCF3 or Me3SiC6F5 in the absence of cyanideions. Catalytic amounts of ionic cyanides such as [NEt4]CN, [18-crown-6-K]CN or NaCN initiate perfluoroorganylation reactions. The trifluoromethylphosphines, Ph2PCF3 and PhP(CF3)2, as well as the pentafluorophenylphosphines, Ph2PC6F5 and PhP(C6F5)2, are isolated in 60–75% yield. In dimethylformamide
在没有氰化物离子的情况下,氰基苯基膦Ph 2 PCN或PhP(CN)2不会与Me 3 SiCF 3或Me 3 SiC 6 F 5反应。催化量的离子型氰化物,例如[NEt 4 ] CN,[18-冠-6-K] CN或NaCN引发全氟有机化反应。三氟甲基膦Ph 2 PCF 3和PhP(CF 3)2以及五氟苯基膦Ph 2 PC 6 F 5和PhP(C 6 F 5)2被分离,产率为60-75%。在二甲基甲酰胺或丙酮溶液中,观察到副反应,而在CH 2 Cl 2和乙腈中的反应则选择性进行。我3 SICF 3除了二甲基甲酰胺和丙酮的羰基发生在治疗的Me 3 SICF 3种这些溶剂与催化量的氰化物,氰酸盐或即使在低温下硫氰酸盐的溶液。通过低温NMR研究证明在与过量的[18-冠-6-K] CN反应中反应性硅酸盐[Me 3 Si(CN)CF 3 ] -的形成。
