elemental analysis and (in some cases) i.r. spectroscopy. These ions apart from [P(C6F5)2(CN)Y]–} represent the first simple phosphoranides with an organo-group attached to phosphorus and no cyano-groups present. The species with two pentafluorophenyl groups are the first phosphoranides with two organo-groups directly bound to phosphorus. No acceptor properties towards halide ions were shown by P(CCl3)Cl2
[P(C 6 F 5)X 2 Y] –(X = Cl,Y = Cl,Br或I; X = Br,Y = Br或I; X = NCS, Y = Cl,Br,I或NCS)或[P(C 6 F 5)2 X(Y)] –(X = Cl,Y = Cl,Br或I; X = Br,Y = Br或I ; X = CN,Y = Cl,Br,I或NCS)已通过31 P nmr光谱法在溶液中鉴定。大多数物种已分离为与四烷基铵离子的盐,并通过元素分析和(在某些情况下)红外光谱进一步表征。这些离子除[P(C 6 F 5)2(CN)Y] – }代表第一个简单的磷酰胺,其有机基团与磷相连,并且不存在氰基。具有两个五氟苯基的物质是具有两个直接键合于磷的有机基团的第一磷酰胺。P(CCl 3)Cl 2或P(C 6 F 5)2(NCS)没有显示出对卤离子的受体性质。
