Treatment of diphosphines Ph2P(CH2)nPPh2 (n = 1, 2, 4, 6) and [Fe(η5-C5H4PR′2)2] (R′ = Ph, iPr) with a two-fold excess of (RO)2P(S)N3 (R = Et, Ph) results in the high-yield formation of the N-thiophosphorylated bis(iminophosphorane) derivatives (CH2)n[PNP(S)(OR)2}Ph2]2 and Fe(η5-C5H4[PNP(S)(OR)2}R′2])2, respectively. The reactions of these ligands with AgSbF6 in a 1 : 1 molar ratio have been investigated. The resulting silver(I) complexes, derived from the selective coordination of the PS units, have been characterized by IR, NMR and MS (FAB) spectroscopy and, in selected cases, by X-ray crystallography. Monomeric, dimeric and polymeric solid-state structures, depending on the nature of the ligand backbone, have been found.
用两倍过量的 (RO)2P 处理二膦 Ph2P(CH2)nPPh2 (n = 1, 2, 4, 6) 和 [Fe(η5-C5H4PR′2)2] (R′ = Ph, iPr) (S)N3 (R = Et, Ph) 导致 N-硫代磷酸化双(亚氨基正膦) 衍生物 (CH2)n[PNP(S)(OR)2}Ph2]2 和 Fe(分别为 η5-C5H4[PNP(S)(OR)2}R′2])2。已经研究了这些配体与 AgSbF6 以 1:1 摩尔比的反应。所得的银(I)络合物源自 PS 单元的选择性配位,已通过 IR、NMR 和 MS (FAB) 光谱进行了表征,在某些情况下还通过 X 射线晶体学进行了表征。已发现单体、二聚和聚合固态结构,具体取决于配体主链的性质。
