The acceptor properties of the alkylchlorophosphoranes PRnCl5–n(R = Me, n= 1 or 2; R = Et, n= 1—3), and of their derivatives with suitable Lewis acids (SbCl5 or PCl5), towards the Lewis bases Cl–, pyridine, 2,2′-bipyridine, and 1,10-phenanthroline have been investigated, using mainly 31P n.m.r. spectroscopy. Complex formation was found to occur with PMeCl4, PEtCl4, and their derivatives, but the di-
烷基氯膦酸酯PR n Cl 5– n(R = Me,n = 1或2; R = Et,n = 1-3)以及它们的衍生物与合适的路易斯酸(SbCl 5或PCl 5)的受体性质,主要使用31 P nmr光谱研究了对路易斯碱Cl –,吡啶,2,2'-联吡啶和1,10-菲咯啉的反应。发现与PMeCl 4,PEtCl 4形成络合物,以及它们的衍生物,但是二烷基和三烷基氯膦不显示出受体能力的证据。已分离出几种新化合物,并通过元素分析和(在某些情况下)红外光谱进一步表征。
