Abstract (β-Chloroethylphosphinidene)pentacarbonyltungsten, generated from the appropriate 7-phosphanorbornadiene precursor, reacts with aniline to give [(β-chloroethyl)(phenylamino)phosphane]pentacarbonyltungsten, which cyclizes upon phosphorus-metallation with n-butyllithium. (1-Phenylaminophosphirane)pentacarbonyltungsten, thus obtained, reacts with dry HCl to give the title compound as a stable
摘要由适当的7-磷杂降冰片二烯前驱体生成的(β-氯乙基次膦)五羰基钨与苯胺反应生成[(β-氯乙基)(苯基氨基)膦]五羰基钨,该磷在与正丁基锂进行磷金属化反应后环化。如此获得的(1-苯氨基膦烷)五羰基钨与干燥的HCl反应,得到标题化合物,为稳定的结晶固体,已在结构上表征。与母体膦烷相比,(1-氯膦烷)五羰基钨显示出更短的P(C键(1.78–1.81对1.867 A)和更大的CPC环内角(49.2对47.4°),这说明了配合物的稳定性增强。用EtO-(EtOT1),O2-(H2O + DBO),(EtO)2P(O)-和H-(LiAlH4)可以观察到PCl键上的正常亲核取代。
