and 2-diethylamino derivatives of 1,3-bis(trimethylsilyl)-1,3,2-diazaphospha-[3]ferrocenophane were prepared, and the molecular structure of the latter was determined by X-ray diffraction. The phosphines could be oxidized by their slow reactions with sulfur or selenium, and the molecular structures of three sulfides and one selenide were determined. In contrast, the synthesis of oxides was less straightforward
制备了1,3-双(三甲基甲硅烷基)-1,3,2-二氮杂磷-[3]二茂铁的2-叔丁基、2-苯氧基和2-二乙氨基衍生物,并确定了后者的分子结构通过 X 射线衍射。膦可以通过与硫或硒的缓慢反应而被氧化,并确定了三种硫化物和一种硒化物的分子结构。相比之下,氧化物的合成就不那么简单了。通过多核磁共振方法(一维和二维 1H、13C、15N、29Si、31P 和 77Se 核磁共振波谱)对溶液中的所有新化合物进行了表征。
