First amino bis(picolyl) and amino bis(quinaldinyl) phosphines were synthesized by reaction of the corresponding amino dichlorophosphines – the new carbazolyl dichlorophosphine (1) and diisopropylamino dichlorophosphine (2) with either picolylTMS (6), quinaldinylTMS (15) or their respective lithium derivatives 12 and 16. The deviation of the standard synthesis via the silyl route is necessary for the synthesis of the diisopropylamino derivatives 11 and 14 due to the fact that compound 2 is not reacting with 6 or 15 even at reflux conditions. All new compounds are extensively characterized by multinuclear NMR spectroscopy and some also by single crystal X-ray diffraction. Also the molecular and crystal structure of the new dichlorophosphine 1 was determined.

氨基双（picolyl）和氨基双（quinaldinyl）膦的首个代表的合成

通过相应的氨基二氯膦–新的咔唑基二氯膦（1）和二异丙基氨基二氯膦（2）与picolylTMS（6），quinaldinylTMS（15）或它们各自的反应，合成了第一个氨基双（吡啶甲基）和氨基双（喹啉基）膦锂衍生物12和16。由于二化合物即使在回流条件下也不与6或15反应，因此通过甲硅烷基途径的标准合成偏差对于二异丙基氨基衍生物11和14的合成是必要的。所有新化合物都通过多核NMR光谱进行了广泛表征，有些还通过单晶X射线衍射进行了表征。还确定了新的二氯膦1的分子和晶体结构。
