at phosphorus was dependent on the ligand used. For example, when a stoichiometric reaction between PCl3 and thiophene-3,4 diyldimethaneamine (R = Mes) was carried out, the synthesis of a bis-substituted diphosphino- product was isolated. If the R = Dipp ligand derivative was employed, both a 2:1 and 1:1 stoichiometric reaction between PCl3 and the diamine was observed. Nevertheless, the cyclic di
已经合成了一种在主链中含有简单噻吩环的新型二胺配体。通过相应的苯胺和 3,4-二甲酰基噻吩之间的缩合反应,在氮原子上被 2,4,6-三甲基苯基 (Mes) 或 2,6-二异丙基苯基 (Dipp) 取代,得到两种不同的配体衍生物。在以后针对环状二氨基氯膦的化学中,磷的取代取决于所使用的配体。例如,当进行 PCl3 和噻吩-3,4 二基二甲胺 (R = Mes) 之间的化学计量反应时,分离出双取代二膦基产物的合成。如果使用 R = Dipp 配体衍生物,PCl3 和二胺之间会发生 2:1 和 1:1 的化学计量反应。然而,环状二氨基氯膦(即
