allylphosphanes has been developed using nBuLi-mediated hydrophosphination of conjugated dienes. In all the cases the phosphorus atom of the reacting phosphane attacked the sterically less demanding side of the diene exclusively. In addition, high regioselectivities towards 1,2- or 1,4-addition products were observed depending on the nature of the dienes. This hydrophosphination reaction was extended to a variety
已经使用 nBuLi 介导的共轭二烯氢膦化作用开发了高烯丙基和烯丙基膦的直接合成。在所有情况下,反应磷烷的磷原子专门攻击二烯的空间要求较低的一侧。此外,根据二烯的性质,观察到对 1,2- 或 1,4- 加成产物的高区域选择性。这种氢膦化反应扩展到各种底物,如苯乙烯衍生物、炔烃和 1,3,5-环庚三烯。X 射线衍射研究证实了三种氢膦化产物的结构。
