Abstract

A new lithium salt of diphosphane, (iPr2N)PhP–P(SiMe3)Li (2), featuring two substituents with distinct electronic characterstics, is reported. A subsequent reaction of the compound 2 with benzophenone was yielded a novel phosphanylphosphaalkene (3). The isolated compound was subsequently treated with nBuLi and PhLi to obtain stable activators (3a and 3b) for the potential polymerization of phosphorus-rich compounds.

取代基对磷酰磷烯烃P-P键和P=C键性质的影响
提出了一种新的二膦锂盐(iPr₂N)PhP-P(SiMe₃)Li(2),具有两个电子分化的取代基。然后将其与二苯甲酮反应,得到一种新型的磷酰磷烯(3)。分离的化合物随后用nBuLi和PhLi处理,得到稳定的活化剂(3a和3b),用于富磷化合物的潜在聚合。
