在本文中，描述了使用[β-（叔丁氧基）二硅烷基]锂3合成（叔丁氧基）低聚硅烷。化合物3通过（a）用锂还原（叔丁氧基）氯二苯基硅烷（1）和（B）用n-BuLi进行[（叔丁氧基）二苯基甲硅烷基]锡烷6的锡-锂交换来制备。二硅烷基锂3与单卤代硅烷和二卤代硅烷以及二卤代二硅烷反应以形成在末端硅原子处带有叔丁氧基基团的三硅烷、五硅烷和六硅烷。还进行了低聚硅烷的官能团转化。使用核磁共振光谱、紫外可见光谱、质谱和X射线晶体学对低聚硅烷的结构进行表征。通过密度泛函理论计算讨论了其结构和物理性质。
Herein, the synthesis of (tert‐butoxy)oligosilanes using [β‐(tert‐butoxy)disilanyl]lithium3is described. Compound3was prepared by (a) the reduction of (tert‐butoxy)chlorodiphenylsilane (1) with lithium and (b) tin‐lithium exchange of [(tert‐butoxy)diphenylsilyl]stannane6withn‐BuLi. Disilanyllithium3was reacted with mono‐ and dihalosilanes and a dihalodisilane to form tri‐, penta‐, and hexasilanes bearingtert‐butoxy groups at the terminal silicon atoms. Functional group transformations of the oligosilanes were also performed. The structures of the oligosilanes were characterized using nuclear magnetic resonance spectroscopy, ultraviolet‐visible spectroscopy, mass spectrometry, and X‐ray crystallography. The structures and photophysical properties were discussed based on density functional theory calculations.
