This study focuses on synthesis and investigation of coordination modes of phosphorus and sulfur-containing C-stereogenic compounds, prepared from thioanisole. Isolation of the C-stereogenic organolithium compound [RR'CHLi2THF] (R = CHS, R’ = (CH)Si, THF = tetrahydrofuran) instead of usage turned out to be mandatory for controlled reactivity. Variation of the steric and electronic properties of the substituents at phosphorus furnished three different phosphane substituted P, S ligands RR'CHPPh, RR'CHP(N(CH)) and RR'CHP(CH). Furthermore, the corresponding chalcogenphosphoranes were synthesized by oxidation with elemental sulfur and selenium. Preliminary investigation of the coordination behavior of RR'CHP(CH), RR'CHP(S)(CH) and RR'CHP(Se)(CH) towards coinage metals was explored with Au(tht)Cl, both for the phosphanes and the corresponding phosphoranes. Intermolecular aurophilic interactions have been observed for the selenophosphorane exclusively.

一组 C-立体异构 P、S 配体的合成、结构和稳定性

本研究的重点是从茴香硫醚制备的含磷和硫的C-立体化合物的配位模式的合成和研究。事实证明，为了控制反应性，必须分离 C-立体有机锂化合物 [RR'CHLi2THF]（R = CHS，R' = (CH)Si，THF = 四氢呋喃）而不是使用。磷上取代基的空间和电子性质的变化提供了三种不同的膦取代的P、S配体RR'CHPPh、RR'CHP(N(CH))和RR'CHP(CH)。此外，通过用元素硫和硒氧化合成了相应的硫属正膦。使用 Au(tht)Cl 初步研究了 RR'CHP(CH)、RR'CHP(S)(CH) 和 RR'CHP(Se)(CH) 对造币金属的配位行为，无论是磷烷还是磷烷。相应的正膦。仅在硒代正膦中观察到了分子间亲金相互作用。
