The phenylthio group was introduced to the sterically protected phosphaethene-system and 1-(phenylthio)-2-(2,4,6-tri-t-butylphenyl)-2-phosphaethenyllithium was generated. It has been shown that the lithium reagent behaves like a halo-derivative, in terms of elimination, metalation, and coupling reaction, while the E/Z isomerization was observed for the phenylthio-derivative, and a 1,4-diphospha-1,3-butadiene
苯硫基被引入到空间保护的磷酰胺体系中,并生成 1-(苯硫基)-2-(2,4,6-三叔丁基苯基)-2-磷酰胺基锂。已经表明,锂试剂在消除、金属化和偶联反应方面表现得像卤代衍生物,而苯硫代衍生物和 1,4-diphospha-1 则观察到 E/Z 异构化, 3-丁二烯作为氧化偶合产物通过X-射线分析。
