Pentacoordinate 1,2-thiaphosphetenes bearing the Martin ligand were synthesized by the reaction of the corresponding phosphorus ylide with isothiocyanates. Their mass and NMR spectral data showed that they have 1:2 adducts of the phosphorus ylide and isothiocyanates, which have a distorted trigonal bipyramid with oxygen and sulfur atoms at the apical positions. Thermolysis of the phenyl isothiocyanate
通过相应的磷叶立德与异硫氰酸酯的反应合成了带有 Martin 配体的五配位 1,2-硫代膦烯。他们的质量和核磁共振光谱数据表明,他们有 1:2 的叶立德和异硫氰酸酯的加合物,它们有一个扭曲的三角双锥,在顶端位置有氧和硫原子。苯基异硫氰酸酯加合物的热解得到相应的环状硫代次膦酸酯,为含磷产物,产率几乎是定量的。

The phosphonium cations bearing the Martin ligand abstracted a fluoride ion from their counter anion, tetrafluoroborate, and the corresponding fluorophosphoranes were obtained in good yields.
