2,4-Diferrocenyl-1,3-dithiadiphosphetane 2,4-disulfide; structure and reactions with catechols and [PtCl2(PR3)2](R = Et or Bun)

Abstract

Reaction of ferrocene (or 1,1′-dimethylferrocene) with P₄S₁₀ yielded R′P(S)S₂P(S)R′(R′= ferrocenyl)(or the analogous dimethylferrocene species). This compound reacted with catechols to form R′P(S)O₂C₂ ring systems and with [PtCl₂(PR₃)₂](R = Et or Buⁿ) to give [R′PS₃Pt(PR₃)₂]. The new compounds have been characterised spectroscopically with illustrative examples having been fully studied by X-ray crystallography.
