Abstract

The facile reaction of [CpCr(CO)₃]₂ with one mole equivalent of bis(diphenylthiophosphinyl)disulfane, Ph₂P(S)SSP(S)PPh₂ led to the isolation of dark purplish brown solids of CpCr(CO)₂(S₂PPh₂) (2) and blue solids of CpCr(S₂PPh₂)₂ (3) in 50 and 10% yields, respectively. Proton NMR spectral studies demonstrated that 3 is derived from 2, the primary product. IR spectral data indicated that 2 possesses cis CO ligands and a bidentate SP(S)Ph₂ ligand, whilst 3 contains both a unidentate and a bidentate ligand, as confirmed by its X-ray diffraction analysis. Variable temperature ¹H and ³¹P spectral studies showed the occurrence of very rapid unidentate-bidentate exchange between the ligands in 3 in the temperature range -80-60°C.
