The reaction of [CpMo(CO)3]2 (1) and its congener, the triply bonded [CpMo(CO)2]2 (2) with 2,4-bis(p-tolylthio)1,3-dithia-2,4-diphosphetane-2,4-disulfide (DR, Davy’s reagent) in toluene at 110 and 70 °C, respectively, led to the isolation of dark brown solids of CpMo(CO)2(S2P(SPhMe)2) (3), deep pink solids of Cp2Mo2(CO)5(S2P(SPhMe)) (4) and dark purple solids of Cp2Mo2(μ-S)(μ-S2)(μ-SPhMe) (5) with yields dependent on reaction conditions. Thermolytic studies followed by 1H NMR indicated that 3 and 4 had degraded to 5. The postulated mechanism involves P–S bond cleavage in DR leading to a ring opening and desulfurization process.

The synthetic pathway postulated in this study indicates that DR had undergone P–S bond cleavage leading to ring opening and desulfurization process.Figure optionsDownload as PowerPoint slide
