ScholarBank@NUS Repository. https://doi.org/10.1016/j.ica.2009.10.013 | Abstract: | Reaction of [Pt2(μ-S)2(PPh3)4] with a number of transition metal-iodo complexes leads to the formation of the cationic iodo analogue [Pt2(μ-S)(μ-I)(PPh3)4]+, identified using electrospray ionisation mass spectrometry (ESI MS). Synthetic routes to this complex were developed, using the reaction of [Pt2(μ-S)2(PPh3)4] with either [PtI2(PPh3)2] or elemental iodine. The complex was characterised by NMR spectroscopy, ESI MS and an X-ray structure determination, which reveals the presence of a planar, disordered {Pt2SI}+ core. Monitoring the iodine reaction by ESI MS allows the identification of various iodine species, including the short-lived intermediate [Pt2(μ-S)2(PPh3)4I]+, which allows a mechanism for the reaction to be proposed. © 2009 Elsevier B.V.
