Reactions of alkyl and aryl sulfides with a monocarbon platinacarbaborane anion

The reaction of the monocarbon carbaborane complex Na[Pt(PEt3)2(η5-CB10H11)] with some diaryl- and dialkyl disulfides has been investigated. With Ph2S2, two new cage substituted products are formed, [Pt(SPh)(PEt3)(η5-9-SPh-7-CB10H10)] (1) and [Pt(SPh)(PEt3)(η5-8-SPh-11-SPh-7-CB10H9)] (2), whereas with View the MathML sourceBut2S2 the main product is the metal substituted complex, [Pt(SBut)(PEt3)(η5-7-CB10H11)] (4). All three new molecules have been identified spectroscopically (1H, 13C, 31P, 11B NMR) and through single crystal X-ray diffraction.
