摘要：

Reaction of cis-Pt(PMe2Ph)2Cl2 with Tl2[7-Ph-7,8-nido-C2B9H10] affords 1-Ph-3,3-(PMe2Ph)2-3,1,2-PtC2B9H10, mild thermolysis (55-degrees-C) of which yields 1-Ph-3,3-(PMe2Ph)2-3,1,11-PtC2B9H10 and 11-Ph-3,3-(PMe2Ph)2-3,1,11-PtC2B9H10. Both of the latter compounds are produced by the microwave irradiation of a mixture of cis-Pt(PMe2Ph)2Cl2 and [HNMe3][7-Ph-7,8-nido-C2B9H11]. When cis-Pt(PMe2Ph)2Cl2 is allowed to react with Tl2[7,8-Ph2-7,8-nido-C2B9H9] at room temperature the only isolable species is 1,11-Ph2-3,3-(PMe2Ph)2-3,1,11-PtC2B9H9. The generation of rearranged products with 3,1,11-PtC2B9 architectures is inconsistent with a diamond-square-diamond mechanism for the isomerisation of icosahedral heteroboranes.
