Abstract

Title full: Sterically-induced low temperatur polyhedral rearrangements of carbaplatinaboranes: Synthesis and crystal structures of 1-Ph-3,3-(PMe₂Ph)₂-3,1,2-PtC₂B₉H₁₀, 1-Ph-3,3-(PMe₂Ph)₂-3,1,11-PtC₂B₉H₁₀, 11-Ph-3,3-(PMe₂Ph)₂-3,1,11-PtC₂B₉H₁₀ and 1,11-Ph₂-3,3-(PMe₂Ph)₂-3,1,11-PtC₂B₉H₉. 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°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-C₂B₉H ₉] 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.
