The reactions of thallium salt Tl[7-SMe2-7,8-C2B9H10] with [(cod)RhCl]2 and [Cp*RuCl]4 are accompanied by room-temperature polyhedral rearrangement, giving rhoda- and ruthenacarboranes 1-cod-8-SMe2-1,2,8-RhC2B9H10 (2) and 1-Cp*-8-SMe2-1,2,8-RuC2B9H10 (3), respectively. According to DFT calculations, the rearrangement could be attributed to the triangular face rotation mechanism. The reaction of iridium
salt盐Tl [7-SMe 2 -7,8-C 2 B 9 H 10 ]与[(cod)RhCl] 2和[Cp * RuCl] 4的反应伴随有室温多面体重排,得到rhoda-和钌碳硼烷1-cod-8-SMe 2 -1,2,8-RhC 2 B 9 H 10(2)和1-Cp * -8-SMe 2 -1,2,8-RuC 2 B 9 H 10(3)。根据DFT计算,重排可以归因于三角形面旋转机制。铱衍生物1-cod-8-SMe的反应2 -1,2,8-IRC 2乙9 ħ 10(1)用无水氢卤酸HX(X =氯,溴,I)导致二聚体卤化物iridacarboranes [1,1-X 2 -8-SME 2 - 1,2,8-IrC 2 B 9 H 10 ] 2 [ 4a – c ; X = Cl(a),Br(b),I(c)]。溴化物4B与铊[铊(η-7,8--C发生反应2乙9 ħ 11)]和TLCP给予iridacarboranes
