cyclo-P 3complexes [(triphos]M(η 3 -P 3 )]-[triphos = 1,1,1-tris(diphenylphosphanylmethyl)ethane; M = Co (1), Rh (2)] with stoichiometric amounts of [CpRu-(CH3 CN) 2 (PR 3 )]PF 6 [R = Ph (3), Me (4), Cy (5)] in CH2Cl2 in the presence of CH3 CN yields the bimetallic adducts [((triphos)M}(μ,η 3 : 1 -P3)(CpRu(CH3CN)(PR3)}]PF 6 [M = Co; R = Ph (6), Me (7), Cy (8); M = Rh; R = Ph, (9), Me (10), Cy
所有化合物均已通过元素分析和在溶液中通过 3 1 P 和 1 H NMR 光谱进行表征。11 和 14 不同温度下的 3 1 P 1 H} EXSY NMR 光谱数据突出显示了交换三磷和环-P 3 磷核的独立动态过程的发生。对 6 进行的 X 射线结构研究证实了 μ,n 3 : 1 - 环-P 3 配体的连接行为的发生。
