  Synthesis and characterisation of {Mo(η-L)(CO)3}+ (η-L = C5H5 or C5Me5) fragments ligated with [CB11H12]− and derivatives. Isolation and structural characterisation of an intermediate in a silver salt metathesis reaction

  摘要：

  The synthesis of {Mo(η-L)(CO)3}+ (η-L = C5H5 or C5Me5) fragments, ligated to the mono-anionic, weakly co-ordinating, carboranes [closo-1-CB11H12]− and [closo-CB11Br6H6]−, has been investigated. Treatment of [MoCp(CO)3X] (X = Cl or I) with Ag[CB11H12] eventually affords the zwitterionic complex [MoCp(CO)3(x-μ-H-1-CB11H12)] (x = 12 or 7), via an intermediate dimeric species [MoCp(CO)3X·Ag(CB11H12)]2. For X = I this intermediate has been characterised by 1H, 11B NMR spectroscopy and X-ray crystallography and represents the first structurally characterised intermediate in a silver salt metathesis reaction. When the less nucleophilic carborane [CB11Br6H6]− (as its silver salt) is used metathesis is halted at the intermediate stage, affording the complex [MoCp(CO)3I·Ag(CB11Br6H6)]2. Silver salt metathesis does not proceed using the sterically more demanding [Mo(Cp*)(CO)3I], with only intractable products isolated. The carborane anion can be introduced into the co-ordination sphere of this complex by reaction of [H(OEt2)x][CB11H12] with [Mo(Cp*)(CO)3Me] affording [Mo(Cp*)(CO)3(x-μ-H-1-CB11H12)] (x = 12 or 7). All new compounds have been characterised by multinuclear NMR spectroscopy and X-ray crystallography.

  摘要：

  从 [Cp(CO)3MoI] 中提取碘化物 （CP = η5-C5H5) 使用弱配位阴离子 [closo-CB11H11Br]· 的银盐，最初提供中间二聚复合物 [MoCp(CO)3I·Ag(CB11H11Br)]2，其具有中心 { AgI}2 核心附有两个固态碳硼烷阴离子。长时间的反应确实会导致 AgI 消除，形成 [MoCp(CO)3(CB11H11Br)]，但不完全。使用新的三苯甲基盐 [CPh3][closo-CB11H11Br] 从 [Cp(CO)3MoH] 中提取氢化物，可以以良好的产率分离出该配合物。类似地，该氢化物源与 CD2Cl2 中的 [CPh3][closo-CB11H6Br6] 反应导致氢化物提取，但形成了产物混合物，表明由氢化物桥联二聚体 [{Cp(CO)3Mo}2( μ-H)][closo-CB11H6Br6]，阴离子配位络合物[Cp(CO)3Mo(closo-CB11H6Br6)]和溶剂加合物[Cp(CO)3Mo(ClCD2Cl)][closo-CB11H6Br6]。 Ag[closo-HCB11Me11] 与 [Cp(CO)3MoX] 的反应 (X = Cl, I) 产生具有 [Cp(CO)3MoX]6Ag2 中心核心（X = I 的晶体学特征）的中间复合物，与全甲基化碳硼烷阴离子没有相互作用。长时间的反应确实会导致部分 AgX 消除，形成卤化物桥联二聚体 [{CpMo(CO)3}2(μ-X)][closo-HCB11Me11]。使用新的三苯甲基盐 [CPh3][closo-HCB11Me11] 从 [Cp(CO)3MoH] 中提取氢化物导致氢化物桥联二聚体 [{Cp(CO)3Mo}2(μ-H)][ 的干净形成closeso-HCB11Me11]。已将两种阴离子 [closo-CB11H6Br6]‐ 和 [closo-HCB11Me11]‐ 与 [B(ArF‐²)4]‐ 进行了比较 [ArFâ² = 3,5-双(三氟甲基)苯基]，使用 [Cp(CO)2(PPh3)Mo]+ 催化剂进行 3-戊酮的布洛克离子氢化。全甲基化阴离子的催化性能略优于其六溴化同系物，但仍比 [B(ArF‐)4]‐ 慢。
