The reaction of molybdenum complexes with a tris(pyrazolyl)borate ligand (EtN[TpMo(CO)] and EtN[TpMo(CO)] (Tp = hydridotris(pyrazolyl)borate, Tp = hydridotris(3,5-dimethylpyrazolyl)borate)) and InBr at a 1:1 molar ratio afforded molybdenum-indane complexes (EtN[TpMo(CO)(InBr)] and EtN[TpMo(CO)(InBr)] ). In addition, tungsten-indane complexes, EtN[TpW(CO)(InBr)] and EtN[TpW(CO)(InBr)] , were obtained by the reaction of corresponding tungsten complexes. Complex reacted with HO to form the hydrido complex TpW(CO)H, in which the W-In bond was cleaved. On the other hand, reacted with three equiv. of AgNO to form EtN[TpW(CO){In(ONO)}] , in which three substituents on the In were exchanged while retaining the W-In dative bond. Complexes - were fully characterized using NMR measurements and elemental analyses, and the structures of - and EtN[Tp*W(CO)] were determined via X-ray crystallography. These are the first examples of mononuclear molybdenum- and tungsten-indane complexes with Mo-In and W-In dative bonds.
钼配合物与三（吡唑基）硼酸酯配体（EtN[TpMo(CO)]和EtN[TpMo(CO)]（Tp = 氢化三（吡唑基）硼酸酯，Tp = 氢化三（3,5-二甲基吡唑基）硼酸酯））以及InBr以1:1的摩尔比反应，得到钼茚满配合物（EtN[TpMo(CO)(InBr)]和EtN[TpMo(CO)(InBr)]）。此外，通过相应钨配合物的反应得到了钨茚满配合物EtN[TpW(CO)(InBr)]和EtN[TpW(CO)(InBr)]。配合物与HO反应形成氢化物配合物TpW(CO)H，其中W-In键被切断。另一方面，与三当量的AgNO反应形成EtN[TpW(CO){In(ONO)}]，其中In上的三个取代基发生了交换，同时保留了W-In配位键。使用NMR测量和元素分析对配合物 - 进行了全面表征，并通过X射线晶体学确定了 - 和EtN[Tp*W(CO)]的结构。这些是具有Mo-In和W-In配位键的单核钼和钨茚满配合物的首个实例。
