如循环伏安法和ESR光谱所揭示的,苄基三乙基氯五羰基钼酸铵(1)和氯五羰基钨酸盐(2)配合物通过氯化物交换和氧化还原过程与DME中的CF 3 SO 3 Ag反应。所得的中间体M(I)物种与M(0)和M(II)不成比例,因此需要3当量的TfOAg才能定量转化为M(II)配合物。类似的PPN配合物3和4仅经历氧化还原过程(在DME中)。在这种情况下,可能是由于络合阴离子与抗衡离子之间的强配对而排除了氯离子的交换。

In order to facilitate studies of the synthesis and reactivity of pentafluorophenylmolybdenum(0) carbonyl complexes, an efficient synthetic route to the pentacarbonyl complex, [Mo(C(6)F(5))(CO)(5)](-), has been sought. It has now been shown that the known organometallic compounds AgC(6)F(5) and PPN[MoCl(CO)(5)] [PPN = bis(triphenylphosphoranylidene)ammonium] react to give PPN[Mo(C(6)F(5))(CO)(5)] in high purity and good yield. This compound has been characterized by IR, NMR, elemental analysis, and X-ray crystallography. (C) 2000 Elsevier Science S.A. All rights reserved.
