    In solution, (THF)2U(BH4)4 and (HMPA)2U(BH4)4 adopt a trans-configuration, whereas (Ph3PO)2U(BH4)4 exists as an equilibrium mixture of two isomers. Thermolysis of (DME)U(BH4)4 gives the corresponding uranium (IV) hydride (DME)U(BH4)3H. Reaction of U(BH4)4 with TlCp or cyclopentadiene in toluene gives CpU(BH4)3.
    在溶液中,(THF)2 U(BH 4)4和(HMPA)2 U(BH 4)4采用反式构型,而(Ph 3 PO)2 U(BH 4)4以两种的平衡混合物形式存在异构体。热解(DME)U(BH的4)4给出了相应的铀(IV)氢化物(DME)U(BH 4)3 U(BH的H.反应4)4与TLCP或环戊二烯在甲苯中给出CPU(BH 4)3。

    The uranium(IV) triflate [U(OTf)4] (1) (OTf = OSO2CF3) gives stable adducts with Lewis bases, such as [U(OTf)4(py)] (2) (py = pyridine). The crystal structure of a solvate of [U(OTf)4(OPPh3)3] (3), which exhibits a bidentate OTf group, has been determined. Substitution of the triflate ligands of 1 with LiNEt2, Kacac (acac = MeCOCHCOMe), KCp (Cp = η-C5H5), and K2COT (COT = η-C8H8) has led to the formation
    三氟甲磺酸铀 (IV) [U(OTf)4] (1) (OTf = OSO2CF3) 与路易斯碱形成稳定的加合物,例如 [U(OTf)4(py)] (2) (py = 吡啶)。[U(OTf)4(OPPh3)3] (3) 溶剂化物的晶体结构已确定,该溶剂化物具有双齿 OTf 基团。用 LiNEt2、Kacac (acac = MeCOCHCOMe)、KCp (Cp = η-C5H5) 和 K2COT (COT = η-C8H8) 取代 1 的三氟甲磺酸酯配体导致 [U(NEt2)4]、[ U(acac)4]、[U(Cp)3(OTf)] (4) 和 [U(COT)(OTf)2(py)] (5) 分别。然而,双(环戊二烯基)化合物 [U(Cp*)2(OTf)2] (6) (Cp* = η-C5Me5) 和 [U(Cp)2(OTf)2(py)] (7) 可以不能从 1 制备。 配合物 4-7 已经从

  • Observations on the thermal decomposition of some uranium(IV) tetraalkyls

    The thermally unstable products of the reactions 4 RLi + UCl4 (R = various alkyl groups), presumed to be uranium tetraalkyls, decompose readily at room temperature in ethereal or hydrocarbon solvents. When R contains a β-hydrogen, comparable quantities of alkane (RH) and alkene (RH-H2) are produced along with trace amounts of the dimer, RR. This result indicates that uranium alkyl compounds readily
    推测为四烷基铀的反应4 RLi + UCl 4(R =各种烷基)的热不稳定产物在室温下在乙醚或烃类溶剂中容易分解。当R含有β氢,烷烃的可比量(RH)和烯烃(RHH 2)与二聚体,RR痕量一起产生。该结果表明,在适当的情况下(配位不饱和),铀烷基化合物容易通过β-氢消除而分解。当不存在β-氢时,烷烃RH是主要产物。立体化学保留在2-顺式和2-反式-2-丁烯基化合物的α-碳原子上,表明2-丁烯不是由游离R形成的-部首。

    In contrast to some earlier indications, various organo-uranium(IV) complexes of the general type Cp3UX (Cp = η5-C5H5; X = CH3, C2H5, i-C3H7, n-C4H9, t-C4H9, N(C2H5)2, and even P(C6H5)2 and NCBH3, but not BH4 or NCS) react in solution with CO under mild conditions, (viz. room temperature and atmospheric pressure of CO). The (IR, 1H NMR and NIR/VIS) spectroscopic properties of the (1:1) insertion products
