  • A Convenient Synthetic Protocol to 1,2-Bis(dialkylphosphino)ethanes
    作者:Laurence R. Doyle、Alex Heath、Choon Heng Low、Andrew E. Ashley

    1,2-Bis(dialkylphosphino)ethanes are readily prepared from the parent phosphine oxides, via a novel sodium aluminium hydride/sodium hydride reduction protocol of intermediate chlorophosphonium chlorides. This approach is amenable to multi-gram syntheses, utilises readily available and inexpensive reagents, and benefits from a facile non-aqueous work-up in the final reductive step.

    The synthesis of nickel(0) complexes usually requires the employment of strong reducing agents, including powerful hydride donors such as LiHBEt3, LiAlH4, and DIBAL-H. Herein, we have reduced the Ni(II) complex [(dippe)NiCl2] (1a) at room temperature by using KOH in aqueous media to yield the low-valent complex [Ni(dippe)2] (4a) as the main product, along with the formation of dippeO2. In order to
    镍(0)配合物的合成通常需要使用强还原剂,包括强力氢化物供体,例如LiHBEt 3,LiAlH 4和DIBAL-H。在此,我们通过在水性介质中使用KOH在室温下还原了Ni(II)络合物[(dippe)NiCl 2 ](1a),以低价络合物[Ni(dippe)2 ](4a)为主要成分产物,并形成dippeO 2。为了深入了解反应机理,分离了一系列中间体,并在不同的反应阶段进行了表征。结果,Ni(II)羟基桥(2b)和氢化物(3b))复合物被确定为关键中间体。此外,还研究了在镍介导的过程中使用水作为氢源并将其成功应用于选定的有机底物的加氢脱氟,加氢脱硫和加氢。
  • Nickel-Catalyzed Reductive Hydroesterification of Styrenes Using CO<sub>2</sub> and MeOH

    Complexes [(dippe)Ni(mu-H)](2) (A) (dippe = 1,2-bis-di-isopropylphosphino)ethane) and [(dtbpe)Ni(mu-H)](2) (B) (dtbpe = 1,2-bis-di-tert-butylphospino)ethane) catalyze the reductive hydroesterification of styrenes with the use of CO2 and MeOH. The latter acts as a hydrogen source and as an esterificating agent, to yield the corresponding branched and linear esters in moderate to good yields. In all of the studied reactions the linear esters were obtained in higher amounts than the branched ones. When the hydroesterification reaction was carried out using a stoichiometric metal/substrate ratio, the complexes [(P-P)Ni(CO)(2)] and [(P-P)Ni(CO3)] (P-P = dippe or dtbpe) were isolated and characterized by standard spectroscopic methods. Compounds [(dtbpe)Ni(CO)(2)] and [(dtbpe)Ni(CO3)] were also fully characterized by single-crystal X-ray diffraction.

    the bisphosphinites R2POCH2CH2OPR2 (R=Ph, iPr and Cy) at 190–260 °C for 24 h gave the bisphosphine oxides, R2P(O)CH2CH2(O)PR2 in 9% (Ph), 90% (iPr) and 93% (Cy) yields. A DSC study of the thermal rearrangement of Cy2POCH2CH2OPCy2 to Cy2P(O)CH2CH2(O)PCy2 yielded an enthalpy of isomerization of −40.4±0.6 kcal mol−1.

    The reaction of [(dippe)Ni(μ-H)]2 (A) (dippe = 1,2-bis(diisopropyl-phosphinoethane) with CO2 in toluene afforded the carbonyl nickel(0) compounds of the type (dippe)Ni(CO)]2(μ-dippe)}(1) and (dippe)Ni(CO)(dippeO)] (2), which were characterized by standard spectroscopic methods; complex (1) was also characterized by single crystal X-ray diffraction. Reaction of (A) with SO2 yields the thiosulfate nickel(II) compound [Ni(dippe)(S2O3)] (5), which was fully characterized by standard spectroscopic methods and X-ray crystallography. In both cases, a reduction reaction of CO2 to CO and SO2 to S2O32− with (A) took place under mild conditions.
