  • Nickel-Catalyzed Reductive Hydroesterification of Styrenes Using CO<sub>2</sub> and MeOH
    作者:Lucero González-Sebastián、Marcos Flores-Alamo、Juventino J. García
    DOI:10.1021/om300819d
    日期:2012.12.10
    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.
  • A Convenient Synthetic Protocol to 1,2-Bis(dialkylphosphino)ethanes
    作者:Laurence R. Doyle、Alex Heath、Choon Heng Low、Andrew E. Ashley
    DOI:10.1002/adsc.201300787
    日期:2014.2.10
    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.
    通过中间体氯代氯化phosph的新型氢化铝铝/氢化钠还原方案,可以容易地由母体氧化膦制备1,2-双(二烷基膦基)乙烷。该方法适用于多克合成,使用容易获得且便宜的试剂,并且在最终的还原步骤中得益于简便的非水后处理。
