    摘要:
    已开发出一种新颖的将叔膦氧化物氧化为相应膦的选择性催化还原方法。值得注意的是,即使在低温(70°C)下,催化剂负载量为1-5 mol%时,反应仍可顺利进行。在优化的条件下,可以选择性还原各种氧化膦,通常以高于90%的高收率获得所需的膦。此外,我们已经开发了一种一锅法反应程序,用于制备有价值的膦-硼烷加合物。在还原步骤之后,简单地添加BH 3· THF,就可以得到所需的加合物,产率高达99%。

  • The Trityl‐Cation Mediated Phosphine Oxides Reduction
    作者:Claire Laye、Jonathan Lusseau、Frédéric Robert、Yannick Landais
    DOI:10.1002/adsc.202100189
    日期:2021.6.21
    Reduction of phosphine oxides into the corresponding phosphines using PhSiH3 as a reducing agent and Ph3C+[B(C6F5)4]− as an initiator is described. The process is highly efficient, reducing a broad range of secondary and tertiary alkyl and arylphosphines, bearing various functional groups in generally good yields. The reaction is believed to proceed through the generation of a silyl cation, which reaction

    Boron co-ordination compounds of the type L,BH3(L = Me3N, Et3N, Py, and Et3P) and Me3N,BH2X (X = Cl, Br, and I) are shown to form hydrogen-bonded complexes with OH (MeOH, PhOH, and p-F·C6H4·OH) in carbon tetrachloride solution. These complexes appear to be formed via OH ⋯ BH3 and OH ⋯ BH2 interactions and are readily detected by the appearance of a low-frequency i.r. OH stretch. Formation of similar

  • Selective Hydrogenation of Amides to Amines and Alcohols Catalyzed by Improved Iron Pincer Complexes
    作者:Felix Schneck、Maik Assmann、Markus Balmer、Klaus Harms、Robert Langer
    DOI:10.1021/acs.organomet.6b00251
    日期:2016.6.13
    A comparative study on the synthesis, stability, and catalytic activity of various iron pincer complexes with the general formula [(R-(PNP)-P-H)Fe(H) (CO) (BH4)] is reported, where R denotes the substituent of the terminal PR2-groups (R = Bu-t, Cy, Pt-i, Ph, Et). By the example of the synthesized precatalysts, it is shown that the nature of the ligands has a surprising influence on the catalytic properties of the complexes. Bulky ligands and less electron donating ligands affect the stability of the complexes, which preferably react under the loss of CO or H-2 to deactivated products. In return, the reduced steric demand and the strong sigma-donating properties of the Et-substituted precatalyst (2a) lead to an improved activity in the hydrogenation of esters to alcohols, compared to that of the previously reported Pr-i-substituted-complexes. The improved activity of complex 2a is clearly demonstrated in the direct hydrogenation of amides to alcohols and amines under mild conditions.
