    Several mononuclear ruthenium(IV) complexes with phosphinous acid ligands [RuCl2(η3:η3-C10H16)(PR2OH)] have been synthesized (78–86% yield) by treatment of the dimeric precursor [RuCl(μ-Cl)(η3:η3-C10H16)}2] (C10H16 = 2,7-dimethylocta-2,6-diene-1,8-diyl) with 2 equivalents of different aromatic, heteroaromatic and aliphatic secondary phosphine oxides R2P(O)H.

  • Photoiodocarboxylation of Activated C═C Double Bonds with CO<sub>2</sub> and Lithium Iodide
    作者:Rossella Mello、Juan Camilo Arango-Daza、Teresa Varea、María Elena González-Núñez

    日期:2018.11.2
    The photolysis at 254 nm of lithium iodide and olefins 1 carrying an electron-withdrawing Z-substituent in CO2-saturated (1 bar) anhydrous acetonitrile at room temperature produces the atom efficient and transition metal-free photoiodocarboxylation of the CC double bond. The reaction proceeds well for terminal olefins 1 to form the new C–I and C–C σ-bonds at the α and β-positions of the Z-substituent
    室温下,在CO 2饱和(1 bar)无水乙腈中,带有吸电子Z取代基的碘化锂和烯烃1在254 nm处发生光解,产生C efficientC双键无原子和无过渡金属的光碘羧化反应。末端烯烃1的反应进展顺利,分别在Z取代基的α和β位置形成新的C-1和C-Cσ键,并受到极性质子溶剂或添加剂的强烈抑制。实验结果表明,反应通道通过乙腈中的自由基阴离子[CO 2 •– ],但在水性介质中涉及不同的中间体。CO的稳定离子四极和电子供体-受体相互作用2与碘化物阴离子在反应过程中起着至关重要的作用,因为它们允许CO 2渗透到乙腈中的阴离子的溶剂化壳中,而不是在水中。讨论了不同条件下所涉及的反应路径和反应中间体。
  • α-Hydroxy Acid Amides. A Convenient Synthesis

  • Synthesis of Aliphatic (S)-α-Hydroxycarboxylic Amides using a One-Pot Bienzymatic Cascade of Immobilised Oxynitrilase and Nitrile Hydratase
    作者:Sander van Pelt、Fred van Rantwijk、Roger A. Sheldon
    DOI:10.1002/adsc.200800625
    日期:2009.2
    Abstractmagnified imageA one‐pot bienzymatic cascade combining a hydroxynitrile lyase (Manihot esculenta, E.C. 4.1.2.10) and a nitrile hydratase (Nitriliruptor alkaliphilus, E.C. 4.2.1.84) for the synthesis of enantiopure aliphatic α‐hydroxycarboxylic amides from aldehydes is described. Both enzymes were immobilised as cross‐linked enzyme aggregates (CLEAs). Stability tests show that the nitrile hydratase CLEAs are sensitive to water‐immiscible organic solvents as well as to aldehydes and hydrogen cyanide (HCN), but are remarkably stable and show useful activity in acidic aqueous environments of pH 4–5. The cascade reactions are consequently carried out by using a portionwise feed of HCN and moderate concentrations of aldehyde in acidic aqueous buffer to suppress the uncatalysed hydrocyanation background reaction. After optimisation, this method was used to synthesise five different kinds of aliphatic α‐hydroxycarboxylic amides from the corresponding aldehydes with good yields and with enantiomeric purities comparable to those obtained for the α‐hydroxynitriles in the microaqueous hydrocyanation using hydroxynitrile lyase and an excess of HCN.
