    摘要:
    关于氧化剂,醛和氢离子,通过N-溴芳基磺酰胺钠(N-溴胺)将脂族醛氧化为相应的羧酸是一级的。在298 K乙醛氧化中,主要的动力学同位素效应kHkD为4.91±0.14,溶剂同位素效应k(H2O)k(D2O)为0.43。母体磺酰胺的添加不影响该速率。六个取代的N-溴胺的还原反应在298 K下的反应常数为1.22。(ArSO 2 NH 2 Br)+被假定为反应性氧化物质。已经计算出水合醛和游离醛形式的氧化的独立速率常数。醛水合物的氧化速率与具有负反应常数的塔夫脱取代基常数很好地相关。提出了涉及从醛水合物到氧化剂的氢化物转移的机理。

  • Evaluation of Organic Hydride Donors as Reagents for the Reduction of Carbon Dioxide and Metal-Bound Formates
    作者:Timothy E. Elton、Graham E. Ball、Mohan Bhadbhade、Leslie D. Field、Stephen B. Colbran
    DOI:10.1021/acs.organomet.8b00600
    日期:2018.11.12
    A variety of organic hydride donors (OHDs) have been tested as reagents for the transfer of hydride to iron formato complexes in the activation and reduction of carbon dioxide. Theoretical calculations show that the selection of OHD and solvent is crucial when planning systems involving OHD cooperativity. Strong consideration is given to the likelihood that metal centers may deactivate formate to hydride
    已经测试了多种有机氢化物供体(OHD)作为在二氧化碳的活化和还原过程中将氢化物转移至甲酰铁络合物的试剂。理论计算表明,在计划涉及OHD合作性的系统时,选择OHD和溶剂至关重要。强烈考虑了金属中心可能使甲酸酯失活而发生氢化物侵蚀的可能性,因为通常而言,与有机甲酸酯或甲酸相比,与金属中心络合时,甲酸酯基团具有更多的共振稳定能。实验证明1,2-二氢吡啶不是有效的二氧化碳还原剂。
