    摘要:
    铁为痕量钯提供动力 钯 (Pd) 是化学催化的支柱。贵金属具有锻造碳-碳 (CC) 键的诀窍。汉达等人。现在报告说,当与铁混合在特定制剂中时,仅百万分之一的 Pd 就足以催化形成 CC 键的 Suzuki 偶联反应。表面活性剂的加入使反应在水中进行。该协议预示着在药物和农用化学品合成中保护 Pd 是个好兆头。科学,这个问题 p。1087 铁制剂显着降低了催化形成 CC 键的常见反应所需的钯量。今天大多数过渡金属催化交叉偶联化学的使用依赖于昂贵数量的钯 (Pd)。在这里,我们报告说,由天然含有百万分之一 (ppm) 水平 Pd 的廉价 FeCl3 形成的纳米粒子可以催化 Suzuki-Miyaura 反应,包括涉及极具挑战性的反应伙伴的情况。纳米胶束用于溶解反应物并将反应伙伴传递给 Fe-ppm Pd 催化剂,从而形成碳-碳键。新形成的催化剂可以在环境温度下分离和储存。含有表面活性剂和催化剂

  • Synthesis of Unsaturated Organotrifluoroborates via Wittig and Horner−Wadsworth−Emmons Olefination
    作者:Gary A. Molander、Ruth Figueroa
    DOI:10.1021/jo060863w
    日期:2006.8.1
    stereoselective synthesis of unsaturated organotrifluoroborates by using the Wittig and Horner−Wadsworth−Emmons olefination is described. These reactions were general for both alkyl- and aryltrifluoroborates. The synthesis of di- and trisubstituted olefins was achieved by using formyl- and acetyl-substituted organotrifluoroborates. The products were isolated in moderate to excellent yield. The Wittig reaction

  • Suzuki−Miyaura Cross-Coupling Reactions of Benzyl Halides with Potassium Aryltrifluoroborates
    作者:Gary A. Molander、Maxwell D. Elia
    DOI:10.1021/jo061699f
    日期:2006.11.1
    [GRAPHICS]The palladium-catalyzed cross-coupling of potassium aryltrifluoroborates with benzylic halides occurs in good yield with high functional group tolerance. The increased stability of potassium aryltrifluoroborates compared to other boron coupling partners makes this an effective route to functionalized methylene-linked biaryl systems.
  • Functionalization of Organotrifluoroborates: Reductive Amination
    作者:Gary A. Molander、David J. Cooper
    DOI:10.1021/jo800383e
    日期:2008.5.1
    Herein we report the conversion of aldehyde-containing potassium and tetrabutylammonium organotrifluoroborates to the corresponding amines through reductive amination protocols. Potassium formate facilitated by catalytic palladium acetate, sodium triacetoxyborohydride, and pyridine borane have all served as effective hydride donors, reducing the initially formed imines or iminium ions to provide the corresponding amines.
  • Wittig reaction of formyl-substituted organotrifluoroborates and stabilized phosphonium ylides in an aqueous medium
    作者:Gary A. Molander、Roberta A. Oliveira
    DOI:10.1016/j.tetlet.2007.11.205
    日期:2008.2
    The synthesis of unsaturated organotrifluoroborates using the Wittig alkenation is described. These transformations to disubstituted alkenes were achieved by using formyl-substituted organotrifluoroborates and stabilized ylides using water as a solvent. The products were isolated in moderate to excellent yields and the reaction gave preferentially the E-isomer. (c) 2007 Published by Elsevier Ltd.
  • <sup>1</sup> H, <sup>13</sup> C, <sup>19</sup> F and <sup>11</sup> B NMR spectral reference data of some potassium organotrifluoroborates
    作者:Roberta A. Oliveira、Ricardo O. Silva、Gary A. Molander、Paulo H. Menezes
    DOI:10.1002/mrc.2467
    日期:2009.10
    Complete (1)H, (13)C, (19)F and (11)B NMR spectral data for 28 potassium organotrifluoroborates are described. The resonance for the carbon bearing the boron atom is described for most of the studied compounds. A modified (11)B NMR pulse sequence was used and better resolution was observed allowing the observation of (11)B-(19)F coupling constants for some of the studied compounds.
