  • Palladium nanoparticles as reusable catalyst for the synthesis of <i>N</i>-aryl sulfonamides under mild reaction conditions
    作者:Mehdi Khalaj、Majid Ghazanfarpour-Darjani、Mohamad Reza Talei Bavil Olyai、Sakineh Faraji Shamami
    DOI:10.1080/17415993.2015.1122010
    日期:2016.3.3
    An efficient palladium nanoparticles-catalyzed N-arylation of sulfonamides and sulfonyl azides is described. This procedure serves as an active protocol for intermolecular C–N bond formation using Pd(OAc)2 in PEG-400 under air. Aryl bromides and triflates react at 35°C, while aryl chlorides require heating to 50°C and give the desired products only in low yields. This reaction proceeds smoothly in
    描述了一种有效的钯纳米粒子催化的磺酰胺和磺酰叠氮化物的 N-芳基化。该过程用作在空气中使用 PEG-400 中的 Pd(OAc)2 形成分子间 C-N 键的主动协议。芳基溴化物和三氟甲磺酸酯在 35°C 下反应,而芳基氯化物需要加热到 50°C,并且只能以低产率得到所需产物。该反应使用低催化剂负载以可接受的产率平稳进行。图形概要
  • PROCESS FOR PRODUCING AROMATIC AMINES
    申请人:TAKASAGO INTERNATIONAL CORPORATION
    公开号:US20020035295A1
    公开(公告)日:2002-03-21
    The present invention provides an activator in arylamination using a palladium compound as a catalyst, which is superior to conventional phosphines in stability and performance. With the phosphine sulfide as an activator, an arylamination reaction achieves improved selectivity to produce a desired aromatic amine in an obviously increased yield as compared with a reaction using the corresponding phosphine compound. Moreover, the phosphine sulfide of the invention is impervious to oxidation and exists stably in air and therefore sufficiently withstands use on an industrial scale.
    本发明提供了一种在芳基化反应中使用钯化合物作为催化剂的活化剂,其在稳定性和性能方面优于传统的膦化合物。通过使用膦硫化物作为活化剂,芳基化反应实现了改善的选择性,以明显增加的产量生产所需的芳香胺,与使用相应的膦化合物的反应相比。此外,本发明的膦硫化物不受氧化影响,在空气中存在稳定,因此足以在工业规模上使用。
  • Synthesis of <i>N</i>-Arylpyrazoles by Palladium-Catalyzed Coupling of Aryl Triflates with Pyrazole Derivatives
    作者:Shunsuke Onodera、Takuya Kochi、Fumitoshi Kakiuchi

    palladium-catalyzed coupling of aryl triflates with pyrazole derivatives is described. Using tBuBrettPhos as a ligand, the palladium-catalyzed C–N coupling of a variety of aryl triflates including ortho-substituted ones with pyrazole derivatives proceeded efficiently to give N-arylpyrazole products in high yields. 3-Trimethylsilylpyrazole was found to be an excellent pyrazole substrate for the coupling, and the corresponding
    描述了通过钯催化的芳基三氟甲磺酸酯与吡唑衍生物的偶合来合成N-芳基吡唑的方法。使用t BuBrettPhos作为配体,钯催化的各种芳基三氟甲磺酸酯(包括邻位取代的芳基三氟甲磺酸酯)与吡唑衍生物的C-N偶联有效地进行,以高收率得到N-芳基吡唑产物。发现3-三甲基甲硅烷基吡唑是偶联的极佳吡唑底物,相应的产物1-芳基-3-三甲基甲硅烷基吡唑也可作为合成N-芳基吡唑衍生物的很好模板,如在该区域的区域选择性卤化所证明的那样。吡唑环的3位,4位和5位。
  • Selective Arylation and Vinylation at the α Position of Vinylarenes
    作者:Yinjun Zou、Liena Qin、Xinfeng Ren、Yunpeng Lu、Yongxin Li、Jianrong (Steve) Zhou

    styrene and vinylarenes, the aryl and vinyl groups routinely insert at the β position. However, selective insertion at the αposition has been very rare. Herein, we provide a missing piece in the palette of Heck reaction, which gave >20:1 αselectivity. The key to our success is a new ferrocene 1,1′‐bisphosphane (dnpf) that carries 1‐naphthyl groups. Our mechanistic studies revealed that the high α selectivity
    在苯乙烯和乙烯基芳烃的分子间Heck反应中,芳基和乙烯基通常插入β位置。然而,在α位置的选择性插入非常罕见。在这里,我们在Heck反应的调色板中提供了一个缺失的片段,该片段给出了> 20:1的α选择性。我们成功的关键是带有1-萘基的新型二茂铁1,1'-双膦(dnpf)。我们的机理研究表明,较高的α选择性部分归因于dnpf的空间效应。dnpf的刚性和庞大的1-萘基在空间上不利于β插入。
