    摘要:
    在非常温和的条件下,Pd(0)借助Pd(II)裂解了各种芳基肼的未活化碳氮键。原位生成的芳基钯络合物很容易参与与烯烃的C–C键形成。这项研究提供了一种新的C-Pd键形成方式,它将在未来刺激钯催化交叉偶联的发展。

  • A Palladium NNC-Pincer Complex as an Efficient Catalyst Precursor for the Mizoroki−Heck Reaction
    作者:Go Hamasaka、Shun Ichii、Yasuhiro Uozumi
    DOI:10.1002/adsc.201800099
    日期:2018.5.2
    The Mizoroki−Heck reaction of aryl halides (iodides, bromides, or chlorides) with activated alkenes in the presence of a palladium NNC‐pincer complex at ppb to ppm loadings gave the corresponding internal alkenes in excellent yields. The total turnover number and turnover frequency reached up to 8.70×108 and 1.21×107 h−1 (3.36×103 s−1), respectively. The catalyst was applied in a ten‐gram‐scale synthesis
    芳族卤化物(碘化物,溴化物或氯化物)与活性烯烃在钯NNC-钳夹配合物(ppb)至ppm负载量下的Mizoroki-Heck反应得到了相应的内部烯烃,收率很好。总周转次数和周转频率分别达到8.70×10 8和1.21×10 7 h -1(3.36×10 3 s -1)。该催化剂用于UV-B防晒剂辛诺酸酯(2-乙基己基4-甲氧基肉桂酸酯)的10克级合成。反应速率分析,反应混合物的透射电子显微镜检查和中毒试验表明,单体钯物质是催化循环中的催化活性物质。
  • In Situ Generation of Palladium Nanoparticles: Reusable, Ligand-Free Heck Reaction in PEG-400 Assisted by Focused Microwave Irradiation
    作者:Zhengyin Du、Lin Bai、Wanwei Zhou、Fen Wang、Jin-Xian Wang
    DOI:10.1055/s-0030-1259310
    日期:2011.2
    A rapid and efficient Heck coupling reaction of aryl iodides with terminal olefins was conducted in PEG-400 at 120 ˚C in the presence of potassium carbonate and palladium nanoparticles formed in situ from palladium chloride under focused microwave irradiation. High to excellent product yields were achieved. The reaction medium and catalyst could be easily recycled at least five times without significant loss in reactivity.
    在聚乙二醇-400中,以120°C的温度,在碳酸钾和原位生成的钯纳米颗粒的存在下,利用聚焦微波辐射快速高效地进行芳基碘化物与末端烯烃的Heck偶联反应。获得了高至优异的产物收率。反应介质和催化剂至少可以回收五次,而反应活性几乎没有显著损失。
  • Hydrothermal Heck reaction catalyzed by Ni nanoparticles
    作者:Wu Zhang、Hongling Qi、Liusan Li、Xiang Wang、Jie Chen、Kaishan Peng、Zhenghua Wang
    DOI:10.1039/b900697d
    日期:——
    A novel environmentally benign Heck reaction using Ni nanoparticles as catalysts under hydrothermal conditions has been developed in the absence of phosphine ligands without the protection of an inert atmosphere. The results showed that the aryl iodides and bromides could carry out the coupling reaction with a variety of alkenes by hydrothermal treatment. More importantly, the cheap catalysts are stable under the reaction conditions and retain good to moderate activity for at least six successive runs without any additional activation treatment. This approach would be very useful from a practical viewpoint.
    开发了一种新型环保的Heck反应,采用Ni纳米粒子作为催化剂,在没有磷配体和惰性气氛保护的水热条件下进行。结果表明,芳基碘和溴可以与多种烯烃通过水热处理进行偶联反应。更重要的是,这种廉价的催化剂在反应条件下稳定,并且在至少六次连续反应中保持良好到适度的活性,无需额外的活化处理。从实用的角度来看,这种方法非常有用。
  • Novel isoxazoline ligand with ferrocene backbone: preparation and application in Heck reaction with water as solvent
    作者:Shuyan Yu、Zhiqin Zhang、Zhiyu Yu、Yongjia Shang
    DOI:10.1002/aoc.3176
    日期:2014.8
    Two novel isoxazoline N,N‐bidentate ligands with ferrocene backbone have been synthesized and employed for the palladium‐catalyzed Heck coupling reaction. Among them, 1,3‐bis‐(5‐ferrocenylisoxazoline‐3‐yl)benzene was found to be thermally stable and a highly effective ligand for Heck coupling reaction in neat water without N2 protection, affording the desired coupling products in good to excellent
    合成了两个具有二茂铁骨架的新型异恶唑啉N,N双齿配体,并将其用于钯催化的Heck偶联反应。其中,1,3-双(5-二茂铁基异恶唑啉-3-基)苯具有良好的热稳定性,是在没有N 2保护的纯水中进行Heck偶联反应的高效配体,可提供所需的偶联产物具有非对映选择性高的优异收率。发达的催化体系对于1,2-二取代的烯烃也很适用,而后者因其较大的空间位阻而较少参与Heck反应。版权所有©2014 John Wiley&Sons,Ltd.
  • Homeopathic Ligand-Free Palladium as a Catalyst in the Heck Reaction. A Comparison with a Palladacycle
    作者:André H. M. de Vries、Jan M. C. A. Mulders、John H. M. Mommers、Huub J. W. Henderickx、Johannes G. de Vries
    DOI:10.1021/ol035184b
    日期:2003.9.1
    [reaction: see text] Ligand-free Pd(OAc)(2) can be used as a catalyst in the Heck reaction of aryl bromides as long as the amount of catalyst is kept between 0.01 and 0.1 mol %. At higher concentrations palladium black forms and the reaction stops. The actual catalyst is monomeric. Palladacycles merely serve as a source of ligand-free palladium in Heck reactions of aryl bromides.
    [反应:见正文]只要催化剂的量保持在0.01至0.1 mol%之间,则无配体的Pd(OAc)(2)可以用作芳基溴化物的Heck反应中的催化剂。在较高浓度下会形成钯黑,反应会停止。实际的催化剂是单体的。在芳基溴化物的Heck反应中,Palladacycles仅充当不含配体的钯的来源。
