    摘要:
    马来酸和富马酸衍生物与基于N,P配体的铱催化剂的不对称加氢为手性对映体富集的琥珀酸酯提供了一条有效途径。开发了一种新的衍生自2,6-二氟苯基取代的吡啶-次膦酸酯配体的催化剂,该催化剂能够将各种范围的2-烷基和2-芳基马来酸二酯转化为具有高对映体纯度的琥珀酸酯。顺式/反式底物的混合物可以以对映收敛的方式被氢化,具有高的对映选择性,并进一步扩大了这种转化的范围。该产品是有价值的手性结构单元,具有许多生物活性化合物(例如金属蛋白酶抑制剂)中发现的结构基序。

    Decarboxylative olefination of potassium benzoates via bimetallic catalysis strategy
    摘要:
    A novel synthesis of styrene derivatives through decaroxylative olefination of potassium benzoates with alkynes using Pd(2)dba(3)/CuBr as catalyst system has been developed. The protocol proceeded smoothly and in most cases Z-alkene was the main product. Electron-rich potassium benzoates reacted more efficiently than those of electron-deficient substrates. Heteroaromatic and electron-deficient aryl alkynes were not consistent with this transformation.[GRAPHICS].

  • 1-(2-Iodophenyl)-1H-tetrazole as a ligand for Pd(II) catalyzed Heck reaction
    作者:Arun Kumar Gupta、Chung Hyun Song、Chang Ho Oh
    DOI:10.1016/j.tetlet.2004.03.162
    日期:2004.5
    1-(2-Iodophenyl)-1H-tetrazole 2 was synthesized by the reaction of 2-iodoaniline, sodium azide and triethyl orthoformate in acetic acid. The newly synthesized ligand 2 was successfully used in Heck reaction to give the cross-coupled products in excellent yields.

  • Pd-Catalyzed desulfitative arylation of olefins by <i>N</i>-methoxysulfonamide
    作者:Subhadra Ojha、Niranjan Panda

    日期:——
    A novel Pd-catalyzed protocol for the desulfitative Heck-type reaction of N-methoxy aryl sulfonamides with alkenes was reported. The cross-coupling reaction was performed successfully with a variety of olefins to obtain aryl alkenes. Different substituents on the aromatic ring of N-methoxysulfonamides were also found to be compatible with the reaction conditions. Expectedly, the reaction proceeds through
    报道了一种用于N-甲氧基芳基磺酰胺与烯烃的脱硫 Heck 型反应的新型 Pd 催化方案。与多种烯烃成功地进行了交叉偶联反应,得到了芳基烯烃。N-甲氧基磺酰胺芳环上的不同取代基也被发现与反应条件相容。预期,该反应通过 CuCl 2促进氮自由基的产生和随后在热条件下脱磺酰化以提供用于 Pd 催化的偶联反应的芳基自由基进行。N-甲氧基磺酰胺被进一步开发用于在CuCl 2存在下合成对称联芳基化合物。
  • Recyclable and reusable PdCl<sub>2</sub>(PPh<sub>3</sub>)<sub>2</sub>/PEG-400/H<sub>2</sub>O system for the hydrophenylation of alkynes with sodium tetraphenylborate
    作者:Rong Liu、Tingli Zhang、Bin Huang、Mingzhong Cai
    DOI:10.1177/1747519820934379
    日期:2021.1

    A stable and efficient PdCl2(PPh3)2/PEG-400/H2O catalytic system for the hydrophenylation reaction of alkynes has been developed. In the presence of 3 mol% PdCl2(PPh3)2 and 2 equiv. of HOAc, the hydrophenylation of both terminal and internal alkynes with sodium tetraphenylborate proceeded smoothly in a mixture of PEG-400 and water at room temperature or 50 °C to afford a variety of phenyl-substituted alkenes in moderate to high yields. The isolation of the products was easily performed by extraction with petroleum ether, and the PdCl2(PPh3)2/PEG-400/H2O system could be readily recycled and reused six times without apparent loss of catalytic activity.
