    Palladium-catalyzed alkenation of thiophenes and furans by regioselective C–H bond functionalization
    摘要:
    A palladium-catalyzed direct alkenation of thiophenes and furans has been developed in the presence of AgOAc and pyridine. A variety of olefinic substrates such as acrylates, acrylamides, and acrylonitrile can perform the direct oxidative coupling reactions with various thiophenes and furans to give the mono-alkenylated products in good yields. In most cases, the (E)-isomers were isolated as the major products. (C) 2009 Elsevier Ltd. All rights reserved.

  • 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(化物,化物或化物)与活性烯烃在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,单体物质是催化循环中的催化活性物质。

    Dichloro-bis(aminophosphine) complexes of palladium with the general formula [(P(NC5H10)3−n(C6H11)n})2Pd(Cl)2] (where n = 0–2) are easily accessible, cheap and air stable, highly active and universally applicable C–C cross-coupling catalysts, which exhibit an excellent functional group tolerance. The ligand composition of amine-substituted phosphines (controlled by the number of P–N bonds) was found

    A low viscosity ionic liquid [bmim]NTf 2 was successfully used as a reaction medium in Pd-catalyzed Mizoroki-Heck, Suzuki-Miyaura and Stille coupling reactions. The yields are good to high, and comparable to those reported previously for high viscosity ionic liquids, such as [bmim]PF 6 and [bmim]BF 4 . The products are readily separated and a reaction medium containing the Pd-carbene catalyst was successfully
