  • Efficient Palladium(II) Catalysis under Air. Base-Free Oxidative Heck Reactions at Room Temperature or with Microwave Heating
    作者:Jonas Lindh、Per-Anders Enquist、Åke Pilotti、Peter Nilsson、Mats Larhed

    limitations of the base-free oxidative Heck reaction with arylboronic acids have been explored. Under our conditions, the dmphen−palladium(II)-catalyzed arylation proceeded with air or p-benzoquinone as reoxidants of palladium(0). We found that ambient temperature and mild aerobic conditions allow for the use of substrates sensitive to palladium(II)-catalyzed oxidation. Oxidative Heck couplings, employing
    已经探索了与芳基硼酸的无碱氧化Heck反应的范围和局限性。在我们的条件下,dmphen-钯(II)催化的芳基化反应以空气或对苯醌作为钯(0)的再氧化剂进行。我们发现环境温度和温和的好氧条件允许使用对钯(II)催化的氧化敏感的底物。使用不同的芳基硼酸的氧化性Heck偶联可与富电子和贫电子的烯烃平稳地进行区域选择性反应,即使使用二取代的甲基丙烯酸丁酯,敏感的丙烯醛和乙烯基硼酸酯,也能提供高收率。在小规模和50 mmol规模的批处理过程中,受控的微波处理都可将反应时间从数小时缩短至数分钟。
  • Catalysis with palladium colloids supported in poly(acrylic acid)-grafted polyethylene and polystyrene
    作者:David E Bergbreiter、Andrew Kippenberger、Zhenqi Zhong
    DOI:10.1139/v06-076
    日期:2006.10.1

    Grafts of poly(acrylic acid) on polyethylene powder (PE-g-PAA) or polystyrene (PS-g-PAA) can be used to support Pd(0) crystallites that function like a homogeneous Pd(0) catalyst in some reactions. These Pd–PE-g-PAA catalysts were active in allylic substitution reactions in the presence of added phosphine ligand. A catalyst analogous to the Pd–PE-g-PAA powder catalyst on polystyrene (Pd–PS-g-PAA) was similarly active for allylic substitution and could also be used in Heck reactions at 80–100 °C in N,N-dimethylacetamide (DMA). Analysis of the product solutions for Pd leachate and a correlation of the Pd leaching with product formation in the allylic substitution chemistry for both types of catalysts suggests that the active catalysts in these reactions are leached from the support. In the case of the allylic substitution reaction, external triphenylphosphine and substrate together are required for the chemistry and Pd leaching.Key words: catalysis, palladium, allylic substitution, grafted polystyrene, supported catalysts.

    在聚乙烯粉末(PE-g-PAA)或聚苯乙烯(PS-g-PAA)上接枝聚(丙烯酸)可用于支撑钯(0)结晶,在某些反应中可发挥均相钯(0)催化剂的作用。在添加膦配体的情况下,这些 Pd-PE-g-PAA 催化剂在烯丙基取代反应中具有活性。与聚苯乙烯上的 Pd-PE-g-PAA 粉末催化剂类似的催化剂(Pd-PS-g-PAA)在烯丙基取代反应中也具有类似的活性,并可在 80-100 °C 的 N,N-二甲基乙酰胺(DMA)中用于赫克反应。对产品溶液中的钯浸出物进行分析,以及钯浸出物与两种催化剂在烯丙基取代化学反应中生成的产品之间的相关性表明,这些反应中的活性催化剂是从载体中浸出的。在烯丙基取代反应中,化学反应和钯浸出需要外部三苯基膦和底物的共同作用。

    Heck-type coupling and conjugate addition by synergistically tuning the supporting ligand, the boronic acid to olefin ratio and other reaction conditions. Conjugate addition with selectivity >99% and Heck-type coupling with selectivity of up to 100%, 98% and 84% for acrylates, acrylamides and methyl vinyl ketone, respectively, could be achieved in the rhodium-catalyzed reactions of aryl boronic acids
    在甲苯-H(2)O双相系统中,已系统研究了膦-铑催化的芳基硼酸与α,β-不饱和羰基的反应中的Heck型偶联和共轭加成之间的竞争。除了铑的内在性质和羰基的烯醇化之外,发现铑上的膦支持配体,芳基硼酸与α,β-不饱和羰基的比例以及水相的pH值均显着影响竞争。因此,已经通过协同调节载体配体,硼酸与烯烃的比例和其他反应条件,开发了用于Heck型偶联和共轭物加成的高选择性铑基催化剂体系。共轭添加的选择性> 99%,Heck型偶联的选择性高达100%,

    catalytic cycle of the Heck reaction, their general existence as reactive intermediates (for example, in other reactions) cannot be excluded. On the contrary, they were shown to be thermally accessible. Compounds 1 and 2 show a smooth halide exchange with bromobenzene to yield their bromo derivatives in DMF at 100 degrees C. Experimental observations revealed that the halide exchange most probably proceeded

  • Aminophosphine Palladium Pincer Complexes for Suzuki and Heck Reactions
    作者:Jeanne L. Bolliger、Christian M. Frech
    DOI:10.2533/chimia.2009.23
    日期:——

    The aminophosphine-based pincer complexes [C6H3-2,6-NHP(piperidinyl)2}2Pd(Cl)] (2) and [C6H3-2,6-OP(piperidinyl)2}2Pd(Cl)] (3) are readily prepared from cheap starting materials by sequential addition of 1,1?,1?-phosphinetriyltripiperidine and 1,3-diaminobenzene or resorcinol to solutions of [Pd(cod)(Cl)2] (cod = cyclooctadiene) in toluene under N2 in 'one pot'. Compounds 2 and 3 proved to be not only excellent catalysts for the Suzuki and the Heck cross-coupling reactions, but they are also very convenient to use: The toluene solutions of the 'one-pot' syntheses can be used directly for the catalytic reactions, thereby saving the time-consuming isolation of the catalysts. The Suzuki cross-coupling reaction catalyzed by 2 and 3 can be performed in air at 100 °C in toluene of technical quality: in the presence of only 0.001mol% of catalyst, several electronically deactivated and sterically hindered aryl bromides are quantitatively coupled with phenylboronic acid within a few minutes of reaction time. Furthermore, complex 2 enables the use of activated and non-activated aryl chlorides as coupling partners in the Suzuki reaction. Compounds 2 and 3 have also been shown to be highly active and reliable Heck catalysts: Very low catalyst loadings and short reaction times are required for the quantitative coupling of several electronically deactivated and sterically hindered aryl bromides with various olefins at 140 °C. At increased temperatures, even electronically deactivated and sterically hindered aryl chlorides can be efficiently coupled with olefins in the presence of only 0.01 mol% of catalyst.
