  • A novel CC bond forming reaction of aryl-and alkenylsilanols. A halogen-free Mizoroki-Heck type reaction
    作者:Kazunori Hirabayashi、Yasushi Nishihara、Atsunori Mori、Tamejiro Hiyama

    日期:1998.10
    When dimethyl(phenyl)silanol is subjected to on electron-deficient olefin in the presence of a stoichiometric amount of Pd(OAc)2, substitution of the CH bond of the olefin by a phenyl group on the silanol occurs in 52–86% yields. The reactions of several aryl- and alkenylsilanols with several olefins are also found to proceed in the system of 10 mol% of Pd(OAc)2, Cu(OAc)2 (3 mol), LiOAc (2 mol) to
    当在化学计算量的Pd(OAc)2存在下,二甲基(苯基)硅烷醇在缺电子的烯烃上受到作用,在52–86中,硅烷醇上的苯基取代了烯烃的CH键%产率。还发现几种芳基和链烯基硅烷醇与几种烯烃的反应在10 mol%的Pd(OAc)2,Cu(OAc)2(3 mol),LiOAc(2 mol)的体系中进行以得到相应的产物最高可达69%的产量。

    The reaction of dimethyl(phenyl)silanol with butyl acrylate in the presence of a stoichiometric amount of Pd(OAc)2 or by a combined use of 0.1 molar amount of Pd(OAc)2 and Cu(OAc)2/LiOAc (molar ratio 3/2) gave butyl cinnamate in 76% or 57% yield, respectively. The similar reaction with tributyl(phenyl)tin also proceeded in 77% yield. The organotin compound was shown to react faster than the silanol
    二甲基(苯基)硅烷醇与丙烯酸丁酯化学计量的 Pd(OAc)2 存在下或通过组合使用 0.1 摩尔 Pd(OAc)2 和 Cu(OAc)2/LiOAc(摩尔比)的反应3/2) 分别以 76% 或 57% 的产率得到肉桂酸丁酯。与三丁基(苯基)的类似反应也以 77% 的产率进行。有机锡化合物比硅烷醇反应更快,尽管试剂有时会引起不希望的均偶联,而与硅烷醇的反应不会产生这种副产物。
  • Palladium-catalyzed cross-coupling of aryl and alkenyl boronic acids with alkenes via oxidative addition of a carbonboron bond to palladium(O)

    those from arylboronic acids. Similar treatment of sodium tetraphenylborate (NaBPh4) with alkenes also affords the corresponding phenylated alkenes in high yields together with biphenyl and benzene as side products. Oxidative addition of a carbonboron bond to palladium(O), formed in situ, to give an organopalladium(II) species is assumed to be the key step of these cross-coupling reactions.
    在催化量的乙酸(II)和乙酸的存在下,芳基硼酸在25℃在乙酸中与烯烃反应,以高收率得到相应的芳基取代的烯烃。烯基硼酸在相似的条件下与烯烃反应,从而立体定向地生成相应的共轭二烯,但与芳基硼酸相比,产物收率较低。用烯烃对四苯硼酸(NaBPh 4)进行类似处理,还可以高收率得到相应的苯化烯烃,以及联苯和苯作为副产物。在原位形成的(O)上氧化碳键以得到有机钯(II)物种被认为是这些交叉偶联反应的关键步骤。

  • Stereoselective Synthesis of Conjugated 2,4-Alkadienoates via the Palladium-Catalyzed Cross-Coupling of 1-Alkenylboronates with 3-Bromo-2-alkenoates
    作者:Teiji Yanagi、Takayuki Oh-e、Norio Miyaura、Akira Suzuki

    (2E,4E)-, (2Z,4E)-, and (2E,4Z)-2,4-Alkadienoates can be synthesized in high yields by the cross-coupling of ethyl (E)-3-bromoacrylate, methyl (E)-3-bromo-2-methylpropenoate, ethyl (Z)-3-bromocrotonate,1-bromo-2-(ethoxycarbonyl)cyclohexene, and 4-bromocoumarin with 2-[(E)-1-alkenyl]-1,3,2-benzodioxaboroles or diisopropyl (Z)-1-hexenylboronate in the presence of 3 mol% of Pd(OAc)2, 6 mol% of PPh3, and 2 equivalents of Na2CO3 or K2CO3 in alcoholic solvents while retaining the original configuration of the double bonds in β-bromo esters and 1-alkenylboronates. Although the coupling reaction with 1-hexenylboronate with (Z)-3-bromoacrylate gave a mixture of ethyl (2Z,4E)- and (2E,4E)-nonadienoates in a ratio of 63 : 37, it was found that the use of bis(diphenylphosphino)ferrocene as a ligand of palladium brought about the stereoselective coupling under mild conditions.
    (2E,4E)-、(2Z,4E)- 和 (2E,4Z)-2,4-烷二烯酸酯可以通过乙基(E)-3-溴丙烯酸酯、甲基(E)-3-溴-2-甲基丙烯酸酯、乙基(Z)-3-溴丙烯酸酯、1--2-(乙氧羰基)环己烯和4-香豆素与2-[(E)-1-烯基]-1,3,2-苯并二氧硼烷二异丙基(Z)-1-己烯硼酸酯在3摩尔%的Pd(OAc)2、6摩尔%的PPh3和2当量的Na2CO3或K2CO3的存在下,在醇溶剂中交叉耦合合成,且保持β-酯和1-烯基硼酸酯中双键的原始构型。尽管1-己烯硼酸酯与(Z)-3-溴丙烯酸酯的耦合反应生成了63:37比率的乙基(2Z,4E)-和(2E,4E)-九烯酸酯的混合物,但发现使用双(苯基)烯作为配体在温和条件下能够实现立体选择性耦合。
