    摘要:
    AbstractCatalytic systems combining ortho‐(dimesitylboryl)phenylphosphines and palladium precursors have been evaluated in the Suzuki–Miyaura couplings of chloro‐N‐heterocycles, in particular 2‐chloropyridines, with arylboronic acids. The Lewis basic character of the substrates does not interfere with the Lewis acidic site of the ligands, even for a substrate featuring free NH2 groups. The influence of several reaction parameters has been studied and the ortho‐dimesitylboryl moiety was actually found to substantially enhance the catalytic performance. The role of this group has been examined using preformed phosphine‐borane/Pd complexes and the formation of an original phosphine/η4‐boratabutadiene complex has been identified as a possible deactivation pathway. Regioselective coupling of 2,6‐dichloro‐3‐nitropyridine with phosphine‐borane/Pd catalysts has also been explored, and sequential double cross‐couplings were found to give a direct and efficient access to unsymmetrical 2,6‐diarylpyridines.magnified image

  • Palladium(0)-Alkene Bis(triarylphosphine) Complexes as Catalyst Precursors for the Methoxycarbonylation of Styrene

    spectra. Together with the nonfluorous complexes [Pd(0)(PPh3)2(alkene)] (alkene = C2H4, (NC)2CC(CN)2, NCC(H)C(H)CN, MA, or benzoquinone) these were evaluated as catalyst precursors in the methoxycarbonylation of styrene. The nonfluorous C2H4 and MA complexes gave the highest conversions (the turnover number (TON) was 120; the (average) turnover frequency (TOF) amounted to 80 h-1). The fluorous complex

    dihydrogen activation (hydrogenolysis of one Pd-N bond), subsequent hydro-palladation of the alkyne, followed by addition of N-H to palladium, reductive coupling of vinyl and hydride and, finally, substitution of the product alkene by the alkyne substrate. Under hydrogen-limiting conditions, side reactions occur, that is, formation of catalytically inactive palladacycles by oxidative alkyne coupling. Furthermore

    Dihydroanthracene derivatives (1–6) containing imide (1–3) and amine (4–6) functions have been used for the stabilization of palladium nanoparticles, starting from Pd(0) and Pd(II) organometallic precursors. Well-dispersed nanoparticles of mean size in the range ca. 1.9 to 3.6 nm could be obtained using Pd(0) precursors (PdLc and PdLd, where L = 1–6 and c and d mean the organometallic precursor involved

    rate-determining steps. By monitoring the reaction with NMR, we observed the presence of a coordinated formate anion and found that part of the maleic anhydride remains coordinated during the reaction. From these observations, we propose a mechanism in which hydrogen transfer from coordinated formate anion to zerovalent palladium(NHC)(MA)(alkyne)-complex is followed by migratory insertion of hydride
    当使用零价 (NHC)(马来酸酐)-配合物作为预催化剂和甲酸三乙基作为氢供体时,炔烃向 (Z)-烯烃的转移半氢化显示出优异的化学和立体选择性。对反应条件下动力学的研究表明,底物正序和催化剂和氢供体的一级顺序被破坏。对氢供体的标记研究表明,甲酸的两个氢都显示出主要的动力学同位素效应,表明质子和氢化物转移是单独的速率决定步骤。通过用 NMR 监测反应,我们观察到配位甲酸阴离子的存在,并发现部分马来酸酐在反应过程中保持配位。从这些观察中,我们提出了一种机制,其中氢从配位甲酸阴离子转移到零价(NHC)(MA)(炔)-络合物,随后是氢化物的迁移插入,之后产物烯烃通过从三乙基铵阳离子的质子转移释放。观察到的高选择性的解释在于强配位溶剂和炔烃之间对 Pd(烯烃)-中间体的竞争。

    ortho-(Dimesitylboryl)phenylphosphines 1 and 2 were applied in Pd-catalyzed Suzuki-Miyaura C-C couplings. Coordination studies were performed in order to rationalize the relationship between structure and reactivity. Full characterization of a Pd(0) complex derived from 1 has evidenced a new coordination mode for phosphine-arylboranes involving secondary pi-interaction between one of the mesityl groups at boron
