  • Copper promoted synthesis of diaryl ethers
    作者:Rajshekhar Ghosh、Ashoka G. Samuelson
    DOI:10.1039/b401179a
    日期:——
    An efficient protocol using copper based reagents for the coupling of aryl halides with phenols to generate diaryl ethers is described. A copper(I) complex, [Cu(CH3CN)4]ClO4, or the readily available copper(II) source, CuCO3·Cu(OH)2·H2O (in combination with potassium phosphate), can be used. Aryl halides and phenols with different steric and electronic demands have been used to assess the efficiency of the procedure. The latter source of copper gives better yields under all conditions.
    文中描述了一种利用基于铜的试剂实现芳基卤与酚偶联生成二芳基醚的高效协议。可以使用铜(I)配合物,例如[Cu(CH3CN)4]ClO4,或者易于获得的铜(II)源,即铜碳酸盐·氢氧化铜·水(结合磷酸钾)。根据不同的立体和电子需求,使用不同类型的芳基卤和酚来评估该过程的效率。在所有条件下,后一种铜源能够提供更好的产率。
  • Selective<i>Ortho</i>-Hydroxylation-Defluorination of 2-Fluorophenolates with a Bis(μ-oxo)dicopper(III) Species
    作者:Joan Serrano-Plana、Isaac Garcia-Bosch、Ryosuke Miyake、Miquel Costas、Anna Company
    DOI:10.1002/anie.201405060
    日期:2014.9.1
    The bis(μoxo)dicopper(III) species [CuIII2(μ‐O)2(m‐XYLMeAN)]2+ (1) promotes the electrophilic ortho‐hydroxylation–defluorination of 2‐fluorophenolates to give the corresponding catechols, a reaction that is not accomplishable with a (η2:η2‐O2)dicopper(II) complex. Isotopic labeling studies show that the incoming oxygen atom originates from the bis(μoxo) unit. Ortho‐hydroxylation–defluorination occurs
    双(μ-氧代)双铜(III)物种[Cu III 2(μ-O)2(m-XYL MeAN)] 2+(1)促进2-氟酚盐的亲电子邻羟基化-脱氟,得到相应的儿茶酚,反应不是accomplishable用(η 2:η 2 -O 2)亚铜(II)络合物。同位素标记研究表明,进入的氧原子源自bis(μ-oxo)单元。在分子内竞争中,与其他邻位取代基(例如氯或溴)选择性发生邻羟基化-脱氟。
  • Novel Electron-Rich Bulky Phosphine Ligands Facilitate the Palladium-Catalyzed Preparation of Diaryl Ethers
    作者:Attila Aranyos、David W. Old、Ayumu Kiyomori、John P. Wolfe、Joseph P. Sadighi、Stephen L. Buchwald
    DOI:10.1021/ja990324r
    日期:1999.5.1
    A general method for the palladium-catalyzed formation of diaryl ethers is described. Electron-rich, bulky aryldialkylphosphine ligands, in which the two alkyl groups are either tert-butyl or 1-adamantyl, are the key to the success of the transformation. A wide range of electron-deficient, electronically neutral and electron-rich aryl bromides, chlorides, and triflates can be combined with a variety
    描述了钯催化形成二芳基醚的一般方法。富含电子的、庞大的芳基二烷基膦配体,其中两个烷基是叔丁基或 1-金刚烷基,是转化成功的关键。使用氢化钠或磷酸钾作为碱,在 100 °C 的甲苯中,可以将各种缺电子、电子中性和富电子的芳基溴化物、氯化物和三氟甲磺酸酯与各种酚结合。膦配体庞大而碱性的性质被认为是提高二芳基醚从钯中还原消除的速率的原因。
  • Bridged bis(amidinate) lanthanide aryloxides: syntheses, structures, and catalytic activity for addition of amines to carbodiimides
    作者:Jing Tu、Wenbo Li、Mingqiang Xue、Yong Zhang、Qi Shen
    DOI:10.1039/c3dt33069a
    日期:——
    Various lanthanide aryloxide complexes supported by bridged bis(amidinate) ligand L, LLnOAr(DME) (L = Me3SiNC(Ph)N(CH2)3NC(Ph)NSiMe3, DME = dimethoxyethane, Ln = Y, Ar = 2,6-(Me)2C6H3 (1), 2,6-(iPr)2C6H3 (2), 2,6-(tBu)2-4-(Me)C6H2 (3); Ar = 2,6-(tBu)2-4-(Me)C6H2, Ln = Nd (4), Sm (5), Yb (6)) were synthesized, and complexes 1, 2 and 4–6 were characterized by single crystal X-ray diffraction. All the complexes are efficient precatalysts for catalytic addition of amines to carbodiimides. The catalytic activity is influenced by lanthanide metals and the aryloxide groups (Nd (4) ∼ Sm (5) < Y (3) ∼ Yb (6) and -2,6-(Me)2C6H3 < -2,6-(iPr)2C6H3 < -2,6-(tBu)2-4-(Me)C6H2). The catalytic addition reaction with 3 showed a good scope of substrates. The mechanism investigation revealed the real active intermediate being the monoguanidinate complexes supported by an aryloxide and an amidine-functionalized amidinate group, L′Ln[O2,6-(tBu)2-4-(Me)C6H2][RNCNHRN(Ar′)] (L′ = Me3SiNHC(Ph)N(CH2)3NC(Ph)NSiMe3, R = iPr, Ar′ = phenyl, Ln = Yb (8), Y (11); R = Cy, Ar′ = phenyl, Ln = Yb (10), Y (12); R = iPr, Ar′ = 4-ClC6H4, Ln = Yb (9)), which were isolated from the reactions of 6 (or 3) with amine and carbodiimide in a molar ratio of 1 : 1 : 1 and structurally characterized. The Ln-active group in the present precatalyst is a Ln–amidinate species, not the Ln–OAr group.
