    烷基钴氧肟中顺式作用的研究
    摘要:
    已合成了39种烷基钴肟(其中许多是新的),并用三种不同的二肟配体dmgH,dpgH和chgH进行了表征。chgH钴肟化合物是首次从ClCo(chgH)2 Py络合物合成的。已经针对所有三个系列的钴肟建立了使用柱色谱提供分析纯产物的快速纯化程序。甲醇是研究钴-碳电荷转移(Co-C CT)谱带的最佳溶剂,因为烷基钴肟在该溶剂中具有显着的最大值。对于MeCo(dpgH)2 Py,Co-C CT波段无法解析;一个λ最大的453.6纳米值提出了它。473 nm的文献价值令人怀疑。λ的变化对于所有三个系列的钴肟,随着烷基链长度的增加,max值惊人地相似。13 C-光谱显示,在P α经历最顺影响和P β最少。所述顺影响chgH配体的能力已被发现是可忽略的在烷基链上以及在P(相比于dpgH)β和P γ碳。1 H-NMR研究表明,顺式影响最受钴结合的亚甲基质子的影响,其次是Pα和Pβ。有趣的是,在所有十三种

    烯丙基和丙二烯基钴肟:性质和与四氰基乙烯的反应
    摘要:
    烯丙基钴氧肟的依赖温度的1 H nmr光谱显示了动态过程的特征,其中两种可能的σ-烯丙基钴氧肟配合物之间发生交换。这归因于两个过程:烯丙基二(二恶英)钴(III)配合物经历单分子反应,该反应涉及在轴向水配体丧失后形成的瞬时η-烯丙氧肟。烯丙基双(二恶英酮)吡啶钴盐(III)配合物发生双分子反应,其中S H 2'攻击钴氧肟(II)络合物(以杂质形式存在)攻击烯丙基的δ-碳并取代钴氧肟(II))的碳原子。后者的机制也可以与αlylaquabis(dioximato)cobaIt(III)配合物一起起作用。在没有形成η-烯丙基钴肟的条件下,即。在适当的轴向配体存在下,σ-烯丙基钴肟与C 2(CN)4反应,得到3,3,4,4-四氰基环戊基钴肟。反式-肉桂基双(二甲基乙二酰肟基)-咪唑钴(III)与C 2(CN )的反应形成反-双(二甲基乙二酰肟基)咪唑-(3,3,4,4-四氰基-2-苯基环戊基)钴

  • Photoredox/Cobalt Dual‐Catalyzed Decarboxylative Elimination of Carboxylic Acids: Development and Mechanistic Insight
    作者:Kaitie C. Cartwright、Ebbin Joseph、Chelsea G. Comadoll、Jon A. Tunge

    日期:2020.9.25
    Recently, dual‐catalytic strategies towards the decarboxylative elimination of carboxylic acids have gained attention. Our lab previously reported a photoredox/cobaloxime dual catalytic method that allows the synthesis of enamides and enecarbamates directly from N‐acyl amino acids and avoids the use of any stoichiometric reagents. Further development, detailed herein, has improved upon this transformation's
    近来,用于羧酸脱羧消除的双重催化策略已引起关注。我们的实验室以前曾报道过光氧化还原/双催化方法,该方法可直接从N酰基氨基酸合成酰胺和烯甲酸酯,并避免使用任何化学计量试剂。本文详述的进一步开发改进了这种转化的用途,进一步的实验为反应机理提供了新的见解。这些新的发展和见识有望帮助扩大光氧化还原/双催化系统。
  • Organocobaloximes with Mixed Dioxime Equatorial Ligands:  A Convenient One-Pot Synthesis. X-ray Structures and Cis−Trans Influence Studies

    A simple and general route to the synthesis of organocobaloxime with mixed dioxime ligands, RCo(L)(dpgH)Py [L = dmgH and chgH] (R = Me-Dec), has been described. The crystal structure of four complexes, ClCo(L)(dpgH)Py and MeCo(L)(dpgH)Py [L = dmgH and chgH], is reported. The structural study reveals that both the nonclassical C−H···O as well as the classical O−H···O intermolecular hydrogen bonding
    已经描述了一种简单且通用的合成带有混合二氧配体RCo(L)(dpgH)Py [L = dmgH和chgH](R = Me-Dec)的有机的途径。报道了四种配合物ClCo(L)(dpgH)Py和MeCo(L)(dpgH)Py [L = dmgH and chgH]的晶体结构。结构研究表明,既存在非经典CHH··O,也存在经典OHH···O分子间氢键,并导致一维二聚或聚合物结构的形成。轴向吡啶配体中的1 H和13 C NMR配位位移显示与赤道配体化学位移具有明显的相关性。这些相关性可以借助振铃电流模型来合理化。

  • Synthesis, Characterization, and Variable-Temperature <sup>1</sup>H NMR Behavior of Organo-Bridged Dicobaloximes
    作者:B. D. Gupta、V. Vijaikanth、Veena Singh
    DOI:10.1021/om034273p
    日期:2004.4.1
    Organo-bridged dicobaloximes with four different dioximes Py(L)(2)CoCH2-R-CH2Co(L)(2)Py (L = dmgH, dpgH, chgH, and gH) have been synthesized and characterized by H-1 and C-13 NMR and FAB mass spectroscopy. The cis influencing order observed in dicobaloximes is similar to the previously observed order in monocobaloximes. The cyclic voltammetric results show that an irreversible single-step two-electron reduction of Co-III to Co-I takes place. The Co-C bond in 4a cleaves during crystallization and results in the formation of o-vinylbenzyl cobaloxime. The variable-temperature H-1 NMR study suggests that the Co-C bond rotation is restricted and its magnitude depends on both the nature of the bridging ligand and the dioxime.
  • Organocobaloximes with mixed dioxime equatorial ligands: a convenient one-pot synthesis. X-ray crystal structures of BnCoIII(dmgH)(dpgH)Py and BnCOIII(chgH)(dpgH)py

    日期:2001.5
    A simple and general route to the synthesis of organocobaloxime with mixed dioxime ligands, RCo(dmgH)(dpgH)Py and RCo(chgH)(dpgH)Py, has been described. The C-13-NMR chemical shifts have been analysed to see whether one dioxime wing has any effect on the other dioxime wing. The first crystal structure of an organocobaloxime with mixed dioxime ligand in the same complex, BnCo(dmgH)(dpgH)Py and BnCo(chgH)(dpgH)Py, is reported. (C) 2001 Published by Elsevier Science B.V.
