  • Cross-Coupling Catalysis by an Anionic Palladium Complex
    作者:Felix Schroeter、Johannes Soellner、Thomas Strassner
    DOI:10.1021/acscatal.6b03655
    日期:2017.4.7
    Recent studies have shown that anionic palladium complexes are viable catalysts for a range of catalytic cross-coupling reactions. We present a one-step synthesis of the anionic “ligandless” palladium complex [NBu4][Pd(DMSO)Cl3] together with its crystal structure. This compound has been shown to be an active precatalyst in the Mizoroki–Heck reaction. Under Jeffery conditions, activated aryl chlorides
    最近的研究表明,阴离子络合物是用于一系列催化交叉偶联反应的可行催化剂。我们目前一步一步合成阴离子“无配体络合物[NBu 4 ] [Pd(DMSO)Cl 3 ]及其晶体结构。该化合物已被证明是Mizoroki-Heck反应中的活性预催化剂。在杰弗里条件下,活化的芳基化物可以偶联,收率高达94%,而无需其他配体。少量的存在对于产物形成是必需的。Amatore-Jutand型催化循环与本文介绍的结果一致。为了与已知的混合配合物[(pym-Im-Me)2 PdCl] [Pd(DMSO)Cl 3],已使用标准技术合成并表征了阳离子络合物[(pym-Im-Me)2 PdCl] PF 6(pym =嘧啶基,Im =咪唑啉-2-亚基)。

  • Pyrazine Functionalized Ag(I) and Au(I)-NHC Complexes are Potential Antibacterial Agents

    Antimicrobial resistance is an ever-increasing problem throughout the world and has already reached severe proportions. Bacteria can develop ways to render traditional antibiotics ineffective, raising a crucial need to find new antimicrobials with novel mode of action. We demonstrate here a novel class of pyrazine functionalized Ag(I) and Au(I)-NHC complexes as antibacterial agents against human pathogens that are resistant to several antibiotics. Complete synthetic and structural studies of Au(I) and Ag(I) complexes of 2-(1- methylimidazolium) pyrimidinechloride (L-1), 2,6-bis(1-methylimidazol)pyrazinechloride (L-2) and 2,6-bis(1-methyl imidazol) pyrazinehexa-fluorophosphate (L-3) are reported herein. Chloro[2,6-bis(1-methyl imidazol)pyrazine]gold(I), 2b and chloro [2,6-bis(1- methyl imidazol)pyrazine]silver(I), 2a complexes are found to have more potent antimicrobial activity than other synthesized compounds and several conventionally used antibiotics. Complexes 2b and 2a also inhibit the biofilm formation by Gram-positive bacteria, Streptococcus mutans and Gram-negative bacteria, Escherichia coli, causing drastic damage to the bacterial cell wall and increasing membrane permeability. Complexes 2b and 2a strongly binds to both Lys and Dap-Type peptidoglycan layers, which may be the reason for damage to the bacterial cell wall. Theoretical studies of all the complexes reveal that 2b and 2a are more reactive than other complexes, and this may be the cause of differences in antibacterial activity. These findings will pave the way towards developing a new class of antibiotics against different groups of conventional antibiotic-resistant bacteria.
    抗菌药耐药性是全世界日益严重的问题,目前已经达到了很严重的程度。 细菌可以开发出使传统抗生素失效的方法,因此亟需找到具有新作用模式的新型抗菌药。我们在此展示了一类新型吡嗪官能化 Ag(I) 和 Au(I)-NHC 复合物,可作为抗菌剂对付对多种抗生素产生耐药性的人类病原体。本文报告了 2-(1-甲基咪唑鎓)嘧啶盐酸盐(L-1)、2,6-双(1-甲基咪唑)吡嗪盐酸盐(L-2)和 2,6-双(1-甲基咪唑)吡嗪六氟磷酸盐(L-3)的 Au(I) 和 Ag(I) 复合物的完整合成和结构研究。研究发现,[2,6-双(1-甲基咪唑)吡嗪](I)2b 和[2,6-双(1-甲基咪唑)吡嗪](I)2a 复合物比其他合成化合物和几种常规抗生素具有更强的抗菌活性。络合物 2b 和 2a 还能抑制革兰氏阳性菌--变异链球菌和革兰氏阴性菌--大肠杆菌--形成生物膜,对细菌细胞壁造成严重破坏,并增加膜的渗透性。复合物 2b 和 2a 能与赖酸和 Dap 型肽聚糖层紧密结合,这可能是细菌细胞壁受损的原因。对所有复合物的理论研究表明,2b 和 2a 比其他复合物更具反应性,这可能是造成抗菌活性差异的原因。这些发现将为开发一类新的抗生素铺平道路,这种抗生素可以对付不同种类的传统抗生素耐药细菌。
  • Helical mono and dinuclear mercury(II) N-heterocyclic carbene complexes
    作者:Kwang-Ming Lee、Jack C.C Chen、Ivan J.B Lin
    DOI:10.1016/s0022-328x(00)00617-3
    日期:2001.1
    A series of mono and dicationic carbene precursors have been synthesized. Reactions of these precursors with Hg(OAc)(2) produce helical mononuclear and dinuclear mercury(II) carbene complexes. Five structures, including two ligand precursors and three mercury(II) carbene complexes have been analyzed by single crystal X-ray diffraction. Several intermediates have been identified during the course of reaction. Based on these observed intermediates, three different reaction pathways have been proposed. (C) 2001 Elsevier Science B.V.

    Synthesis, structures and photophysical properties of a series of neutral fac-[Re(CO)(3)(C boolean AND N)Cl] complexes, where C boolean AND N is a pyrimidine-functionalized N-heterocyclic carbene [3-methyl-1-(2-pyrimidine)imidazol-2-ylidene, 1; 3-n-butyl-1-(2-pyrimidine) imidazol-2-ylidene, 2; 3-benzyl-1-(2-pyrimidine) imidazol-2-ylidene, 3; 3-mesityl-1-(2-pyrimidine)-imidazol-2-ylidene, 4] are reported. These complexes have been characterized by H-1 NMR, C-13 NMR, elemental analysis, and IR spectra. Their electrochemical and photophysical behaviors, along with the X-ray crystal structures of 2 and 4, are also reported. In both degassed CH2Cl2 solutions and solid state at room temperature, complexes 1-4 exhibit the emissions at 515-570 nm. (C) 2012 Elsevier B.V. All rights reserved.
