    N-Metallacycles from [Cp*MX2]2 and Alkynylpyridines: Synthesis, Reaction Pathway, and Aromaticity
    摘要:
    The reaction of [Cp*MX2](2) (M = Rh or Ir, X = Cl, Br, or I) with alkynylpyridines afforded halogen-substituted N-metallacyclic complexes. The reaction pathway has been examined through deuterium labeling and other experiments and computational studies and is proposed to proceed via halide dissociation followed by attack at the alkyne. These N-metallacycles exhibit aromaticity and undergo Sonogashira coupling reactions.

  • The first Cu- and amine-free Sonogashira-type cross-coupling in the C-6-alkynylation of protected 2′-deoxyadenosine

    The Sonogashira cross-coupling reaction offers a convenient route to C(sp)–C(sp2) bond formation. Although the Sonogashira reaction has traditionally been carried out in the presence of Pd catalyst and a co-catalyst of Cu(I) salt, the use of Cu(I) salt is often not efficient because it leads to the formation of unwanted side-products. This has prompted interest in recent years in the development of
    Sonogashira交叉偶联反应为到达C(sp)–C(sp 2)键的形成。尽管Sonogashira反应传统上是在Pd催化剂和Cu(I)盐的助催化剂存在下进行的,但是Cu(I)盐的使用通常效率不高,因为它会导致形成不需要的副产物。近年来,这引起了人们对开发无Cu Sonogashira交叉偶联反应条件的兴趣。另外,用于核苷衍生物的炔基化的无铜Sonogashira交叉偶联条件的开发在很大程度上仍未开发。本文中,我们证明了无铜和无胺的Sonogashira型交叉偶联可成功实现芳基溴化物和杂芳基溴化物的炔基化。首次,我们扩展了这种方法,用于在C-6位保护的2'-脱氧腺苷进行炔基化。
  • Synthesis, Characterizations, Crystal Structure, DFT, and Hirshfeld Surface Analysis of 4-Cyclohexyl-1-(thiophene-2-carbonyl)thiosemicarbazide

    The crystal structure of the thiosemicarbazide derivative 4-cyclohexyl-1-(thiophene-2-carbonyl)thiosemicarbazide (ChtcTSC), C12H17N3OS2, is reported here. The title compound ChtcTSC has been characterized by various physicochemical techniques viz UV–Vis., Infrared, and NMR. It crystallizes in the monoclinic system having space group P21/c. The dihedral angle between the thiophene and cyclohexyl rings is 60.7(4)°. The crystal packing is established by intermolecular N–H⋯O packing interactions involving a three-center donor hydrogen bond between the keto oxygen atom of the thiophene group and H atoms belonging to the hydrazine group which links the molecules into chains along the (011) plane of the unit cell. Hydrogen bonds between the hydrazine hydrogen atom and one of the thiophene groups and C–H⋯Cg π -ring interactions provide added stability to the crystal packing. The fingerprint plots associated with Hirshfeld surface analysis indicate that there are different types of weak interactions viz. O⋯H–C, O⋯H–N, and S⋯H–C. The geometry optimization has been performed using the DFT method, and geometrical parameters thus obtained for ChtcTSC correlate with the single-crystal X-ray data. The TD-DFT study showed a small HOMO and LUMO energy gap of 2.869 eV. The electronic transition from the ground state to the excited state due to a transfer of electrons from HOMO to LUMO levels is mainly associated with the n → π* transition. The crystal structure of 4-cyclohexyl-1-(thiophene-2-carbonyl)thiosemicarbazide (ChtcTSC) is reported here where the title compound ChtcTSC has been characterized by various physiochemical techniques including UV–Vis., Infrared, NMR, DFT and Hirshfeld surface analysis.
    本文报告了硫代氨基脲衍生物 4-环己基-1-(噻吩-2-羰基)硫代氨基脲(ChtcTSC)(C12H17N3OS2)的晶体结构。标题化合物 ChtcTSC 已通过紫外可见光、红外线和核磁共振等各种理化技术进行了表征。它在单斜体系中结晶,空间群为 P21/c。噻吩环和环己基环之间的二面角为 60.7(4)°。晶体的堆积是由分子间的 N-H⋯O 堆积相互作用形成的,其中涉及噻吩基团的酮氧原子和属于肼基团的 H 原子之间的三中心供体氢键,该氢键将分子沿单胞的 (011) 平面连接成链。肼氢原子和其中一个噻吩基团之间的氢键以及 C-H⋯Cg π - 环相互作用增加了晶体堆积的稳定性。与 Hirshfeld 表面分析相关的指纹图表明,存在不同类型的弱相互作用,即 O⋯H-C、O⋯H-N 和 S⋯H-C。使用 DFT 方法对 ChtcTSC 进行了几何优化,由此获得的几何参数与单晶 X 射线数据相关。TD-DFT 研究表明,该化合物的 HOMO 和 LUMO 能隙较小,分别为 2.869 eV 。由于电子从 HOMO 水平转移到 LUMO 水平,从基态到激发态的电子转变主要与 n → π* 转变有关。本文报告了 4-环己基-1-(噻吩-2-羰基)硫代氨基甲酰肼(ChtcTSC)的晶体结构,并通过紫外可见光、红外、核磁共振、DFT 和 Hirshfeld 表面分析等多种理化技术对标题化合物 ChtcTSC 进行了表征。

    Dearomatization reactions provide a rapid approach to construct complicated molecules that are difficult to synthesize by traditional methods from simple aromatic compounds. Herein, we report an efficient dearomative [3+2] cycloaddition reaction of 2-alkynyl pyridines with diarylcyclopropenones, leading to the synthesis of densely functionalized indolizinones in moderate to good yields under metal-free

    Carbenes (R1R2C:) like radicals, arynes and nitrenes constitute an important family of neutral, high-energy, reactive intermediates—fleeting chemical entities that undergo rapid reactions. An alkyne (R3C≡CR4) is a fundamental functional group that houses a high degree of potential energy; however, the substantial kinetic stability of alkynes renders them conveniently handleable as shelf-stable chemical
    卡宾烯 (R1R2C:) 与自由基、芳烃和硝烯一样,构成了一个重要的中性、高能、反应性中间体家族——经历快速反应的转瞬即逝的化学实体。炔烃 (R3C≡CR4) 是一个基本官能,具有很高的势能;然而,炔烃的大量动力学稳定性使其可以作为耐贮存的化学商品方便地处理。在炔烃的高电位(即热力学)能量的推动下,直接从炔烃生成无金属卡宾的能力将构成相当大的进步。我们在这里报告说,这可以通过简单地加热 2-炔基亚氨基杂环(一种含有亲核氮原子的环状化合物)与亲电炔烃的混合物来实现。我们证明了该工艺的相当普遍性:许多耐贮存的炔烃亲电试剂与许多类别的(2-炔基)杂环亲核试剂结合以产生卡宾中间体,这些中间体立即经历多种类型的转化,从而为各种杂环产品提供简单实用的机会。描述了反应的关键机制方面。
