    Two-Step Cyanomethylation Protocol: Convenient Access to Functionalized Aryl- and Heteroarylacetonitriles
    摘要:
    A two-step protocol has been developed for the introduction of cyanomethylene groups to metalated aromatics through the intermediacy of substituted isoxazoles. A palladium-mediated cross-coupling reaction was used to introduce the isoxazole unit, followed by release of the cyanomethylene function under thermal or microwave-assisted conditions. The intermediate isoxazoles were shown to be amenable to further functionalization prior to deprotection of the sensitive cyanomethylene motif, allowing access to a wide range of aryl- and heteroaryl-substituted acetonitrile building blocks.

    供体-受体共轭荧光团中的酸碱反应性强电荷转移发射。
    摘要:
    本文中我们报告了含有噻吩并噻吩单元的供体-受体(DA)分子的合成和酸响应发射特性。2-Arylthieno [3,2- b ]噻吩与N偶联-甲基苯并咪唑单元,形成对酸敏感的D-A型荧光团。D–A共轭的荧光团显示出对酸的强烈分子内电荷转移(ICT)发射。取代对其光物理性质及其溶剂依赖性的影响表明质子化的D–A分子中ICT的发射没有扭曲。讨论了2-芳基噻吩并噻吩作为供体的喹诺酮特性,因为它被认为有助于抑制激发态下的分子扭曲,因此降低了非辐射速率常数,从而导致强烈的ICT发射。酸碱敏感的三色发射也可以通过在供体部分引入碱敏感的酚基来实现。

  • Gold(<scp>i</scp>)-catalyzed cross-coupling reactions of aryldiazonium salts with organostannanes
    作者:Manjur O. Akram、Popat S. Shinde、Chetan C. Chintawar、Nitin T. Patil
    DOI:10.1039/c8ob00630j
    日期:——
    Gold(I)-catalyzed cross-coupling reactions of aryldiazonium salts with organostannanes are described. This redox neutral strategy offers an efficient approach to diverse biaryls, vinyl arenes and arylacetylenes. Monitoring the reaction with NMR and ESI-MS provided strong evidence for the in situ formation of Ph3PAuIR (R = aryl, vinyl and alkynyl) species which is crucial for the activation of aryldiazonium

  • Nitration of Heteroaryltrimethyltins by Tetranitromethane and Dinitrogen Tetroxide: Mechanistic Aspects, Scope and Limitations
    作者:Valérie Fargeas、Fabien Favresse、Didier Mathieu、Isabelle Beaudet、Pierre Charrue、Bruno Lebret、Marc Piteau、Jean-Paul Quintard

    日期:2003.5
    The nitration of 2-(trimethylstannyl)heteroarenes by tetranitromethane (TNM) or dinitrogen tetroxide has been shown to be possible when the HOMO energy of the heteroaryltin is high enough to allow the formation of the corresponding radical cation. The reaction proceeds through a charge-transfer complex between heteroaryltin and TNM, followed by a single-electron transfer, which is enhanced under sunlamp
    当杂芳基锡的 HOMO 能量足够高以允许形成相应的自由基阳离子时,四硝基甲烷 (TNM) 或四氧化二氮对 2-(三甲基甲锡烷基) 杂芳烃的硝化已被证明是可能的。该反应通过杂芳基锡和 TNM 之间的电荷转移复合物进行,然后是单电子转移,在太阳灯照射下增强。因此,通过该方法获得了2-硝基苯并[b]呋喃、2-硝基苯并[b]噻吩、2-硝基吡啶和2-硝基吲哚。然而,由于 HOMO 轨道的低能量,2-甲锡烷基化嘧啶或甲锡烷基化 1,3,5-三嗪的硝化已被证明是不可能的。(© Wiley-VCH Verlag GmbH & Co.

    The coupling reaction of aryl and vinyl iodides, bromides, and triflates with organostannanes can be effectively conducted using palladium on carbon as a source of Pd0. The yield and rate of reaction are significantly affected by the addition of copper iodide as co-catalyst and triphenylarsine as ligand.
