  • Radical annulations with nitriles: Novel cascade reactions of cyano-substituted alkyl and sulfanyl radicals with isonitriles
    作者:Carlo Maurizio Camaggi、Rino Leardini、Daniele Nanni、Giuseppe Zanardi
    DOI:10.1016/s0040-4020(98)00230-0
    日期:1998.5
    New radical annulation reactions are described involving addition of cyano-substituted alkyl and sulfanyl radicals to aromatic isonitriles. The tandem cyclisation of the resulting imidoyl radicals onto the cyano group affords cyclopenta- and thienoquinoxalines, respectively. The intervention of the isonitriles in the aromatisation process of the cyclohexadienyl radicals is discussed, as well as the
    描述了新的自由基环化反应,该反应涉及将氰基取代的烷基和硫烷基基团加成到芳族异腈中。将所得的亚氨酰基自由基串联环合到氰基上,分别得到环戊达和噻吩并喹喔啉。讨论了异腈在环己二烯基的芳构化过程中的干预,以及通过将亚氨基加到腈部分而获得的亚胺基的环化的区域化学。半经验AM1计算的结果也支持了芳香环上只有6元闭环的假说。
  • Sulfur-mediated annulation of 1,2-phenylenediamines towards benzofuro- and benzothieno-quinoxalines

    Oxidation of sp3 C–H bonds in acetophenones is exploited to annulate with 1,2-phenylenediamines.

    在这个句子中,sp3 C-H键的氧化被利用来与1,2-苯二胺进行环化。
  • An umpolung strategy for rapid access to thermally activated delayed fluorescence (TADF) materials based on phenazine
    作者:Huaxing Zhang、Qiang Guo、Hu Cheng、Chunhao Ran、Di Wu、Jingbo Lan
    DOI:10.1039/d1cc06705b
    日期:——
    radical nucleophilic addition/rearrangement of 2-aryl diazaboroles has been accomplished for the first time to construct phenazine structures. This protocol is an umpolung strategy based on the classical electrophilic mechanism, and therefore, a reversed regioselectivity was observed, which provides an opportunity to prepare sterically hindered phenazines. The resulting thermally activated delayed fluorescence
    在此,Ag(I) 促进的 2-芳基二氮杂硼的区域选择性分子内自由基亲核加成/重排首次实现了构建吩嗪结构。该协议是一种基于经典亲电机制的 umpolung 策略,因此观察到了反向的区域选择性,这为制备空间位阻吩嗪提供了机会。由此产生的基于吩嗪的热激活延迟荧光 (TADF) 材料表现出从绿色到红色的发射带,具有高量子产率和中等荧光寿命作为固体薄膜。
  • α-(Arylthio)imidoyl Radicals:  [3 + 2] Radical Annulation of Aryl Isothiocyanates with 2-Cyano-Substituted Aryl Radicals
    作者:Rino Leardini、Daniele Nanni、Patrizia Pareschi、Antonio Tundo、Giuseppe Zanardi
    DOI:10.1021/jo971128a
    日期:1997.11.1
    A novel cascade radical reaction is described involving aryl isothiocyanates and 2-cyanoaryl radicals. The mechanism entails the formation of an alpha-(arylthio)imidoyl radical, a 5-exo-dig cyclization onto a cyano group, and a final 6-membered ring closure of an iminyl radical. The competitive 5-membered spiro-cyclization of the iminyl, leading to an isomeric product, was only observed in the case
    描述了涉及芳基异硫氰酸酯和2-氰基芳基的新型级联基反应。该机理需要形成α-(芳硫基)亚氨基基,在氰基上进行5-exo-dig环化反应,以及最终亚胺基的6-元闭环。仅在二取代的芳基异硫氰酸酯的情况下观察到亚胺基的竞争性5元螺环化,导致异构体产物。整个过程涉及一个罕见的[3 + 2]自由基环化的例子,并可以高产率单锅合成四缩氮杂环。
  • DABCO-Catalyzed DMSO-Promoted Sulfurative 1,2-Diamination of Phenylacetylenes with Elemental Sulfur and <i>o</i>-Phenylenediamines: Access to Quinoxaline-2-thiones
    作者:Thi Minh Chau Tran、Nang Duy Lai、Thai Thanh Thu Bui、Dinh Hung Mac、Thi Thu Tram Nguyen、Pascal Retailleau、Thanh Binh Nguyen
    DOI:10.1021/acs.orglett.3c02835
    日期:2023.10.6
    The oxidative amination of alkynes typically requires transition metal catalysts and strong oxidants. Herein, we alternatively utilize DABCO as a sulfur-activating catalyst to achieve the sulfurative 1,2-diamination of phenylacetylenes with elemental sulfur and o-phenylenediamines. DMSO was found to be particularly suitable for use as a terminal oxidant for this three-component process. A mechanistic
    炔烃的氧化胺化通常需要过渡金属催化剂和强氧化剂。在此,我们选择使用DABCO作为硫活化催化剂,实现苯乙炔与元素硫和邻苯二胺的硫化1,2-二胺化。人们发现 DMSO 特别适合用作这种三组分工艺的终端氧化剂。机理研究表明,这种级联反应是由活性硫物质添加到苯乙炔的三键上引发的。
