  • Controlled Reactivity of 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) in the Selective Synthesis of 1-(Bromoethynyl)arenes

    1‐(bromoethynyl)arenes from 1,1‐dibromoalkenes. Differential reactivity of DBU in protic solvents as compared to aprotic solvents has been explored to prevent the formation of mixtures of products in this reaction. Hydrated DBU is found to be superior to dry DBU, both for the selective synthesis and ease of isolation. In addition, use of DBU⋅H2O as a non‐nucleophilic mild base allowed us to synthesise 1‐

    one pyrene ring functions as an acceptor via a common Y-shaped ‘enediyne’ bridge which facilitates the cross-electronic communication. The dye exhibits dual emission from locally excited (LE) and intramolecular charge transfer (ICT) states. While the LE emission is dominant in non-polar solvents, the ICT emission predominates in polar solvents. Time-resolved fluorescence decay experiments reveal a relatively
    推挽式有机荧光团因其有趣的光电特性而非常重要。在这里,我们报告了一种新的交叉共轭推挽双烯炔染料的光物理性质,该染料属于未探索的π共轭供体-受体体系。两个N,N-二甲基苯胺部分用作供体,一个pyr环通过常见的Y形“二烯”桥,促进了跨电子通信。该染料表现出局部激发(LE)和分子内电荷转移(ICT)状态的双重发射。尽管LE发射在非极性溶剂中占主导地位,但ICT发射在极性溶剂中占主导地位。时间分辨的荧光衰减实验表明,属于ICT状态的寿命相对较短(约0.5-0.9 ns),与LE状态相对应的寿命较长(约1.6-2.8 ns)。染料的强ICT行为通过发射光谱从非极性环己烷到极性N,N的巨大红移(4166 cm -1)得以体现。-二甲基甲酰胺。与许多小的推挽有机染料相反,推挽双炔炔染料的LE和ICT状态遵循相同的激发途径。长时间暴露于光子中,染料在极性溶剂中的主要红移ICT发射强度(约550 nm)随着蓝移LE发射(约385

  • The Dual Role of 1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) in the Synthesis of Terminal Aryl- and Styryl-Acetylenes via Umpolung Reactivity
    作者:Ashok Kumar Morri、Yadagiri Thummala、Venkata Ramana Doddi
    DOI:10.1021/acs.orglett.5b02398
    日期:2015.9.18
    The dual role of the bicyclic amidine base 1,8-diazabicydo[5.4.0]undec-7-ene (DBU) was demonstrated in a synthesis of terminal aryl- and styryl-acetylenes. Mechanistically, a tandem process involving elimination/Umpolung/protonation occurs in a single step to generate terminal aryland styryl-acetylenes from geminal dibromoalkenes. The key to the success of this transformation lies in the organobase-mediated generation of the acetylide from the 1-bromoalkynes at room temperature. The unique characteristics of DBU as an inherently safer reagent make it an attractive alternative to previous systems wherein required pyrophoric reagents and nonambient temperatures remain unsolved issues. The procedure does not work for the synthesis of alkyl-acetylenes.
