• Regioselective Iron‐Catalysed Cross‐Coupling Reaction of Aryl Propargylic Bromides and Aryl Grignard Reagents

  An iron‐catalysed Kumada‐type cross‐coupling reaction between aryl substituted propargylic bromides and arylmagnesium reagents has been developed. Propargylic coupling products were the main or only outcome, and propargyl/allene regioselectivity was shown to depend on the electronic nature of the substituents on the triple bond of the substrate and on the arylmagnesium halide. Best selectivities were

  芳基取代的炔丙基溴化物与芳基镁试剂之间的铁催化的Kumada型交叉偶联反应已得到开发。炔丙基偶联产物是主要或唯一的产物，炔丙基/丙二烯的区域选择性显示出取决于底物三键和芳基卤化镁上取代基的电子性质。当两种试剂中都存在供电子取代基时，观察到最佳选择性。该过程是立体的，发生构型反转，并且似乎没有碳基自由基参与该机理。

  The synthesis of regio- and stereoselective aryl substituted α,β-unsaturated aldehydes and ketones from activated allenes was achieved. This mild and non-metallic oxidation is exclusively driven by benign ambient air and triggered by visible light. The same starting materials under ideal anaerobic conditions led to the 2,3-diphenylselenation adduct with no trace of oxygenated products, demonstrating

  regioselective radical diacylation of allenes with ketoacids to produce 1,4-dione products by dual photoredox and nickel catalysis. This integrated approach merges redox-active oxidative addition and reductive elimination steps with migratory insertion. The acyl radical generated in the photoredox cycle sequentially adds to Ni(I) and Ni(II) intermediates following a Ni(I)–Ni(II)–Ni(II)–Ni(III)–Ni(I) catalytic

  我们提出了一种镍催化的丙二烯与酮酸的区域选择性自由基二酰化反应，通过双重光氧化还原和镍催化生产 1,4-二酮产品。这种集成方法将氧化还原活性氧化加成和还原消除步骤与迁移插入结合起来。光氧化还原循环中产生的酰基自由基在 Ni(I)–Ni(II)–Ni(II)–Ni(III)–Ni(I) 催化循环后依次添加到 Ni(I) 和 Ni(II) 中间体。这种由 DFT 计算支持的方法证明了镍催化在创建复杂分子结构方面的潜力。
• Synthesis of Terminal Allenes through Copper-Mediated Cross-Coupling of Ethyne with<i>N</i>-Tosylhydrazones or α-Diazoesters

  Ethyne is employed as coupling partner in copper-mediated cross-coupling reactions with N-tosylhydrazones and alpha-diazoacetate, leading to the development of a new synthetic method for terminal allenes. With this novel coupling method, the terminal allenes were obtained in good yields and with excellent functional group tolerance. Copper carbene migratory insertion is proposed as the key step in these transformations.
• Lewis Acid Promoted Reactions of Ethenetricarboxylates with Allenes: Synthesis of Indenes and γ-Lactones via Conjugate Addition/Cyclization Reaction

  Indenes are important core structures in organic chemistry. Few simple arylallenes have been used to construct indene skeletons by Friedel Crafts reaction. Lewis acid catalyzed reaction of ethenetricarboxylates 1 and arylallenes has been examined in this study. The reaction of arylallenes and ethenetricarboxylate triesters with SnCl4 gave indene derivatives efficiently, via a conjugate addition/Friedel-Crafts cyclization reaction. On the other hand, the reactions of 1,1-diethyl 2-hydrogen ethenetricarboxylate and arylallenes or alkylallenes with SnCl4 at -78 degrees C or room temperature and subsequent treatment with Et3N gave gamma-lactones. The reactions of triethyl ethenetricarboxylate and 1,1-dialkylallenes with SnCl4 at room temperature also gave gamma-lactones.
