• A transition-metal-free Heck-type reaction between alkenes and alkyl iodides enabled by light in water
  作者：Wenbo Liu、Lu Li、Zhengwang Chen、Chao-Jun Li

  DOI：10.1039/c5ob00515a

  日期：——

  A transition-metal-free coupling protocol between various alkenes and non-activated alkyl iodides has been developed by using photoenergy in water for the first time. Under UV irradiation and basic aqueous conditions, various alkenes efficiently couple with a wide range of non-activated alkyl iodides. A tentative mechanism, which involves an atom transfer radical addition process, for the coupling

  triggers cooperative polar/radical pathways in a single catalytic cycle. This strategy has been applied to address a restricting limitation inherent to Cu-catalyzed B2pin2-carboboration of alkynes—the very low reactivity of the intermediate vinyl-Cu(I) species, which renders conventional methods ineffective with alkyl electrophiles other than simple primary halides. The crossover strategy enabled by

  我们描述了基于前所未有的动态多配体配位池的 Cu 催化的双重策略，该池在单个催化循环中触发合作的极性/自由基途径。该策略已被应用于解决 Cu 催化的 B 2 pin 2固有的限制性限制-炔烃的碳硼化——中间体乙烯基-Cu(I) 物质的反应性非常低，这使得传统方法对烷基亲电试剂无效，而不是简单的伯卤化物。通过有机金属中间体中的配体交换实现的交叉策略克服了这一反应性问题，将碳硼化的范围扩大到未活化的仲烷基卤化物，并开辟了获得立体定义的四取代乙烯基硼酸酯的新途径。该方法具有区域选择性和立体选择性，显示出优异的官能团耐受性，并允许在任一反应伙伴处掺入复杂的碳环和杂环片段。
• Photoinduced Palladium‐Catalyzed Dicarbofunctionalization of Terminal Alkynes
  作者：Zhen Yang、Rene M. Koenigs

  DOI：10.1002/chem.202005391

  日期：2021.2.19

  photochemical activation of palladium complexes enabled this strategic dicarbofunctionalization via addition of alkyl radicals from secondary and tertiary alkyl iodides and formation of an intermediate palladium vinyl complex that could undergo subsequent Sonogashira reaction with a second alkyne molecule. This alkylation–alkynylation sequence allowed the one‐step synthesis of 1,3‐enynes including heteroarenes

  在此，开发了一种概念上不同的方法，该方法允许使用简单的、工作台稳定的烷基碘和第二个炔烃分子作为偶联配偶体，在室温下对炔烃进行二碳官能化。具体来说，钯配合物的光化学活化通过从仲烷基碘化物和叔烷基碘化物中添加烷基自由基并形成中间体钯乙烯基配合物来实现这种战略性双碳官能化，该中间体钯乙烯基配合物可以与第二个炔分子进行后续的 Sonogashira 反应。这种烷基化-炔基化序列允许在不使用外源光敏剂或氧化剂的情况下高效地一步合成包括杂芳烃和生物活性化合物在内的1,3-烯炔，并且现在开辟了通过光化学钯催化进行级联反应的途径。
