  气态氨气的电化学加氢

  摘要：

  氨作为无碳且可持续的燃料，是高能量密度的储氢材料。开发能够直接利用氨作为氢源的新反应非常重要。在这里，我们报告了使用氨作为氢源和碳电极对烯烃，炔烃和酮进行电化学加氢。很好地耐受各种杂环和官能团，包括例如硫化物，苄基，氨基甲酸苄基酯和氨基甲酸烯丙酯。提出了快速的逐步电子转移和质子转移过程来解释这种转变。

• Organocatalytic decarboxylative alkylation of <i>N</i>-hydroxy-phthalimide esters enabled by pyridine-boryl radicals

  The decarboxylative alkylation of N-hydroxyphthalimide (NHPI) based reactive esters with olefins has been achieved via an organocatalytic strategy. Control experiments and density functional theory calculations suggest that these reactions involve a boryl-radical mediated decarboxylation pathway, which is different from the single electron transfer involved in decarboxylative alkylation reactions reported

  N-羟基邻苯二甲酰亚胺（NHPI）基反应性酯与烯烃的脱羧烷基化已通过有机催化策略实现。对照实验和密度泛函理论计算表明，这些反应涉及硼基自由基介导的脱羧途径，该途径不同于先前报道的脱羧烷基化反应中涉及的单电子转移。这种无金属的脱羧烷基化反应具有良好的功能相容性，并且通过烷基和芳基羧酸衍生物的转化说明了广泛的底物范围。

  palladium complex catalyzes the title transformations, which are thought to proceed via a π‐allyl or π‐benzyl intermediate. The regioselectivity of the reaction (1,2‐ or 1,1‐difunctionalization) depends on the type of terminal double bond (conjugated or nonconjugated) in the substrate (see scheme) and appears to be controlled by the relative rates of β‐hydride elimination and transmetalation. DMA=dimethylacetamide

  Triarylsulfonium salts are prompted to undergo efficient homolytic reduction by single electron transfer under mild photocatalytic conditions. The liberated aryl radical can then participate in carbon‐carbon bond formation processes with allyl sulfones and activated olefins. Triarylsulfonium salts emerge as a valuable and alternative source of aryl radicals for synthesis.

  三芳基ulf盐在温和的光催化条件下通过单电子转移被提示进行有效的均相还原。释放的芳基然后可以与烯丙基砜和活性烯烃一起参与碳-碳键的形成过程。三芳基ulf盐作为合成芳基的有价值和替代来源而出现。
• Transition‐Metal‐Free Intermolecular Hydrocarbonation of Styrenes Mediated by NaH/1,10‐Phenanthroline

  AbstractA transition‐metal‐free intermolecular coupling reaction of halocompounds with styrenes in the presence of NaH and 1,10‐phenanthroline was developed. This reaction afforded hydrocarbonated products with complete anti‐Markovnikov selectivity. The method allows the use of a wide range of halocompounds, including aryl and alkyl halides, and good functional group tolerance. Detailed mechanistic studies indicated that an anilide anion generated in situ by the NaH‐mediated reduction of 1,10‐phenanthroline works as an electron donor and a hydrogen source.
