  摘要：

  AbstractA mild and efficient silver‐catalyzed acylarylation of activated alkenes with easily available α‐oxocarboxylic acids has been developed. The reactions provide a rapid access to a variety of functionalized oxindoles via a tandem decarboxylative radical cyclization strategy. This transformation proceeds well under mild reaction conditions and exhibits excellent functional group tolerance, affording the desired oxindoles in good to excellent yields.magnified image

  A novel method for the mild photoredox‐mediated tandem radical acylarylation and tandem acylation/semipinacol rearrangement has been developed. The synthesis of highly functionalized ketones bearing all‐carbon α‐ or β‐quaternary centers has been achieved using easily available symmetric aromatic carboxylic anhydrides as the acyl radical source. The method allows for a straightforward introduction of

  Simple and abundant carboxylic acids have been used as acyl radical precursor by means of visible‐light photoredox catalysis. By the transient generation of a reactive anhydride intermediate, this redox‐neutral approach offers a mild and rapid entry to high‐value heterocyclic compounds without the need of UV irradiation, high temperature, high CO pressure, tin reagents, or peroxides.

  We herein describe a simple approach for generating acyl radical from acyl chloride via photoinduced single-electron transfer. It has been demonstrated that the generated acyl radicals could react with various substrates, including isocyanides, methacrylamides, alkenes, alkynes, and enynes, to afford diverse heterocycles (>10 classes). Mechanistic analyses show that a photoactive charge transfer complex

  我们在此描述了一种通过光诱导单电子转移从酰氯产生酰基自由基的简单方法。已经证明，产生的酰基自由基可以与各种底物反应，包括异氰化物、甲基丙烯酰胺、烯烃、炔烃和烯炔，以提供多种杂环（> 10 类）。机理分析表明，酰氯和路易斯碱添加剂之间的光活性电荷转移络合物参与了酰基自由基的光生成。该研究举例说明了一种新的简单的羰基化合物光活化方法。
