可见光促进的醇脱氧自由基杂芳基化是在没有任何外部光敏剂的情况下实现的。该过程是通过从醇生成黄原酸盐,然后进行 SET 和裂解,传递烷基自由基与杂芳基砜反应而发生的。该方法适用于多种醇,具有良好的官能团耐受性,为苯并杂芳烃的烷基化提供了实用的策略。机理研究表明,黄原酸阴离子的直接可见光激发和随后的 SET 引发反应。

Herein we present a Ni-catalyzed alkylation of C–SMe with alkyl bromides for the decoration of heterocyclic frameworks. The protocol, reminiscent to the Liebeskind–Srogl coupling, makes use of simple C(sp2)–SMe to be engaged in a reductive coupling. The reaction is suitable for a preponderance of highly valuable heterocyclic motifs. In addition to cyclic bromides, noncyclic alkyl bromides are well
在此,我们提出了用烷基溴对 C-SMe 进行 Ni 催化烷基化,用于装饰杂环骨架。该协议让人想起 Liebeskind-Srogl 耦合,利用简单的 C(sp2)-SMe 进行还原耦合。该反应适用于占优势的高价值杂环基序。除了环溴化物外,非环烷基溴化物也能很好地适应异构化的保留水平。该协议是可扩展的,并允许在存在其他功能化句柄的情况下进行正交耦合。
