  The room-temperature oxidative C–H/C–H cross-couplings between simple arenes and alkenes, coumarins or quinones have been reported by using a highly electrophilic palladium species [Pd(TFA)₂] as the catalyst and cheap (NH₄)₂S₂O₈ as the oxidant under air.

  regioselectivity. Often, the high thermal energy required to promote olefination leads to multiple site functionalizations. To this aim, we established a photoredox catalytic system constituting a merger of palladium/organo-photocatalyst (PC) that forges oxidative olefination in an explicit regioselective fashion with diverse arenes and heteroarenes. Visible light plays a significant role in executing “regioresolved”

  藤原-森谷反应对当代 C-H 激活方案的出现做出了深远的贡献。尽管传统方法在不同领域具有适用性，但相关的反应性和区域选择性问题使其变得多余。该示例性反应的复兴需要开发一种机械范式，该范式将同时控制反应性和区域选择性。通常，促进烯烃化所需的高热能导致多位点官能化。为此，我们建立了一个光氧化还原催化系统，该系统由钯/有机光催化剂 (PC) 的合并组成，该系统以显式的区域选择性方式与多种芳烃和杂芳烃进行氧化烯化。可见光在不需要银盐和热能的情况下在执行“区域分解”的藤原-森谷反应中起着重要作用。该催化系统还可以在各自的导向基团 (DGs) 的帮助下进行近端和远端烯烃化，这需要该协议在参与整个 C(sp) 光谱方面的多功能性2 )-H烯化。此外，通过后期功能化简化天然产物、手性分子、药物的合成和多样化，强调了这种可持续协议的重要性。这种区域选择性转化的光诱导实现是通过控制反应和动力学研究机械地建立的。
