• Radical C–H Arylation of Oxazoles with Aryl Iodides: dppf as an Electron-Transfer Mediator for Cs₂CO₃
  作者：Zhengwei Guo、Man Li、Xue-Qing Mou、Gang He、Xiao-Song Xue、Gong Chen

  日期：2018.3.16

  A radical C–H arylation reaction of oxazoles with (hetero)aryl iodides using Cs2CO3 as base/electron donor and 1,1′-bis(diphenylphosphino) ferrocene (dppf) as a catalytic SET mediator is reported. The overall reaction likely follows the general base-promoted homolytic aromatic substitution mechanism through a radical-chain pathway. DFT calculations suggest that dppf forms a complex with CsCO3–, enhancing

  报道了使用Cs 2 CO 3作为碱/电子给体和1,1'-双（二苯基膦基）二茂铁（dppf）作为催化SET介体，恶唑与（杂）芳基碘化物的自由基CH芳基化反应。整个反应可能通过自由基链途径遵循一般的碱促进的均质芳族取代机理。DFT计算表明，dppf与CsCO 3 –形成络合物，增强了SET还原能力，可从ArI生成芳基。
