An efficient, mild and photo redox‐based protocol for the C–H trifluoromethylation of imidazo[1,2‐a]pyridines has been developed using acridinium as photo redox catalyst and the easy‐handling CF₃SO₂Na as CF₃ source. A series of desired products were afforded in satisfied yields under transition‐metal‐free condition, which displays potential for further application in synthetic research.

咪唑并吡啶的可见光促进无金属C-H三氟甲基化

已经开发了一种高效，温和且基于光氧化还原的协议，该方法使用cri啶作为光氧化还原催化剂，并使用易于处理的CF ₃ SO ₂ Na作为CF ₃来源，开发了咪唑并[1,2- a ]吡啶的CHH三氟甲基化反应。在无过渡金属的条件下，以令人满意的产率提供了一系列所需的产品，这显示了在合成研究中进一步应用的潜力。
