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.
