Single-atom iron-anchored graphitic C 3 N 5 for photocatalytic trifluoromethylation of aromatics and N-heterocycles in water

Anchoring single-atom Fe on g-C 3 N 5 creates a green, efficient strategy for aqueous trifluoromethylation. This recyclable photocatalyst synthesizes fluorinated compounds while avoiding toxic solvents and metal waste.
