•A deep eutectic solvent ChCl/HFIP was prepared from choline chloride and hexafluoroisopropanol.•A rapid and environmentally friendly halogenation of BODIPYs in the deep eutectic solvent was achieved.•The deep eutectic solvent could be readily recovered and reused for several runs.
A deep eutectic solvent based on choline chloride and 1,1,1,3,3,3-hexafluoro-2-propanol was prepared. This deep eutectic solvent was used as the reaction medium for halogenation of boron dipyrromethene in the presence of N-halosuccinimide, which delivered the corresponding products in good to excellent yields (79–94%) in short reaction time (usually within 30 min). Moreover, this deep eutectic solvent could be easily prepared, recovered and reused for several runs without significant loss in the yields.
