Halogenated BODIPYs are important synthetic precursors and potential sensitizers for photodynamic therapy (PDT). Electrophilic bromination of pyrrolic-unsubstituted BODIPYs using bromine regioselectively generated mono- to heptabromoBODIPYs in a stepwise fashion in good to excellent yields. These resultant bromoBODIPYs were applied for regioselective substitution and Suzuki coupling reaction to generate

Copper catalysed vicarious nucleophilic substitution of 2-halogeno BODIPYs with alkyl amines, anilines and an amide produces the corresponding 3-aminoBODIPY derivatives.
