Starting from appropriately halogenated acylpyrroles, a wide range of reactive 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) derivatives can be obtained. The fluorescent dyes display excellent reactivity in nucleophilic aromatic substitution, transition-metal-catalyzed cross-coupling and copper-catalyzed cycloaddition to azides (click chemistry).
