title: Synthesis and characterisation of the unsubstituted dipyrrin and 4,4-dichloro-4-bora-3a,4a-diaza-s-indacene: improved synthesis and functionalisation of the simplest BODIPY framework.
abstract: An improved and scalable synthesis of the unsubstituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene framework facilitates access to the previously unreported parent dipyrrin HCl salt, as well as 4,4-dichloro-4-bora-3a,4a-diaza-s-indacene.
