title: Formation of vinylic dipyrroles by the deprotonation of meso-alkyl and meso-benzyl dipyrrin HCl salts.
abstract: Under basic conditions, dipyrrin salts bearing alkyl and benzyl groups at the meso-position undergo deprotonation to give vinylic dipyrroles, rather than the corresponding free-base dipyrrins. The deprotonation is reversible and quantitatively returns the dipyrrinato framework under acidic conditions.
