Formation of Vinylic Dipyrroles by the Deprotonation of meso-Alkyl and meso-Benzyl Dipyrrin HCl Salts
摘要:
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.
