Reactions of Pyrrole-2-carbaldehydes with Aromatic Di- and Tetraamines

2 Reactions of Pyrrole-2-carbaldehydes with Aromatic Di- and Tetraamines 

One-pot protocol for the synthesis of 2-(N-vinylpyrrol-2-yl)benzimidazoles requires air bubbling through a reaction mixture (DMSO, 70°C-80°C, 1 h). 

All of the 2-(N-vinylpyrrol-2-yl)benzimidazoles fluoresce intensely, including in practically important blue region of the spectrum 343-417 nm, Stokes shift 990-6880 cm-i).
