The pyrrolyl substituent enhances the electron densities on the pyridazine ring and has the effect of shifting the positions of the tautomeric equilibria for 1c,d 2c,d, which exist predominantly as the pyridazin-3-one and -3-thione forms, towards the

3,6-Dichloropyridazine and 1-alkyl-3,6-dichloropyridazinium cations react with pyrrolylmagnesium bromide to produce 3-chloro-6-(2-pyrrolyl)pyridazine. Further reaction with other nucleophiles is slow, but is enhanced by quaternisation of the 2-N atom

The Stetter procedure has been adapted to produce oligomeric and polymeric pyrrolylpyridines, which have been characterised by 13 C NMR spectroscopy. The lower activity of 2-(pyrrol-2-yl)pyridines towards quaternisation permits selective N-alkylation
