4′-(<i>N</i>-(Propargyl)pyrrol-2-yl)-2,2′:6′,2′′-terpyridine

Abstract

A new terpyridine molecule, bearing a N-propargylated pyrrole, was prepared and characterized. Its synthesis was based on a Krohnke-type reaction between 2-acetylpyridine and N-propargylpyrrole-2-carboxaldehyde in a basic medium. An allene-containing terpyridine was also obtained as a by-product.
