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

Abstract

The preparation and characterization of a new multi-functionalized terpyridine molecule featuring a pyrrole heterocycle and a cyano group is described. This new compound was obtained via a KF/alumina-catalyzed Michael addition of 4′-(pyrrol-2-yl)-2,2′:6′,2″-terpyridine into acrylonitrile. The mild reaction conditions leave the nitrile group unaltered. The title compound was fully characterized via NMR spectroscopy (1H and 13C) as well as via high resolution mass spectrometry and infrared spectroscopy.
