The preparation and characterization of a new terpyridine molecule containing an acetylenic moiety is described. Part this molecule, unknown in the literature, obtained from biomass-derived synthon that formed naturally occurring syringaldehyde 4-hydroxy-3,5-dimethoxybenzaldehyde. title compound was fully characterized by NMR spectroscopy (1H 13C), as well high-resolution mass spectrometry infr...
