One-Pot Efficient Synthesis of 1,4-Bis (2,2′:6′,2′′-Terpyridin-4′-Yl) Benzene Ditopic Bridging Ligand

One-Pot Efficient Synthesis of 1,4-Bis (2,2′:6′,2′′-Terpyridin-4′-Yl) Benzene Ditopic Bridging Ligand. Abstract The ditopic bridging 1,4-bis(2,2′:6′,2′′-terpyridin-4′-yl) benzene (I) was prepared in a controlled one-pot condensation reaction of acetylpyri - dine, benzene-1,4-dicarbaldehyde and ammonium acetate in basic medium in EtOH in high yield. The product was characterised using conventional methods.
