## Abstract The syntheses of the five 2,2′: 6′,2″‐terpyridine (tpy) ligands 5–9 functionalized in the 4′‐position with a hydrazone substituent RR′CNNH (R=R′=Me; R=H, R′=4‐BrC~6~H~4~, 4‐O~2~NC~6~H~4~, 4‐MeOC~6~H~4~, or 3,5‐(MeO)~2~C~6~H~3~) are described. Protonation of the tpy domain of the ligan
## Abstract The well‐known reaction of 4′‐chloro‐2,2′:6′,2′′‐terpyridine with alkoxide nucleophiles leads to 4′‐functionalized 2,2′:6′,2′′‐terpyridines. This reaction allows the easy introduction of different functional groups onto the terpyridine at the 4′‐position, i.e. opposite to the metal bind
