✦ Synopsis

The synthesis of trinuclear open-chain prototypes gave variable yields: Ͼ 53% for dications 1•2X and 2•2X and Ͼ 80% for proton-ionizable dications 3•2X-5•2X incorporating 1H-1,2,4-triazole moieties. Deprotonation of the latter compounds resulted in the formation of the betaine counterparts 13•X-15•X. The courses of the dequaternization reactions of compounds 4•2X and 5•2X were also studied. The structural properties of dicationic protophanes 1•2X and 2•2X, containing bis(imidazolium) motifs, were examined by 1 H and [ ‡] Heterocyclic Betaines, 47. Ϫ Part 46: Ref. [1a] [a]
