Abstract

Abstract The synthesis of trinuclear open-chain prototypes gave variable yields:> 53% for dications 1· 2X and 2· 2X and> 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 ...
