S. Elshani et al., NEW PROTON-IONIZABLE MACROCYCLIC-COMPOUNDS CONTAINING ONE AND 2 TRIAZOLE SUBCYCLIC UNITS - SYNTHESIS AND COMPLEXATION PROPERTIES, Journal of heterocyclic chemistry, 31(5), 1994, pp. 1271-1274
A series of new macrocyclic compounds containing one and two proton-io
nizable triazole subcyclic units have been prepared and characterized.
These triazolo-crowns containing benzo, tert-butylbenzo or cyclohexan
o lipophilic groups show varying solubilities in chloroform. The bistr
iazolo-crowns dissolved in chloroform are highly effective for extract
ion of lead, mercury, and gold from aqueous solutions.
