“…In fact, 1,4-functionalized 1,2,3-triazoles are potentially versatile ligands offering several donor sites for metal coordination and have been extensively applied to the preparation of potential 99m Tc radiopharmaceuticals [ 8 , 9 , 10 ]. Our group has utilized this method for the synthesis of glucose, nitroimidazole, flutamide, and estradiol derivatives for technetium labeling ( Figure 1 ) [ 11 , 12 , 13 , 14 , 15 , 16 ].…”
