Rhenium(i) tricarbonyl complexes of a range of bidentate, bis-bidentate and tridentate NHC ligands have been prepared. These NHC ligands are of interest for possible applications in the development of Tc-99m or Re-186/188 radiopharmaceuticals and the stability of two complexes were evaluated in ligand challenge experiments using the metal binding amino acids l-histidine or l-cysteine.
铼(i)三羰基配合物已经制备了一系列双齿、双双齿和三齿NHC配体。这些NHC配体可能在Tc-99m或Re-186/188放射性药物的开发中应用,通过使用金属结合氨基酸l-组氨酸或l-半胱氨酸进行配体挑战实验评估了两种配合物的稳定性。
