As a variation of the commonly used bipy ligand in Re(CO) 3 chemistry, a series of structurally related complexes in which bipy is replaced by pyridine-triazole ligands (or pyta) bearing a pendant acetyl group on the triazole ring were prepared efficiently by the click chemistry approach. Depending on the nature of the pendant arm, different Re I complexes were obtained. Surprisingly, starting from the ligand with unprotected acetyl group yielded two structural isomers of Re(CO) 3 dimeric species. One isomer (compound 5a) was iso-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
