Vitamin B12 as a Ligand for Technetium and Rhenium Complexes

Abstract

Robust complexes with a central {Co-CN-Re(Tc)} feature are formed when the cyanide ligand in vitamin B12 acts as bridging ligand between rhenium and technetium carbonyl complexes (see picture). This concept paves the way for radiolabeling of vitamin B12 or metal-mediated coupling of bioactive molecules.
