Tc(VII) and Re(VII) trioxo complexes are currently arousing interest because of their potential use as radiopharmaceuticals due to their hydrophilic character and stability in a biological environment. The radioactive isotopes 99mTc and 188Re are readily obtained from commercially available 99Mo/99mTc or 188W/188Re generators, respectively. Stabilization of the [MO3]+ species is achieved by coordination of tridentate ligands (N, O, S and Pt donors). Herein, the various synthetic strategies to synthesize these complexes starting from M2O7, [MO4]−, M(+V), M(+III) or M(+I) species are revised. The main structural features of the obtained distorted octahedral metal compounds are presented on the basis of their characterization by NMR and IR spectroscopy, and X-ray crystallography. Interestingly, the [MO3]+ complexes undergo cycloaddition reactions, either to form the corresponding M(+V) diolate complexes via [3 + 2] cycloaddition, or carbene complexes via [2 + 2] cycloaddition. In this review we also comment on the few reported examples using [3 + 2] cycloaddition to label the trioxo compounds with bioactive molecules for their potential application as radiopharmaceuticals.
