, is reduced by thionyl chloride and phosphoryl chloride, respectively, to yield semistable Tc(VI) intermediates which can easily be detected by EPR spectroscopy. Spectra are recorded in liquid and frozen solutions. EPR data as well as chemical behaviour suggest the compounds obtained to be oxochloro complexes of technetium(VI).

A series of technetium complexes with different alkyl dithiocarbamates, dithiophosphates and xanthates has been prepared at tracer level (10–4 molar) starting from hydrazine-reduced pertechnetate and Tc(V) gluconate, respectively. Solution studies show the complexes to be neutral, lipid-soluble tracers. Their in vitro properties can be varied in a wide range by variation of alkyl substitution of the ligands.
