Abstract
The present invention relates to a new method for the preparation of radiopharmaceuticals based on technetium and rhenium. The method involves the reaction of a salt of the formula [M(CO)(X)], wherein M is selected from a radioisotope of rhenium, technetium and any other radioisotope that binds in a similar fashion, X is any suitable ligand and m is the formal charge for ligand X, with a nido-dicarbollide dianion of the formula [nido-(CBH)]and functional derivatives thereof. The method has been shown to be applicable to the preparation of radiopharmaceuticals at the tracer level.
