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)3(X m)3](1+3m), 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-(C2B9H11)]2- and functional derivatives thereof. The method has been shown to be applicable to the preparation of radiopharmaceuticals at the tracer level.
