摘要 |
The present invention relates to a method of preparing metal-carborane complexes comprising reacting a salt of the formula: [M(CO)3(X m)3](1 + 3m), wherein M is selected from a radioisotope of rhenium (Re), technetium (Tc) and any other radioisotope binding in the same fashion, X is the same of different and is, independently, any suitable ligand and m is the formal charge for ligand X, with a nido-dicarbollide dianion in the presence of a hard bas e. In an embodiment of the invention, the hard base is a source of fluorid e.
