The present invention relates to chelators, in particular to chelators which are capable of forming complexes, i.e. paramagnetic chelates, with paramagnetic metal ions. The invention also relates to said paramagnetic chelates, said paramagnetic chelates linked to other molecules and their use as contrast agents in magnetic resonance imaging (MRI).

of 1,3,5,7-tetrabromoadamantane with cyanide produces 1,3,5,7-tetracyanoadamantane (1), which was reduced with borane reagents to 1,3,5,7-tetrakis(aminomethyl)adamantane (2). Improvements in the preparation of 1,3,5,7-tetrahaloadamantanes (halogen = Br, Cl, I) are also reported. [structure--see text]
