Abstract
Tris(isonitrile)copper(I) complex salts with anions selected from BF.sub.4, PF.sub.6, ClO.sub.4, I, Br, Cl and CF.sub.3 COO are useful in preparing radionuclide complexes rapidly at room temperature. Preferred isonitrile ligands are ether isonitriles. The tris(isonitrile)copper(I) adducts enable technetium complexes, such as those of Tc99m, to be prepared easily just prior to their use as imaging agents.
