Efficient new synthetic routes to trans-(O)2Re(py-X)2(py-Y)2+ and cis-(O)2Re(bpy-Y2)(py-X)2+ complexes have been devised (py = pyridine; bpy = 2,2′-biρyridine). The new routes make use of labile cis-(O)2Re(py-X)2(I) species as preparative intermediates. The most useful new features of the synthetic chemistry are (1) the ability to prepare trans species containing electron-withdrawing substituents, (2) the ability to prepare mixed-ligand trans-dioxorhenium species, and (3) generalization of the cis-dioxorhenium preparation.
