Efficient new synthetic routes to trans-O-2Repy-X2py-Y2 and cis-O2Rebpy-Y2py-X2 complexes have been devised py is pyridine bpy is 2,2-bipyridine. The new routes make use of labile cis-O2Repy-X2I 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.
