11. 3; however, this would not explain the formation of the chloro over the alkoxy complex, since chloro ligands are present in both rhenium starting materials.
12. A satisfactory elemental analysis could not be obtained of all complexes, although they had been characterized using NMR, TLC, and in one case even X-ray crystallography.
13. There are no significant differences in the overall conformation of the ReO(salbd) moieties of 2c,d.

16. 6 postulated that the nonsymmetrical configuration is thermodynamically more stable.
17. NMR experiments in which the symmetrical methoxy complex was heated (60 °C) in 1,1,2,2-tetrachloroethane to induce the rearrangement resulted in precipitation of the μ-oxo complex.
