Additional NMR Data on Compounds of the Type cis-Ti(AA)2X2
Journal of Fluroine Chemistry
Previous work has shown that cis-disubstituted (acac)2 titanium (IV) complexes exist in solution as nonrigid molecules . These studies were followed by variable temperature 1H NMR spectroscopy. The spectra shows that for the dialkoxy and dihalo complexes the acetylacetonate (acac) rings exchange the methyl groups between the two nonequivalent sites of the cis isomer. These rearrangements take place via an intramolecular rearrangement: both twisting and one bond rupture mechanisms have been suggested for these stero-chemical rearrangements [2-4].
