Low-nuclearity titanium alkoxides and their rhodium derivatives

The reaction of Ti(OPri)4 with 0.078 equiv. of 10 atom% 17O enriched water and 0.6 equiv. of MeOH in i-PrOH solution gave [Ti3O](OPr i)9(OMe) (1). A single crystal X-ray diffraction study of this material indicated that 1 contains two crystallographically-independent Ti3(mu3-O)(mu3-OMe)(mu2-OPr i)3(OPri)6 molecules. The analogous molecule [Ti3O[(OPri)10 (1a) was generated in solution by hydrolysis of Ti(OPri)4 with 0.02 equiv. of water in i-PrOH, and identified using 17O, 13C{1H}, and 1H NMR techniques. Variable temperature NMR spectroscopic studies show that 1 retains its solid state structure at low temperature. It decomposes quickly at room temperature, however, to form Ti(OMe)x(OPr i)4-x, and other polyoxotitanates. 1 has the lowest stability toward parent alcohol and inert hydrocarbon solvents among all known titanium polyoxoalkoxides.
