INOR 169 |
| Transition metal compounds with low coordination numbers often exhibit interesting structural and chemical properties. The bulky and little studied di(tert-butyl)amide ligand is well suited for making compounds that exhibit such properties. Treatment of TiCl4 with HN(t-Bu)2 affords the chloride-bridged dimer Ti2Cl6[N(t-Bu)2]2; each five-coordinate titanium atom is involved with one close Ti∙∙∙C contact of 2.63 Å with a g-carbon atom. Treatment of TiCl4 with LiN(t-Bu)2 affords the imide-bridged dimer Ti2Cl2[N(t-Bu)]2[N(t-Bu)2]2, in which the bridging imide group appears to be the result of dealkylation of the di(tert-butyl)amide ligand. Variable temperature NMR studies reveal that rotation about the Ti-N bonds is slow on the NMR time scale at low temperature. The nature of the agnostic interactions will be discussed.
