Synthesis, structural and thermal characterisation of titanium silylamido complexes

The titanium silylamido complexes [{R2Si(NtBu)2}2Ti] (R = Me (3) and R = Ph (4)), [{(R2Si(NtBu)2)Ti(μ2-NtBu)}2] (R = Me (5) and R = Ph (6) have been synthesised from the reaction of the lithio-silylamide ligands [{R2Si(NtBu)2}Li2] (R = Me; (1), R = Ph; (2)) with TiCl4 and [Ti(NtBu)Cl2(Py)2] respectively. In the case of complexes 2, 3 and 5 the complexes have been structurally characterised by single crystal X-ray diffraction. The thermal profiles of the four silylamido (3–6) complexes have also been investigated by thermogravimetric analysis.
