Titanium Imido Complexes with Tetradentate Schiff Base Ligands

Inorganic Chemistry, 1998
New mono- and binuclear titanium imido complexes supported by tetradentate, dianionic N(2)O(2)-donor Schiff base ligands were prepared in good yield from the readily available [Ti(NBu(t))Cl(2)(py)(3)] (1a). Thus treatment of 1a with Na(2)[substituted-salen] gave monomeric [Ti(NBu(t))(substituted-salen)] where substituted-salen = Et(2)salen (2) or Bu(t)(
