Thus treatment of 1a with Na2[substituted-salen] gave monomeric [Ti(NBut)(substituted-salen)] where substituted-salen = Et2salen (2) or But4salen (4). In contrast, the binuclear complex [Ti(NBut){μ-(MeO)2salen}]2 (5) was obtained from 1a and Na2[(MeO)2salen]. The less sterically crowded compounds 2 and 5 undergo tert-butyl imide/arylamine exchange reactions to form [Ti(N-2,6-C6H3Me2)(Et2salen)] (3) and [Ti(N-2,6-C6H3Me2){μ-(MeO)2salen}]2 (6), respectively, whereas 4 does not exhibit this kind of reactivity. The compound 3 can also be obtained directly from Na2[Et2salen] and [Ti(N-2,6-C6H3Me2)Cl2(py)3] (1b).
