Treatment of the titanium(iv) alkoxide complex [Ti(OiPr)(OC 6Me2H2CH2)3N] (2) with BH3·THF, as part of a study into the utility and reactivity of (2) in the metal mediated borane reduction of acetophenone, results in alkoxide-hydride exchange and formation of the structurally characterised titanium(iv) tetrahydroborate complex [Ti{BH4}(OC6Me 2H2CH2)3N] (3). Complex (3) readily undergoes reduction to form the isolable titanium(iii) species [Ti(OC 6Me2H2CH2)3N] 2 (4). Reaction of (2) with B(C6F5)3 results in formation of the Lewis acid adduct [Ti(OC6Me 2H2CH2)3N][HO·B(C 6F5)3] (5). In comparison, treatment of the less sterically encumbered alkoxide Ti(OiPr)4 with B(C6F5)3 results in alkoxide-aryl exchange and formation of the organometallic titanium complex [Ti(OiPr) 3(C6F5)]2 (6). The molecular structures of 3, 4, 5 and 6 have been determined by X-ray diffraction. The Royal Society of Chemistry.
