The reactivity of the imido−nitrido trinuclear complex [{Ti(η5-C5Me5)(μ-NH)}3(μ3-N)] (1) toward alkyl derivatives of group 13 and 14 elements has been investigated. Treatment of 1 with trialkyl derivatives of aluminum, gallium, or indium at room temperature afforded the adducts [R3M{(μ3-NH)3Ti3(η5-C5Me5)3(μ3-N)}] (R = CH2SiMe3, M = Al (3), Ga (4), In (5); R = CH2C6H5, M = Ga (6), In (7)). The analogous reaction of 1 with [AlMe3] at 90 °C gave the methylaluminum derivative [MeAl{(μ3-N)2(μ3-NH)Ti3(η5-C5Me5)3(μ3-N)}] (8) via methane elimination. Complexes 3 and 6 at this temperature gave also monoalkyl complexes [RM{(μ3-N)2(μ3-NH)Ti3(η5-C5Me5)3(μ3-N)}] (M = Al, R = CH2SiMe3 (9); M = Ga, R = CH2C6H5 (11)), whereas the indium derivative 7 led to the indium(I) complex [In{(μ3-N)(μ3-NH)2Ti3(η5-C5Me5)3(μ3-N)}] (12) and bibenzyl. Analogous chloromethylaluminum adducts [Me n Cl3- n Al{(μ3-NH)3Ti3(η5-C5Me5)3(μ3-N)}] (n = 1 (13), 2 (14)) were obtained by treatment of 1 with [AlCl3- n Me n ]. Reaction of the lithium reagent [Li(μ4-N)(μ3-NH)2{Ti3(η5-C5Me5)3(μ3-N)}]2 with tin, germanium, and silicon chloroalkyl derivatives [MClMe3] gave the group 14 alkyl complexes [Me3M{(μ3-N)Ti3(η5-C5Me5)3(μ-NH)2(μ3-N)}] (M = Sn (15), Ge (16), Si (17)). The X-ray crystal structures of 6, 7, 9, 13, 15, and 16 have been determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
