  Cycloaddition Reactions of the Titanium Imide [Ti(NBu^t){MeC(2-C₅H₄N)(CH₂NSiMe₃)₂}(py)] with Bu^tCP and MeCN

  摘要：

  The diamidopyridine-supported titanium imide [Ti(NBut)(L)(py)] [1, L = MeC(2-C5H4N)(CH2-NSiMe3)(2)] undergoes a [2+2] cycloaddition reaction with (BuCP)-C-t to form the mononuclear product [Ti{N(Bu-t)PC(Bu-t)}(L)] (2). In contrast, reaction of 1 with MeCN affords the binuclear derivative [Ti-2{mu-eta(2)-NC(Me)NBut}(2)(L)(2)] (3), which contains a doubly deprotonated N-tert-butylacetamidinate ligand. Compound 3 undergoes a quantitative cycloreversion reaction at elevated temperatures yielding MeCN and [Ti(NBut)(L)] (4).

  Reaction of the lithium amides [(2-C5H4N)C(CH3)CH2N(Li)SiMe3}(2)](2) (2a) and [(2-C5H4N)C(CH3)CH2N(Li)-SiMe(2)tBu}(2)](2) (2b) with the imidotransition metal complexes [Ti(NtBu)Cl-2(py)(3)], [Ti(N-2,6-C(6)H(3)iPr(2))Cl-2(py)(3)], and [Zr(N-2,6-C(6)H(3)iPr(2))Cl-2(thf)(2)] yielded the five-coordinate imido-titanium and -zirconium complexes [kappa N-3-(2-C5H4N)C(CH3)(CH2NSiMe2R)(2)}Ti(NR')(py)] (R = Me, R' = tBu: 3a, R = tBu, R' = tBu: 3b, R = Me, R' = 2,6-C(6)H(3)iPr(2): 4a, R = Me, R' = 2,6-C6H3Me2: 4b) and [(kappa N-3-(2-C5H4N)C(CH3)(CH2NSiMe3)(2)}Zr(N-2,6-C(6)H(3)iPr(2))(py)] (5). The tridentate diamido-pyridine ligand adopts a facial coordination mode in the distorted trigonal bipyramidal complexes with the imido ligand occupying an equatorial position, as was established by X-ray diffraction for 3a and 5. Sublimation of 3a and 4a yielded the pure four-coordinate imidotitanium complexes [kappa N-3-(2-C5H4N)C(CH3)(CH2NSiMe3)(2)}Ti(NR')] (R' = tBu: 6, 2,6-C(6)H(3)iPr(2): 7) which were structurally characterized by X-ray crystallography. Reaction of 3a with the Lewis acid B(C6F5)(3) also led to abstraction of the axially bound pyridine ligand and the formation of the adduct [py-B(C6F5)(3)] and 6. Reaction of 6 with thf, PMe3, and pyridine led to the formation of pentacoordinate complexes [kappa N-3-(2-C5H4N)C(CH3)(CH2NSiMe3)(2)}-Ti(NtBu)(thf)] (8), [kappa N-3-(2-C5H4N)C(CH3)(CH2NSiMe3)(2)}Ti(NtBu)(PMe3)] (9), and [kappa N-3-(2-C5H4N)C(CH3)(CH2-NSiMe3)(2)}Ti(NtBu)(py)] (3a) in which the donor ligands occupy axial positions.
