    class of titanium precatalysts of the type (ONO)TiX2 (ONO = pyridine-2,6-bis(4,6-di-tert-butylphenolate); X = Bn, NMe2) has been synthesized and crystallographically characterized. The (ONO)TiX2 (X = Bn, NMe2, X2 = NPh) complexes are highly active precatalysts for the hydroamination of internal alkynes with primary arylamines and some alkylamines.

    The multi-gram scale syntheses of the first 1,3,5-triazacyclohexane imido complexes [Ti(NR)(R3′tach)Cl2] (R=But, C6H3Pr2i-2,6; R′=Me, But) are described together with the X-ray structures of [Ti(NBut)(Me3tach)Cl2] and [Ti(NBut)(Bu3ttach)Cl2]; the complexes of Me3tach exhibit dynamic NMR behaviour ia an unusual trigonal twist of the facially coordinated Me3tach ligand (Me3tach and Bu3ttach=1,3,5-trimethyl- and tri-tert-butyl-1,3,5-triazacyclohexane, respectively).

    DOI:10.1021/om700530z
    日期:2007.8.1
    The reaction of a 3‘,4‘-methylenedioxyacetophenone imine (L-H; 1) with nBuLi allows for the synthesis and isolation of a discrete ortho-lithiated imine (L-Li; 2). Through the use of salt metathesis pathways, this monoanionic, chelating N∼C ligand has been employed to produce a series of titanium and zirconium complexes, including L2MX2 (M = Ti, X = Cl (5); M = Zr, X = Cl (3), CH2SiMe3 (4)) and L2TiNtBu
    3',4'-亚甲基二氧基苯乙酮亚胺(LH;1)与正丁基锂的反应可以合成和分离离散的邻位亚胺(L-Li;2)。通过使用盐复分解途径,这种单阴离子,螯合的N〜C配体已被用于生产一系列配合物,包括L 2 MX 2(M = Ti,X = Cl(5); M = Zr, X = Cl(3),CH 2 SiMe 3(4))和L 2 Ti N t Bu(6)。

  • Cyclopentadienyl, indenyl and bis(cyclopentadienyl) titanium imido compounds
    作者:Simon C. Dunn、Philip Mountford、David A. Robson
    DOI:10.1039/a605470f
    日期:——
    The titanium tert-butyl imido compounds [Ti(NBu t )Cl 2 (NC 5 H 4 R-4) n ] (R = H, n = 2 or 3; R = Bu t , n = 2) have been found to be entry points to the half-sandwich η 5 -cyclopentadienyl derivatives [Ti(η 5 -C 5 R′ 4 R″)(NBu t )Cl(NC 5 H 4 R-4)] (R = Bu t , R′ = R″ = H or Me; R = H, R′ = H, R″ = H, Me or Pr i ; R = H, R′ = Me, R″ = Me, Et or C 4 H 7 ), the η 5 -1,2,3-trimethylindenyl species [Ti(η 5 -C 9 H 4 Me 3 )(NBu t )Cl(NC 5 H 4 Bu t -4)] and the bis(η 5 -cyclopentadienyl) compound [Ti(η 5 -C 5 H 5 ) 2 (NBu t )(NC 5 H 5 )], the crystal structure of which has been determined. The complex [Ti(η 5 -C 5 H 5 )(NBu t )Cl(NC 5 H 5 )] readily loses pyridine under vacuum in the solid state to form the binuclear complex [Ti 2 (η 5 -C 5 H 5 ) 2 ( µ-NBu t ) 2 Cl 2 ]. Treatment of [Ti(η 5 -C 5 Me 4 R)(NBu t )Cl(NC 5 H 5 )] (R = Me or Et) with Na[C 5 H 5 ] gives the corresponding mixed-ring sandwich derivatives [Ti(η 5 -C 5 H 5 )(η 5 -C 5 Me 4 R)(NBu t )Cl(NC 5 H 5 )]. Addition of Li[C 9 H 7 ] to [Ti(η 5 -C 5 H 5 )(NBu t )Cl(NC 5 H 5 )] gave the η 5 -cyclopentadienyl, η 3 -indenyl mixed-ring analogue [Ti(η 5 -C 5 H 5 )(η 3 -C 9 H 7 )(NBu t )(NC 5 H 5 )]. The complex [Ti(η 5 -C 5 H 5 ) 2 (NBu t )(NC 5 H 5 )] undergoes a room-temperature cyclopentadienyl ligand-redistribution reaction with [Ti(NBu t )Cl 2 (NC 5 H 5 ) 2 ] forming [Ti(η 5 -C 5 H 5 )(NBu t )Cl(NC 5 H 5 )] in quantitative yield. Variable-temperature NMR spectra for the half-sandwich complexes show that the co-ordinated pyridine exchanges with free pyridine via an associative mechanism. The compound [Ti(η 5 -C 5 H 5 )(η 5 -C 5 Me 4 Et)(NBu t )(NC 5 H 5 )] is also fluxional and exhibits reversible pyridine dissociation at higher temperatures and restricted rotation about the Ti–N (pyridine) bond at lower temperatures.
    叔丁基亚化合物 [Ti(NBu t)Cl 2 (NC 5 H 4 R-4) n ](R = H,n = 2 或 3; R = Bu t ,n = 2)已被发现是半夹心η 5 -环戊二烯基衍生物[Ti(η 5 -C 5 R′ 4 R″)(NBu t )Cl(NC 5 H 4 R-4)] (R = Bu t ,R′ = R″ = H 或 Me ;R = H ,R′ = H ,R″ = H ,Me 或 Pr i ;R=H,R′=Me,R″=Me,Et 或 C 4 H 7)、η 5 -1,2,3-三甲基基化合物[Ti(η 5 -C 9 H 4 Me 3 )(NBu t )Cl(NC 5 H 4 Bu t -4)]和双(η 5 -环戊二烯基)化合物[Ti(η 5 -C 5 H 5 ) 2 (NBu t )(NC 5 H 5 )],其晶体结构已经确定。复合物 [Ti(η 5 -C 5 H 5 )(NBu t )Cl(NC 5 H 5 )] 在固态真空下很容易失去吡啶,形成双核复合物 [Ti 2 (η 5 -C 5 H 5 ) 2 ( µ-NBu t ) 2 Cl 2 ]。用 Na[C 5 H 5 ]处理[Ti(η 5 -C 5 Me 4 R)(NBu t )Cl(NC 5 H 5 )] (R = Me 或 Et),可得到相应的混环夹心衍生物[Ti(η 5 -C 5 H 5 )(η 5 -C 5 Me 4 R)(NBu t )Cl(NC 5 H 5 )]。在[Ti(η 5 -C 5 H 5 )(NBu t )Cl(NC 5 H 5 )] 中加入 Li[C 9 H 7 ],可得到 η 5 -环戊二烯基、η 3 -基混合环类似物[Ti(η 5 -C 5 H 5 )(η 3 -C 9 H 7 )(NBu t )(NC 5 H 5 )]。 复合物 [Ti(η 5 -C 5 H 5 ) 2 (NBu t )(NC 5 H 5 )] 与 [Ti(NBu t )Cl 2 (NC 5 H 5 ) 2 ] 发生室温环戊二烯配体再分布反应,形成 [Ti(η 5 -C 5 H 5 )(NBu t )Cl(NC 5 H 5 )] 复合物,产量定量。半夹心复合物的变温核磁共振光谱显示,配位吡啶与游离吡啶通过缔合机制发生交换。化合物[Ti(η 5 -C 5 H 5 )(η 5 -C 5 Me 4 Et)(NBu t )(NC 5 H 5 )]也具有通性,在较高温度下表现出可逆的吡啶解离,在较低温度下表现出围绕 Ti-N (吡啶)键的受限旋转。
