  • Scandium and yttrium complexes of the diamide–diamine donor ligand (2-C5H4N)CH2N(CH2CH2NSiMe3)2: chloride, primary and secondary amide, benzamidinate and alkyl functionalised derivatives
    作者:Michael E. G. Skinner、Philip Mountford
    DOI:10.1039/b111469g
    日期:2002.4.9
    Five- and six-coordinate scandium and yttrium complexes of the recently described diamide–diamine donor ligand N2NN′ (where H2N2NN′ = (2-C5H4N)CH2NCH2CH2N(H)SiMe3}2) are described. Reaction of ScCl3 with Li2N2NN′ gave five-coordinate [ScCl(N2NN′)] 1 in excellent yield. The corresponding reaction with YCl3 in tetrahydrofuran (thf) or pyridine (py) solution afforded “ate” complexes best described as [YCl(N2NN′)(L)]·1.5(LiCl) (L = thf 2 or py 3). The two chloride complexes 1 and 2 are useful starting materials for primary and secondary amide, benzamidinate and alkyl complexes of Sc and Y supported by the N2NN′ ligand. Thus reaction of 1 or 2 with LiN(SiMe3)2·Et2O, LiNMe2 or LiNHR (R = tBu or Ar, where Ar = 2,6-C6H3iPr2) gave the corresponding five-coordinate amide derivatives [M(NRR″)(N2NN′)] (M = Sc, R = R″ = SiMe34 or Me 6, or R = H, R″ = tBu 8 or Ar 9; M = Y, R = R″ = SiMe35, or R = H, R″ = Ar 10). The crystal structure of 5 is described. The σ-bond metathesis reaction of [Sc(NMe2)(N2NN′)] 6 with ArFNH2 (ArF = C6F5) gave the corresponding primary flurophenylamide derivative 7. The reaction of 1 or 2 with Li[PhC(NSiMe3)2] gave the fluxional, six-coordinate benzamidinate derivatives [MPhC(NSiMe3)2}(N2NN′)] (M = Sc 11 or Y 12), the crystal structures of which are reported. Finally, reaction of 1 with LiCH2SiMe3 formed the alkyl derivative [Sc(CH2SiMe3)(N2NN′)] 13 in reasonable yield; the crystal structure of 13 is described.
    最近报道的二酰胺-二胺供体配体N2NN'(其中H2N2NN' = (2-C5H4N)CH2NCH2CH2N(H)SiMe3}2)的五配位和六配位钪和钇配合物。将ScCl3与Li2N2NN'反应得到了高产率的五配位[ScCl(N2NN')] 1。在四氢呋喃(thf)或吡啶(py)溶液中,将YCl3与Li2N2NN'反应得到了最佳描述为[YCl(N2NN')(L)]·1.5(LiCl)的“ate”配合物(L = thf 2或py 3)。两种氯配合物1和2是制备由N2NN'配体支撑的Sc和Y的一级和二级酰胺、苯甲酰亚胺和烷基配合物的重要起始材料。因此,将1或2与LiN(SiMe3)2·Et2O、LiNMe2或LiNHR(R = tBu或Ar,其中Ar = 2,6-C6H3iPr2)反应得到了相应的五配位酰胺衍生物[M(NRR')(N2NN')](M = Sc,R = R' = SiMe34或Me 6,或R = H,R' = tBu 8或Ar 9;M = Y,R = R' = SiMe35,或R = H,R' = Ar 10)。描述了5的晶体结构。[Sc(NMe2)(N2NN')] 6与ArFNH2(ArF = C6F5)的σ-键置换反应得到了相应的一级氟苯甲酰胺衍生物7。将1或2与Li[PhC(NSiMe3)2]反应得到了动态的六配位苯甲酰亚胺衍生物[MPhC(NSiMe3)2}(N2NN')](M = Sc 11或Y 12),报告了其晶体结构。最后,将1与LiCH2SiMe3反应形成了合理的产率的烷基衍生物[Sc(CH2SiMe3)(N2NN')] 13;描述了13的晶体结构。

  • Substituted triazines and pyrimidines from 1,3,5-triazine and a lithium amidinate, alkyl- or 1-azaallyl

    日期:——
    Treatment of 1,3,5-triazine 1 with an alkyllithium LiR [R = a Me, b Bun, c But, d Ph, e CH2TMS, f CH(TMS)2 or g Si(TMS)3(THF)3] yielded the appropriate 1 ∶ 1 addition product 2a–2g, which upon hydrolysis gave the corresponding mono-substituted dihydro-1,3,5-triazine HNC(H)NC(H)(R)NCH 3a–3g. 1H NMR spectral data showed that the 1,4-dihydrotriazine 3f in toluene-d8 was in equilibrium with its 1,2-dihydro tautomer. Heating 3f with EtOH or H2O in an acidic medium led to the facile cleavage of a C–Si bond and the formation of EtOTMS or (TMS)2O, respectively. The 13C and 15N NMR spectral data are compared with those obtained by B3LYP/6-31+G* computations on the model compound NC(H)NCH2NCH. Treatment of 1 with the lithium amidinate [LiN(TMS)C(Ph)NTMS}]2 or with 1-azaallyllithium [LiN(TMS)C(Ph)C(H)TMS}(tmen)], [LiN(TMS)C(But)C(H)TMS}]2 or [LiN(TMS)C(Ph)C(TMS)2}(THF)2] yielded 2-phenyltriazine 5, 4-phenylpyrimidine 6, 4-tert-butylpyrimidine 9 or, in poor yield, the new 4-phenyl-5-trimethylsilylpyrimidine 7, respectively. In the case of 1 and [LiN(TMS)C(But)C(H)TMS}]2 an intermediate was isolated—the thermally unstable [LiN(TMS)C(H)NC(H)NC(H)C(H)C(But)NTMS}]n8. A pathway is proposed involving the 1,4-addition of the lithium compound to 1,3,5-triazine 1, followed by a 1,3-trimethylsilyl shift, ring-opening and the formation of a new C–C or C–N bond to form the appropriate aromatic heterocycle.
