  [1]Ferrocenophanes, [1]Chromarenophanes, and [1]Vanadarenophanes with Aluminium and Gallium in Bridging Positions

  摘要：

  Aluminum- and gallium-bridged [1] ferrocenophanes (4a, 4b), [1] chromarenophanes (5a, 5b), and [1] vanadarenophanes (6a, 6b) were synthesized from the respective dilithiated sandwich compounds with element dichlorides (Me(2)Ntsi)ECl2 [E = Al, Ga; Me(2)Ntsi = C(SiMe3)(2)(SiMe2NMe2)] in moderate to high isolated yields (54-97%). The new intramolecularly stabilized aluminum compound (Me(2)NCH(2)tsi) AlCl2 (2a) was synthesized, but was proven to be unreactive with respect to [Fe(LiC5H4)(2)]center dot 2/3TMEDA. The diamagnetic species 2a, 4a, 4b, 5a, and 5b were characterized by NMR spectroscopy (H-1, C-13, Al-27), CHN elemental analysis, and mass spectrometry, whereas the paramagnetic compounds 6a and 6b were characterized by IR spectroscopy, CHN elemental analysis, and mass spectrometry. In addition, the molecular structures of compounds 2a, 4a, 4b, 5a, 5b, 6a, and 6b were determined by single-crystal X-ray analysis. All [1] cyclophanes are strained species, as revealed by the following tilt angles alpha [deg]: 14.33(14) (4a), 15.83(19) (4b), 11.81(9) (5a), 13.24(13) (5b), 14.65(14) (6a), and 15.63(14) (6b).

  Attachment of the New Bulky Ligand (Me₃Si)₂(Me₂NMe₂Si)C to Li, Hg, Al, Ga, and Sn. Crystal Structures of [Li{C(SiMe₃)₂(SiMe₂NMe₂)}(THF)₂], [Hg{C(SiMe₃)₂(SiMe₂NMe₂)}₂], [Al{C(SiMe₃)₂(SiMe₂NMe₂)}X₂] (X = Cl, Ph), and [Ga{C(SiMe₃)₂(SiMe₂NMe₂)}Cl₂]

  摘要：

  The organolithium reagent [Li{C(SiMe3)(2)(SiMe2NMe2)(THF)(2)] (1) is readily obtained by reaction of the chloride (Me3Si)(2)(Me2NMe2Si)CCl with LiBu in THF (tetrahydrofuran) at low temperature. Reactions of 1 with HgBr2, AlCl3, GaCl3, and SnCl4 give [Hg{C(SiMe3)(2)(SiMe2NMe2)}(2)] (2), [Al(C(SiMe3)(2)(SiMe2NMe2)}Cl-2)] (3), Ga{C(SiMe3)(2)(SiMe2NMe2)}Cl-2 (5), and [Sn{C(SiMe3)(2)(SiMe2NMe2)}Cl-3] (6), respectively, and treatment of 3 with LiPh gives [Al(C(SiMe3)(2)(SiMe2NMe2)}Ph-2] (4). Crystal structure determinations have shown that there is intramolecular coordination of the N atom to the metal M, with formation of a planar four-membered C-Si-N-M ring, in 1, 3, 4, and 5 (but not 2). Engagement of the lone pair on N in coordination with Al in 3 results in an exceptionally long Si-N bond length of 1.875(2) Angstrom, some 0.16 Angstrom longer than that in 2 and in simple silylamines generally; the Si-N bond is possibly shorter in 4 (1.851(2) Angstrom) and 5 (1.858(4) Angstrom), and is markedly so in 1 (1.796(4) Angstrom), but still notably long. The lengths of the N-metal bonds in these compounds are similar to those between alkylamines and the metals in coordination compounds, indicating that at least in these systems the N atoms in the silylamines coordinate as strongly as those in the organic amines. Reaction of 6 with MeOH occurs exclusively at the Si-N bond to give [Sn{C(SiMe3)(2)(SiMe2OMe)}Cl-3], that of 2 with ICl or CF3CO2H gives [Hg{C(SiMe3)(2)(SiMe2Cl)}(2)] and [Hg{C(SiMe3)(2)(SiMe2O2CCF3)}(2)], respectively, and that of 1 with ICH2CH2I gives the iodide (Me3Si)(2)(Me2NMe2Si)CI.

  of 59.6 and 59.1 kJ mol-1, respectively. Compound 2b reacted with [Pt(PEt3)3] to give the ring-open product [(eta6-C6H6)Moeta6-C6H5[GaPh(Me2Ntsi)]}] (3b). The molecular structure of 3b was deduced from a single-crystal X-ray determination. The formation of the unexpected platinum-free product 3b can be rationalized by assuming that benzene reacted with 2b in a 1:1 ratio. Through a series of 1H NMR experiments
