  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.
