  摘要：

  Reaction of the lithate [Li(THF)(4)][CH2SiMe2C(SiMe3)(2)LiC(SiMe3)(2)SiMe2CH2] with (KOBu)-Bu-t in THF has given the organopotassium reagent (THF)(2)KC(SiMe3)(2)SiMe2CH2CH2Me2Si(Me3Si)(2)CK(THF)(2), 8, and reaction of HC(SiMe3)(2)SiMe2CH2CH2Me2Si(Me3Si)(2)CH with KMe in benzene has given the related ether-free species (C6H6)(2)KC(SiMe3)(2)SiMe2CH2CH2Me2Si-(Me3Si)(2)CK(C6H6)(2), 7. The structures of 7 and 8 have been confirmed by X-ray studies which indicate that both compounds show K ... Me contacts in the range 3.3-3.5 Angstrom. The ether-free reagent 7 reacted with YbI2 in benzene to give the cyclic Yb(II) derivative CH2SiMe2(SiMe3)(2)YbC(SiMe3)(2)SiMe2CH2, which was found to be somewhat more stable toward Et2O than the I previously studied Yb{C(SiMe3)(3)}(2). Reaction of the lithate [Li(TMEDA)(2)][CH2SiMe2C(SiMe3)(2)LiC(SiMe3)(2)SiMe2CH2] (2a) with ZnCl2 in THF gave a cyclic compound CH2SiMe2C(SiMe3)(2)ZnC(SiMe3)(2)SiMe2CH2, which is stable toward boiling aqueous THF. An X-ray study shows that the angle at Zn is 170 degrees. In contrast, the reactions of 2a with SnCl4 or Me2SnCl2 gave linear species ClX2SnC(SiMe3)(2)SiMe2CH2CH2Me2Si(Me3Si)(2)CSnX2Cl, X = Cl or Me, the structures of which were confirmed by single-crystal X-ray diffraction studies.

  The compound (Me(3)Si)(2)CHSiMe(2)CH(2)}(2) has been prepared and metalated with MeLi to give the chelated lithate ion [CH(2)SiMe(2)C(SiMe(3))(2)LiC(SiMe(3))(2)SiMe(2)CH(2)](-), which was isolated as its [Li(TMEDA)(2)] salt (TMEDA = N,N,N',N'-tetramethylethylenediamine). The potential of this salt as a source of the very bulky dicarbanionic ligand (Me(3)Si)(2) (C) over bar SiMe(2)CH(2)}(2) was demonstrated by its reaction with HgBr2 in THF to give the chelated mercury compound [CH(2)SiMe(2)C(SiMe(3))(2)HgC(SiMe(3))(2)SiMe(2)CH(2)]. The crystal structures of the salt and the mercurial compound were determined.

  The title lead(II) derivative was obtained as dark blue crystals by treatment of PbCl2 with [Li(TMEDA)(2)][CH2SiMe2C(SiMe3)(2)LiC(SiMe3)(2)SiMe2CH2] (TMEDA = N,N,N',N'-tetramethylethylenediamine) in tetrahydrofuran and its structure determined by X-ray diffraction. The compound is in. effect the first dialkylead(II) species to be structurally characterized. The C-Pb-C angle is 117.1(2)degrees. Analogous treatment of SnCl2 yielded a yellow solid, which was judged from spectroscopic data to be the TMEDA complex of the analogous stannacycloalkane.
