  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 reaction between the lithate [Li(THF)(4)]-[CH2SiMe2C(SiMe3)(2)LiC(SiMe3)(2)SiMe2CH2] and MnCl2 has given a chloride-bridged high-spin lithium manganate, isolated as Li(THF)(2.75)(Et2O)(0.25)(mu-Cl)MnC(SiMe3)(2)SiMe2CN2CH2Me2Si(Me3Si)(2)C, shown by an X-ray study to contain three-coordinate planar manganese. The ligand precursor HC(SiMe3)(2)SiMe2CH2CH2Me2Si(Me3Si)(2)CH reacts with methylcesium to give a compound isolated after recrystallization from benzene as (C6H6)(3)CsC(SiMe3)SiMe2CH2CH2Me2Si(Me3Si)(2)CCs(C6H6)(3), in which benzene solvate molecules show a variety of hapticities.
