摘要：

Silyl dianions [(Me3Si)(2)Si(CH2)(n)Si(SiMe3)(2)](2-) (n = 1, 4; 2, 5; 3, 6) as [K(18-crown-6)](+) salts have been prepared by reactions of (Me3Si)(3)Si(CH2)(n)Si(SiMe3)(3) (n = 1, 1; 2, 2; 3, 3) with t-BuOK and 18-crown-6 in DME. Characterization of these new silyl dianions, X-ray crystal structures of 2, 3, and 5, and improved synthesis of 1-3 are reported.
