摘要：

Sublimation of (Tsi-Li) . 2THF (Tsi = -C(Si(CH3)(3))(3)) at 180 degrees C and 10(-4) hPa gives (Tsi-Li) 1.5 THF in very low yield. The X-ray structure determination shows an almost linear [Tsi-Li-Tsi](-) anion connected by short agostic Li ... C contacts with the threefold THF-coordinated Li-cation. Base-free Tsi-Li, solved in toluene is decomposed by oxygen, forming the strawberry-colored ketone O=C(SiMe3)(2), which forms an 1:1 adduct with undecomposed Tsi-Li. The X-ray structure elucidation of this compound is also discussed.
