Abstract

Reaction of SiMe₄ or CH₂(SiMe₃)₂ in n-C₆H₁₄ with LiBuⁿ(pmdeta) affords in high yield Li(CH₂SiMe₃)-(pmdeta) or Li(CH(SiMe₃)₂)(pmdeta), (2), respectively, the latter also being available from Li(CH(SiMe₃)₂)-(tmeda), (1), and pmdeta; crystalline compound (1) and (2) are monomers (Ebullioscopy, C₆H₁₂), and for (2) this is also shown by X-ray crystallography, with the short Li-C distance [2.13(5)Å] indicative of a covalent bond.
