Abstract
Complexes of t-BuLi monomer with 1,4,7-trimethyl-1,4,7-triazacyclonona ne (TMTAN, 3-CH3) and tris(N,N-dimethyl-2-aminoethyl)amine (4-CH3) wer e identified by C-13-NMR. Rapid elimination of LiN(CH2CH2NMe2)(2) take s place from the free CH2CH2NMe2 group of t-BuLi-4-CH3. BuLi complexes of hexamethyltriethylenetetramine (5-CH3) and octamethylpentaethylene hexamine (6) behave similarly, as does 4-CH2Li. Complexes of BuLi olig omers are lithiated at free N-CH3.
