Complexes of t-BuLi monomer with 1,4,7-trimethyl-1,4,7-triazacyclononane (TMTAN, 3-CH3) and tris(N,N-dimethyl-2-aminoethyl)amine (4-CH3) were identified by 13C-NMR. Rapid elimination of LiN(CH2CH2NMe2)2 takes place from the free CH2CH2NMe2 group of t-BuLi·4-CH3. BuLi complexes of hexamethyltriethylenetetramine (5-CH3) and octamethylpentaethylenehexamine (6) behave similarly, as does 4-CH2Li. Complexes
